Deleting And Updating From Gridview
Nov 10, 2007
Hi,
I made a gridview, and I am trying to make it so when the user deletes a row, values in other tables update. I used the following source code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
DeleteCommand="DELETE FROM [Transactions] WHERE [TransactionID] = @TransactionID AND UPDATE [items] SET Quantityavailable, numtaken VALUES Quantityavailable + 1, numtaken - 1 WHERE ([Itemid] = @Itemid) "
It gives the error that Quantityavailable is not a SET type?
Thanks if you can suggest a remedy!

I am trying to do something that I would think is simple. I have a stored procedure used for deleting a record, and I want to call it from the "Delete" command of a Delete button on a GridView. This incredible simple SP accepts one value, the unique record ID to delete the record like this:CREATE PROCEDURE usp_DeleteBox
/* *******************************************
Delete a record using the Passed ID.
********************************************** */
(
@pID as int = Null
)
AS
DELETE FROM [Boxes]
WHERE ID = @pID
When I configured the data source for the GridView, I selected the "Delete" tab and selected my Stored Procedure from the list. As mentioned on another post I saw here, I set the "DataKeyNames" property of the GridView to my id field (called "ID", naturally).
When I click the Delete button on a row, I get this error message: "Procedure or function usp_DeleteBox has too many arguments specified." If I leave the "DataKeyNames" property empty, it does nothing when I click delete.
Can someone tell me the correct way to configure this? I am sure I am missing something obvious, and I would appreciate any suggestions. Thank you!

Hi,
I've got a gridview that displays some (but not all) columns from a sql database table. One of the columns that is NOT displayed is the table's primary key column. I'm putting together this row updating sub based on an article I found on the 'Net. Here's the code I've added for the GridView's edit routine (based on the article):Protected Sub gvPersonnelType_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvPersonnelType.RowEditing
gvPersonnelType.EditIndex = e.NewEditIndex
gvPersonnelTypeBindData()
End Sub
Protected Sub gvPersonnelType_RowCancellingEdit(ByVal sender As Object, ByVal e As GridViewCancelEditEventArgs)
gvPersonnelType.EditIndex = -1
gvPersonnelTypeBindData()
End Sub
Protected Sub gvPersonnelType_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs)
'Dim PersonnelTypeID As Integer'This is not displayed in the gridview, but is the primary key in the database
Dim LaborForceTypeID As Integer
Dim DefaultPayRate, DefaultPieceRate, Rebill As Decimal'These are money datatype in the database
Dim DefaultAdminCostPercent, MarkUp As Double 'These are float datatype in the database'Don't know if the following lines properly "capture" the values in the textboxes
LaborForceTypeID = Integer.Parse(gvPersonnelType.Rows(e.RowIndex).Cells(0).Text)
DefaultPayRate = CType(gvPersonnelType.Rows(e.RowIndex).Cells(1).Controls(0), TextBox).Text
DefaultPieceRate = CType(gvPersonnelType.Rows(e.RowIndex).Cells(2).Controls(0), TextBox).Text
DefaultAdminCostPercent = CType(gvPersonnelType.Rows(e.RowIndex).Cells(3).Controls(0), TextBox).Text
Rebill = CType(gvPersonnelType.Rows(e.RowIndex).Cells(4).Controls(0), TextBox).Text
MarkUp = CType(gvPersonnelType.Rows(e.RowIndex).Cells(5).Controls(0), TextBox).Text
Dim gvSqlConn = New SqlConnection("DATABASECONNECTION")
gvSqlConn.open()
Dim UpdatePersonnelTypeCmd As New SqlCommand("UPDATE rsrc_PersonnelType SET LaborForceTypeID = @LaborForceTypeID, " & _
"DefaultPayRate = @DefaultPayRate, DefaultPieceRate = @DefaultPieceRate, " & _
"DefaultAdminCostPercent = @DefaultAdminCostPercent, Rebill = @Rebill, Markup = @Markup", gvSqlConn)
'Sql doesn't know what row to update: NEED WHERE STATEMENT!!!
UpdatePersonnelTypeCmd.Parameters.Add(New SqlParameter("@LaborForceTypeID", LaborForceTypeID))
UpdatePersonnelTypeCmd.Parameters.Add(New SqlParameter("@DefaultPayRate", DefaultPayRate))
UpdatePersonnelTypeCmd.Parameters.Add(New SqlParameter("@DefaultPieceRate", DefaultPieceRate))
UpdatePersonnelTypeCmd.Parameters.Add(New SqlParameter("@DefaultAdminCostPercent", DefaultAdminCostPercent))
UpdatePersonnelTypeCmd.Parameters.Add(New SqlParameter("@Rebill", Rebill))
UpdatePersonnelTypeCmd.Parameters.Add(New SqlParameter("@Markup", MarkUp))
UpdatePersonnelTypeCmd.ExecuteNonQuery()
gvSqlConn.close()
gvPersonnelType.EditIndex = -1
gvPersonnelTypeBindData()
End Sub
As you can see, I've added some notes in the RowUpdating sub. I don't understand how to use the PersonnelTypeID (the database table's primary key) for the WHERE clause to update the correct row in the database.
As for the GridView itself, it's populated from the code-behind as well (as you can see from the call to "gvPersonnelTypeBindData()") and the SELECT statement used to populate the gridview doesn't use the PersonnelTypeID column either.
I'd appreciate it if someone could point me in the right direction to get this RowUpdating sub working.
Thanks!

