Question About GridView Update Query
Nov 15, 2007
I try to calculate a field value and update other. It almost works
UPDATE t_Shopping_cart SET [Product_code] = @Product_code, [Quantity] = @Quantity, [Total] = Quantity * Price WHERE ([Product_code] = @Product_code)
I try to update t_Shopping_cart table with quantity values from grid view and calculate sum of products (quantity*Price). Best I can get is that quantity values are old. Some comments about my query:Price is also a field in table and control. [Product_code] = @Product_code part is probably not needed.
Any ideas?

Hi All,
I am new to development of asp. I have an SQLDataSource set as the data source for a grid view. When I click on the edit link in the Gridview, change the data, and click update, the old data is still displayed in the row.
I found exact same issue as here -- http://forums.asp.net/thread/1217014.aspx
Solution in the above thread is to add this
{ if (reader != null) reader.Close(); } conn.Close();
How do I apply above solution in my situation ?
I am updating through stored procedure.and don't have code at background. My code is
Datasource :
<asp:SqlDataSource
ID="ds"
runat="server"
ConnectionString="<%$ ConnectionStrings:ds %>"
CancelSelectOnNullParameter="False"
ProviderName="<%$ ConnectionStrings:ds.ProviderName%>"
UpdateCommand="usp_save"
UpdateCommandType="StoredProcedure"
EnableCaching="False">
<UpdateParameters>
<asp:Parameter Name="field1" Type="String" />
<asp:Parameter Name="field2" Type="String" />
<asp:Parameter Name="field3" Type="String" />
<asp:Parameter Name="field4" Type="String"/>
<asp:ControlParameter Name="field5" Type="String" ControlID = "label7" />
</UpdateParameters>

I am trying to update a field in gridview. My update is not working, sort of. The original value is being updated with a NULL value when I click on the update button.here is my code <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource2" AutoGenerateEditButton="True" DataKeyNames="rqt_id">UpdateCommand="UPDATE [rqt_data] SET [rqt_title]=@rqt_title WHERE [rqt_id] = @rqt_id" > <asp:Parameter Name="rqt_title" Type="String" /> the field rqt_title is set up as a NVarChar(25) in the db. I can't specify that for the Type property. Could that be the issue?thx

design view is great, just drag on a gridview make it link to my database and poof there is all my data! I can even click the "allow editting button" and poof I can edit my data.
But how do assign validation rules? because atm if someone tries to edit my name field at puts in "asdfasdkfhdsgasdgaga" which is too long, clicks update it goes to a horrible error page. How can I catch these errors and make a nice message instead?
Thanks very much

I have a GridView that gets data from an SqlDataSource. It works fine, but now when I want to filter the results and add more parameters to my sql query, nothing happens. My initial select statement in the SqlDataSource contains only 2 parameters, so now when a user clicks a Button, onclick I call a function that is supposed to change the select statement of the SqlDataSource, add 2 more parameters taken from 2 controls, and then update the GridView. This is what I use: dataSource.SelectCommand = "new select command here"; dataSource.SelectParameters.Add("State", txtState.Text); dataSource.SelectParameters.Add("City", txtCity.Text); grid.DataBind(); It compiles, but when I click the button to filter the results, the GridView always looks the same as if nothing happened. I do not know if this is the right way to do it, or am I on the wrong track? Help is appreciated. Thank you in advance.

When I attempt to update using a stored procedure I get the error 'Incorrect syntax near sp_upd_Track_1'. The stored procedure looks like the following when modified in SQLServer:
ALTER PROCEDURE [dbo].[sp_upd_CDTrack_1]
(@CDTrackName nvarchar(50),
@CDArtistKey smallint,
@CDTitleKey smallint,
@CDTrackKey smallint)
AS
BEGIN
SET NOCOUNT ON;
UPDATE [Demo1].[dbo].[CDTrack]
SET [CDTrack].[CDTrackName] = @CDTrackName
WHERE [CDTrack].[CDArtistKey] = @CDArtistKey
AND [CDTrack].[CDTitleKey] = @CDTitleKey
AND [CDTrack].[CDTrackKey] = @CDTrackKey
END
But when I use the following SQL coded in the gridview updatecommand it works:
"UPDATE [Demo1].[dbo].[CDTrack]
SET [CDTrack].[CDTrackName] = @CDTrackName
WHERE [CDTrack].[CDArtistKey] = @CDArtistKey
AND [CDTrack].[CDTitleKey] = @CDTitleKey
AND [CDTrack].[CDTrackKey] = @CDTrackKey"
Whats the difference? The storedproc executes ok in sql server and I guess that as the SQL version works all of my databinds are correct. Any ideas, thanks, James.