Hi - Once again I've been looking at this forever and not able to see the problem. Have a grid table everything updates except the training date field. That get's wiped out each time - no matter if something is in it or not. Everything else updates correctly.
Here's the code:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="ds1" DataKeyNames="eventID"><Columns><asp:CommandField ButtonType="Button" ShowEditButton="True" ShowDeleteButton="True" /><asp:BoundField DataField="eventID" HeaderText="ID" SortExpression="eventID" ReadOnly="True"><HeaderStyle Font-Bold="True" Font-Names="Verdana" Font-Size="Small" /><ItemStyle Font-Names="Verdana" Font-Size="Small" /></asp:BoundField><asp:TemplateField HeaderText="Training Date" SortExpression="trainingDate"><EditItemTemplate><asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("trainingDate", "{0:M/dd/yy}") %>'></asp:TextBox></EditItemTemplate><ItemTemplate><asp:Label ID="Label1" runat="server" Text='<%# Bind("trainingDate", "{0:M/dd/yy}") %>'></asp:Label></ItemTemplate><HeaderStyle Font-Bold="True" Font-Names="Verdana" Font-Size="Small" /><ItemStyle Font-Names="Verdana" Font-Size="Small" /></asp:TemplateField>
<asp:SqlDataSource ID="ds1" runat="server" ConnectionString="<%$ ConnectionStrings:TrainingClassTrackingConnectionString %>" ProviderName="<%$ ConnectionStrings:TrainingClassTrackingConnectionString.ProviderName %>"UpdateCommand="UPDATE [trainingLog] SET [trainingDate] = @trainingDate WHERE [eventID] = ?" >

Hi, I'm new in ASP 2.0. I need to incorporate edit and delete capability in GridView. Using the wizard, i've generated this code. When I delete a row, it gets deleted but update does not work. I've tried several ways. I got no error or exception. But row is not updated. I've checked database, and I think the update query is not executing at all. Please let me know, what I'm doing wrong? Here is the source code for reference. I'm using Visual Studio 2005 with SQL server 2005 Express Edition. Regards
==========================================================

Hi all,I have a gridview that bound to a SqlDataSource called SqlDataSourceGridView. I have enabled Edit in my GridView, but I do all the updating in code behind with stored procedure (using onRowUpdating). Now each time when I click "Update", the update went through and all the data got updated, but I received this error: Updating is not supported by data source 'SqlDataSourceGridView' unless UpdateCommand is specified.
Description: An
unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the
error and where it originated in the code.
Exception Details: System.NotSupportedException:
Updating is not supported by data source 'SqlDataSourceGridView' unless