I've got a listbox that displays a list of employee's names. The employee number is the value stored in the listbox. I then have a vaccinations gridview that displays all the vaccinations received by the selected employee in the listbox. For some reason, when I click edit and modify a record and then click update it doesn't want to actually update the record. It just appears to do a postback and redisplay the record without any changes. My sqldatasource control is configured as follows: SelectCommand="SELECT * FROM [tblVaccinations] WHERE ([EmpNum] = @EmpNum)" @empnum = mylistbox.selectedvalue the update command is as follows: UpdateCommand="UPDATE [tblVaccinations] SET [EmpNum] = @EmpNum, [VacType] = @VacType, [VacIssueDate] = @VacIssueDate, [VacExpDate] = @VacExpDate, [VacInstitution] = @VacInstitution WHERE [VaccinationNum] = @VaccinationNum"

I have a gridview that is tied to a SQLDataSource control which is inside an update panel.
What I'm trying to accomplish is when the page is loaded the gridview is filled from the SQLDataSource. I have some textboxes also on the page so that the user can add new items to the gridview. The update panel trigger is tied to my code behind page through a button click which added the new data to the DB with an INSERT statement. Since the gridview was inside the update panel I thought when I placed the new data into the DB and the update panel caused the portion of the page that holds the gridview to refresh that the gridview would show the newly added data but it is not.
I am missing something but I do not know what. I tried adding a gridview1.databind() and SQLDataSource1.DataBind() but niether caused the update of the gridview as I had hoped.
Thanks for any of your help.

Hi all
I have a GridView on an aspx page, that is enabled for editing, deletion and sorting.
In the Page_Load event of the aspx page, i add a SqlDataSource to the page, and bind the source to the GridView.
When i click the update, or delete button, it makes a PostBack, but nothing is affected. I'm sure this has got something to do with the parameters.
First, i tried having the GridView.AutoGenerateColumns set to True. I have also tried adding the columns manually, but no affect here either.
The code for setting the commands, and adding the SqlDataSource to the page are as follows:
string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName; string selectCommand = "SELECT * FROM rammekategori"; SqlDataSource ds = new SqlDataSource(strProvider, strConn, selectCommand); ds.ID = "RammeKategoriDS"; ds.UpdateCommand = "UPDATE rammekategori SET Kategoribeskrivelse = @Kategoribeskrivelse WHERE (Kategorinavn = @Kategorinavn)"; ds.DeleteCommand = "DELETE FROM rammekategori WHERE (Kategorinavn = @Kategorinavn)"; Parameter Kategorinavn = new Parameter("Kategorinavn", TypeCode.String); Parameter Kategoribeskrivelse = new Parameter("Kategoribeskrivelse", TypeCode.String); ds.UpdateParameters.Add(Kategorinavn); ds.UpdateParameters.Add(Kategoribeskrivelse); ds.DeleteParameters.Add(Kategorinavn);
Page.Controls.Add(ds);
SqlDataSource m_SqlDataSource = Page.FindControl("RammeKategoriDS") as SqlDataSource;
if (m_SqlDataSource != null) { this.gvRammeKategorier.DataSourceID = m_SqlDataSource.ID; }
As mentioned - no affect at all!
Thanks in advance - MartinHN

<!-- Trying
to create a GridView Survey form:
Hi [User]
Do you have these assets?
[Gridview]
Tag Number Response
123
[Yes ] [No] [Comments textbox]
234
[Yes ] [No] [Comments textbox]
Goal: The desire
is for the user to click Yes or No and have the database updated with the
user's name, date, response and any comments.
So far, I have
created SqlDataSource with Select and Update commands, created the gridview and
response buttons, setup the RowCommand and On_Updating Functions.
Problems:1) If I call the update() function for SqlDataSource1 and misuse the Defaultvalue parameters to run the sql, no update is posted to the database.
2) If I use the On_Update function to set the parameter values, I get "Data type mismatch in criteria expression." (Additionally, the On_Update function runs twice which I don't understand)Can anyone tell
me what/why? (and how to fix it?)Sorry for the deluge, but here is the code:

Hi,
Using VS.NET 2008 Beta2, and SQL Server 2005.
I have a gridview bound to a linq data source, and when trying to update a row, I get an exception that no rows were modified.
The query generated is:
UPDATE [dbo].[package]
SET [owner_id] = @p5
WHERE ([package_id] = @p0) AND ([title] = @p1) AND ([directory] = @p2) AND ([owner_id] = @p3) AND ([creation_date] = @p4)
-- @p0: Input Int32 (Size = 0; Prec = 0; Scale = 0) [20006]
-- @p1: Input String (Size = 22; Prec = 0; Scale = 0) [Visual Studio.NET 2005]
-- @p2: Input String (Size = 26; Prec = 0; Scale = 0) [MSI_Visual_Studio.NET_2005]
-- @p3: Input Int32 (Size = 0; Prec = 0; Scale = 0) [10000]
-- @p4: Input DateTime (Size = 0; Prec = 0; Scale = 0) [11/07/2007 12:00:00 a.m.]
-- @p5: Input Int32 (Size = 0; Prec = 0; Scale = 0) [10001]
-- Context: SqlProvider(Sql2005) Model: AttributedMetaModel Build: 3.5.20706.1
If I run it manually on sql server, it fails until the directory column is removed. The type is varchar(50), with a uniqueness constraint. However, this is same type as the title column, which doesn't have this problem.
Thanks,
Jessica

Hi all,
I have a gridview bound with a SQLDataSource. I am using the Update feature of the SQLDataSource to update a SQL Server database with values entered into the gridview. However I am not getting it to work. I believe this is due to the controls that contain the user entries are not the gridview itself, but rather child controls within the gridview. I have been using the names of the actual controls but nothing happens. Upon submit, the screen returns blank, and the database is not updated. Here is some code:
<asp:GridView ID="GridEditSettlement" runat="server" AutoGenerateColumns="False" BackColor="Navy"
BorderColor="IndianRed" BorderStyle="Solid" Font-Names="Verdana" Font-Size="X-Small" DataSourceID="SqlDataSource_grid" AllowPaging="True" AllowSorting="True" ForeColor="White" DataKeyNames="legid">
<Columns>
<asp:CommandField ShowEditButton="True" CancelImageUrl="~/App_Graphics/quit.gif" CancelText="" EditImageUrl="~/App_Graphics/EditGrid.GIF" EditText="" UpdateImageUrl="~/App_Graphics/save.gif" UpdateText="" ButtonType="Image" />
<asp:BoundField DataField="StartDate" HeaderText="Start Date" ReadOnly="True" />
<asp:BoundField DataField="EndDate" HeaderText="End Date" ReadOnly="True" />
<asp:BoundField DataField="CounterpartDealRef" HeaderText="CP Deal Ref" ReadOnly="True" />
<asp:TemplateField HeaderText="Preliminary Settlement Price" ><ItemTemplate>
<asp:Label ID=lblPreliminary runat=server Text='<%# Bind("PrimarySettlementPrice") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID=txtPrimaryPrice Text='<%# Bind("PrimarySettlementPrice") %>'></asp:TextBox>
</EditItemTemplate></asp:TemplateField>
<asp:TemplateField HeaderText="Agreed Settlement Price"><ItemTemplate>

</EditItemTemplate></asp:TemplateField>
<asp:BoundField DataField="Volume" HeaderText="Volume" ReadOnly="True" />
<asp:BoundField DataField="Price" HeaderText="Price" ReadOnly="True" />

<asp:BoundField DataField="DeliveryDate" HeaderText="Delivery Date" ReadOnly="True" />
<asp:TemplateField HeaderText="LegId" SortExpression="LegId">
<ItemTemplate>
<asp:Label ID="lblLegID" runat="server" Text='<%# Bind("LegId") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID=txtLegID Text='<%# Bind("LegId") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
<RowStyle BackColor="#FFFF66" ForeColor="#333333" />
<EditRowStyle BackColor="#FFFF66" Font-Names="Verdana" Font-Size="X-Small" ForeColor="#333333" />
<PagerStyle ForeColor="White" />
<AlternatingRowStyle BackColor="White" ForeColor="#333333" />
</asp:GridView>
<br />
<asp:SqlDataSource ID="SqlDataSource_grid" runat="server" ConnectionString="<%$ ConnectionStrings:DealCaptureDev %>" SelectCommand="sp_get_single_deal" SelectCommandType="StoredProcedure" UpdateCommand="Update trDealLeg Set PrimarySettlementPrice=@primarysettlement, AgreedSettlementprice=@agreedsettlement, LastUpdate=GetDate(), LastUpdateBy=Session('userid') Where LegID=@legid" EnableCaching="True" ConflictDetection="CompareAllValues" ProviderName="System.Data.SqlClient">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="" Name="dealnum" QueryStringField="deal"
Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:ControlParameter ControlID="txtLegId" PropertyName="Text" Name="legId" />
<asp:ControlParameter ControlID="txtPrimarySettlement" Name="primarysettlement" PropertyName="Text" />
<asp:ControlParameter ControlID="txtAgreedSettlement" Name="agreedsettlement" PropertyName="Text"/>
<asp:SessionParameter DefaultValue="" Name="userid" SessionField="userid" />
</UpdateParameters>
</asp:SqlDataSource>
As seen above, controls such as txtPrimarySettlement are referenced but the update is not successful. The text boxes are within the GridEditSettlement gridview. In the .aspx code I cannot use FindControl (at least I don't think it will work).
So the questions are: Is it possible to reference the child controls, if so - how? Is there another way to do this, such as in the vb code behind - in the either the gridview's RowUpdating event or the SQLDataSource's Updating event.
What is the best approach? Anyone come up against this issue before?
Thanks,
KB