Hi,
I'm using ASP with a JScript variant and MSSQL Server 2000. I would like to write a script that basically erases all data except for a few things.
Is there a way to update multiple tables at once without having to write lines and lines of code? I tried UPDATE tbl1,tbl2 SET uid='asc', but to no avail. It gave me a syntax error. My thinking behind it is something like... UPDATE dbo.* SET uid='mferguson' and after that I can delete stuff like DELETE dbo.*... Any ideas?
I know the above is ASP, I've tried this thread in the ASP forum with no avail... they referred me to this forum.

I have created a single Data Flow Task that reads a set of records from a source table and then makes determinations whether to insert, update or delete from a destination table. The data is basically being copied from one database to another with a small amount of data manipulation and lookups. The problem seems to be that when running the task, even a small amount of records read from the source table seem to take a long time for the task to finish. I feed the records into a Script Component (the brains) that sorts the records to three separate outputs. I use OLE DB Commands to perform the DELETE and UPDATE and an OLE DB Destination for INSERT. I thought that by using three separate database connections would help, but it just appears to be locked while trying to perform these commands against the same table.
Is there a way to control or route these three record sets in such a way as to perform them sequentially?
I know it's a bit of a simple question for some of you, but I'm just learning SSIS (but I like it!).
Thanks!

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!

I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..

I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?

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>

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" />

I have a gridview that has AllowSorting="true" however I need to implement my own sorting because I have DateTime and Integer data types in several of the columns and I don't want an int column sorted like 1,12,2,23,3,34,4,45,5,56, etc. So, I've added SortParameterName="sortBy" and adjusted my stored procedure to accept this. For only ASC sorting, I've got
ORDER BY CASE WHEN @sortBy='' THEN DateCreated END, CASE WHEN @sortBy='DateCreated' THEN DateCreated END
and so on. However, columns can also be sorted with DESC. I tried CASE WHEN @sortBy='DateCreated DESC' THEN DateCreated DESC END, but I get a syntax error on DESC. How can I do this?

Hello:I have add a DropDownList to my GridView and binded the dropdownlist to a field from a select statement in the SQLDataSource. I have EnabledEditing for my GridView. The GridView is populated with information from the select statement. Some of the information returned from the select statement is null. The field where the dropdownlist is binded it is null in some cases and does not have a value that is in the dropdownlist so I get and error when I attempt to do an update. 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value Is there a way to get around this besides initializing all the columns in the table that are going to be binded to a dropdownlist to a value in the dropdownlist?

I have a simple gridview displaying data from an MSSQL server 2005. Every now and then I get a sql timeout error. Listed below. Can anyone explain why I am getting this error? The connection pool is 100 and the timeout is set to 360. I have checked to current connections in SQL and they never max over 23. There are not locks in SQL when the problem occurs.

Hey guys, Am in need of help please, basically the program im working with at the moment is when you add a New Contract, it will grab the Contract Number you have entered, Post it over to another page, then using that number bind a Gridview. The SQL being "SELECT Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent FROM ECS_Contracts_Test WHERE Contract_Number = " & conNoVar (this being the Contract Number of the recently added Contract), however then it comes to Bind the Grid it kicks up an System.Data.SqlClient.SqlException: Syntax error converting the nvarchar value
'2009P7899' to a column of data type int.But the Column Contract_Number is set to Varchar and all I really want to do is to create this gridview using this criteria and not convert anything! The Contract_ID is an int, which is needed as I increment it. Heres the error code: Public Sub BindtheGrid()'Bind the Contract Grid, where ContractID is used
Dim SQL As String = "Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent"
Dim objConn As SqlConnection = New SqlConnection(ConnectionString)
Dim cmdstock As SqlCommand = New SqlCommand("SELECT " & SQL & " FROM ECS_Contracts_Test WHERE Contract_Number = " & contractQueryID, objConn)
cmdstock.CommandType = CommandType.Text
objConn.Open()
GridView1.DataSource = cmdstock.ExecuteReader()
GridView1.DataBind()
objConn.Close()
End Sub If you need any more information then please let me know. Mucho Aprreciated