I have a GridView dispalying from a SQLServerDataSource that is using a SQL Select Union statement (like the following):
SELECT FirstName, LastNameFROM MasterUNION ALLSELECT FirstName, LastNameFROM CustomORDER BY LastName, FirstName
I am wondering how to create Update and Insert statements for this SQLServerDataSource since the select is actually driving from two different tables (Master and Custom). Any ideas if or how this can be done? Specifically, I want the Custom table to be editable, but not the Master table. Any examples or ideas would be very much appreciated!
Thanks,
Randy

Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having. Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!

Hi! Select gets all records that contains illegal chars... Ok, to replace '[' { and some other chars I will make AND '% .. %' and place other intervals, that is not the problem.The problem is: How to replace not allowed chars ( ! @ # $ % ^ & * ( ) etc. ) with '_' ?I have seen that there is a function REPLACE, but can't figure out how to use it. 1 SELECT user_username
2 FROM users
3 WHERE user_username LIKE '%[!-)]%';

I'm looking for a query that can "batch" update one table from another. For example, say there are fields on both tables like this:
KeyField
Value1
Value2
Value3
The two tables will match on "KeyField". I would like to write one SQL query that will update the "Value" fields in Table1 with the data from Table2 when there is a match.

Hello, I have the following query in Access 2000 that I need to convertto SQL 2000:UPDATE tblShoes, tblBoxesSET tblShoes.Laces1 = NullWHERE (((tblShoes.ShoesID)=Int([tblBoxes].[ShoesID])) AND((tblBoxes.Code8)="A" Or (tblBoxes.Code8)="B"))WITH OWNERACCESS OPTION;The ShoesID in the tblShoes table is an autonumber, however the recordsin the tblBoxes have the ShoesID converted to text.This query runs ok in Access, but when I try to run it in the SQLServer 2000 Query Analizer I get errors because of the comma in the"UPDATE tblShoes, tblBoxes" part. I only need to update the tblShoesfield named Laces1 to NULL for every record matching the ones in thetblBoxes that are marked with an "A" or an "B" in the tblBoxes.Code8field.Any help would be greatly appreciated.JR

I have an update query running which to just now has been running for 22 hours running on two tables 1 a lookuptable that has just been created within the batch the other a denormalised table for doing data analysis on
the query thats causing teh problem is
--//////////////////////////////////// this is the one thats running
Print 'Update Provider 04-05 EmAdmsCount12mths : ' + CAST(GETDATE() AS varchar)
GO
Update Provider_APC_2004_05
set EmAdmsCount12mths =
(Select COUNT(*)-1
from Combined_Admissions
where ((Combined_Admissions.NHSNumber = Provider_APC_2004_05.NHSNumber) or
(Combined_Admissions.PASNUMBER = Provider_APC_2004_05.PDDISTNO)) and
(Combined_Admissions.AdmDate BETWEEN DateAdd(yyyy,-1,Provider_APC_2004_05.AdmDate) AND Provider_APC_2004_05.AdmDate) AND
Combined_Admissions.AdmMethod like 'Emergency%')-- and
-- CA.NHSorPrivate = 'NHS'))
FROM Provider_APC_2004_05, Combined_Admissions
any help in improving speed would be most welcome as there are 3 more of these updates to run right after this one and the analysis tables are almost double the size of this one

Hi,
I use WVD and SQL Express 2005.
I have a table “SignIn� that one of fields inserted automatically by getdate()
And I have GridView that I use to display this table because I would like take advantage of GridView sorting and paging methods that are embedded in.
Currently I display all records at once.
My problem is how to make the GridView show today’s records only.
I tried this code below, but I get only this message “There are no data records to display.�
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:RC1 %>"
ProviderName="<%$ ConnectionStrings:RC1.ProviderName %>"
SelectCommand="SELECT [student_ID], [SignIn], [SignOut], [Location] FROM [Stud_data] WHERE (CONVERT(VARCHAR(10),[SignIn],101) = @SignIn)">
<SelectParameters>
<asp:QueryStringParameter Name="SignIn" QueryStringField="Format(Now, "M/dd/yyyy")" Type="DateTime" />
</SelectParameters>
</asp:SqlDataSource>
Help Please!

Hi
I have a business search box and gridview pair. When the user enters a business name, the search results are displayed. I also generate a "more information" link which takes the user to a new page, passing the business name ("memberId")to this page (see the template field below).
The problem I have is if the name contains a QUOTE (') or other special characters. The "memberId" is chopped off at the quote (e.g. "Harry's Store" is passed as "Harry").
Can anyone tell me a way around this please? Is there anything I can do with the Eval method?
Kind regards,
Garrett
<asp:TemplateField HeaderText="More Info">
<ItemTemplate>
<a href='member_page.aspx?memberId=<%# Eval("co_name") %>'>more</a>
</ItemTemplate>
<ItemStyle Font-Bold="False" />
</asp:TemplateField>

This is my first website done in ASP.NET and SQL Server 2005. I haven't ran into any major problems, until I tried to run an update on some rows. I've searched everywhere online, only to be stuck at the end of the day. I will post the code I have for the button that triggers it. I'll be crossing my fingers! int eid = Int32.Parse(Request.QueryString["id"]);
string updateSQL = "UPDATE Events SET event_title = @event_title, event_date = @event_date, ";
updateSQL += "event_time = @event_time, event_location = @event_location, event_description = @event_description WHERE (eid = @eid)";
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd = new SqlCommand(updateSQL, con);
cmd.CommandType = CommandType.Text;
// Add the parameters.
cmd.Parameters.AddWithValue("@event_title", txtEditTitle.Text);
cmd.Parameters.AddWithValue("@event_date", txtEditDate.Text);
cmd.Parameters.AddWithValue("@event_time", txtEditTime.Text);
cmd.Parameters.AddWithValue("@event_location", txtEditLocation.Text);
cmd.Parameters.AddWithValue("@event_description", txtEditDescription.Text);
cmd.Parameters.AddWithValue("@eid", eid);
// Try to open database and execute the update.
try
{
con.Open();
int updated = cmd.ExecuteNonQuery();
}
catch (Exception err)
{
Response.Write(err.Message);
}
finally
{
con.Close();
Response.Redirect("./?msg=eus");
}

Hi everyone!I have a update query which all looks good and it looks like it executes, though it does not effect the database for some unknown reason. (No error messages).protected void Button1_Click(object sender, EventArgs e)
{
int areaId = 0;
if (Request.QueryString["doc_area_id"] != null)
{
areaId = Convert.ToInt32(Request.QueryString["doc_area_id"]);
}
SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["CPS_docshareConnectionString"].ConnectionString);
SqlCommand command = new SqlCommand("UPDATE document_area SET doc_area_name = '" + AreaText.Text + "' WHERE doc_area_id = @areaId", myConnection);
command.Parameters.Add(new SqlParameter("@areaId", areaId));
myConnection.Open();
command.ExecuteNonQuery();
myConnection.Close();
} Thanks for any help you can give, cheers, Mark.

I am using the update query listed below in my DetailsView. The issue i am having is the ManagerDecision value which gets populated in a DropDownList in EditTemplate, doesnt seem to update correctly. If I choose 'Approved' from the DropDownList, the result for Status_Type ends up being 'Closed' and not 'Open'. Could someone please Help.
Thanks!!
UPDATE ServiceRequest_Table SET ManagerDecision = @ManagerDecision, Comments = @Comments, Priority_Name = @Priority_Name, Status_Type = CASE WHEN (ManagerDecision = 'Approved') THEN 'Open' ELSE 'Closed' END, ManagerDateTime = CASE WHEN (Status_Type = 'Closed') THEN '' END, Closed_Date = CASE WHEN (Status_Type = 'Open') THEN '' END WHERE (ServiceRequest_ID = @ServiceRequest_ID)