I have created a GridView that uses a SqlDataSource. When I run the page it does not pull back any data. However when I test the query in the SqlDataSource dialog box it pulls back data.
Here is my GridView and SqlDataSource:
<asp:GridView ID="Results" runat="server" AllowPaging="True" AllowSorting="True"
CellPadding="2" EmptyDataText="No records found." AutoGenerateColumns="False" Width="100%" CssClass="tableResults" PageSize="20" DataSourceID="SqlResults" >
<Columns>
<asp:BoundField DataField="DaCode" HeaderText="Sub-Station" SortExpression="DaCode" >
<ItemStyle HorizontalAlign="Center" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Center" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="DpInfo" HeaderText="Delivery Point" SortExpression="DpInfo" >
<HeaderStyle HorizontalAlign="Left" CssClass="tdHeaderResults" />
<ItemStyle CssClass="tdResults" />
</asp:BoundField>
<asp:HyperLinkField DataNavigateUrlFields="CuCode,OrderID" DataNavigateUrlFormatString="TCCustDetail.asp?CuCode={0}&OrderID={1}"
DataTextField="OrderID" HeaderText="Order No" SortExpression="OrderID">
<ItemStyle CssClass="tdResults" HorizontalAlign="Center" />
<HeaderStyle CssClass="tdHeaderResults" HorizontalAlign="Center" />
</asp:HyperLinkField>
<asp:BoundField HeaderText="Order Date" SortExpression="OrderDate" DataField="OrderDate" >
<ItemStyle HorizontalAlign="Center" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Center" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="ReqDeliveryDate" HeaderText="Req Delivery Date" SortExpression="ReqDeliveryDate" >
<ItemStyle HorizontalAlign="Center" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Center" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="StatusDate" HeaderText="Status Date" SortExpression="StatusDate">
<ItemStyle HorizontalAlign="Center" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Center" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="ManifestNo" HeaderText="Manifest No" SortExpression="ManifestNo">
<ItemStyle HorizontalAlign="Center" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Center" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="CustomerPO" HeaderText="P.O. No" SortExpression="CustomerPO">
<ItemStyle HorizontalAlign="Center" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Center" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="Class" HeaderText="Class" SortExpression="Class">
<ItemStyle HorizontalAlign="Left" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Left" CssClass="tdHeaderResults" />
</asp:BoundField>
<asp:BoundField DataField="OrderStatus" HeaderText="Order Status" SortExpression="StatusSort">
<ItemStyle HorizontalAlign="Left" CssClass="tdResults" />
<HeaderStyle HorizontalAlign="Left" CssClass="tdHeaderResults" />
</asp:BoundField>
</Columns>
<HeaderStyle ForeColor="White" HorizontalAlign="Left" />
<AlternatingRowStyle CssClass="tdResultsAltRowColor" />
</asp:GridView>
<asp:SqlDataSource ID="SqlResults" runat="server" ConnectionString="<%$ ConnectionStrings:TransportationConnectionString %>" SelectCommand="GetOrderSummaryResults" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter DefaultValue="10681" Name="CuCode" Type="String" />
<asp:Parameter DefaultValue="" Name="DaCode" Type="String" />
<asp:Parameter DefaultValue="" Name="DpCode" Type="String" />
<asp:Parameter DefaultValue="" Name="OrderID" Type="String" />
<asp:Parameter DefaultValue="" Name="ManifestNo" Type="String" />
<asp:Parameter DefaultValue="" Name="PONo" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
I can get it to fill with data by manually filling the GridView without using a SqlDataSource but then I cannot get the sorting to work when I do it that way. Actually not sure if the sorting will work this way either as I cannot get it to fill with data. Any ideas would be much appreciated.

Sqldatasources are used for a dropdownlist and a gridview. How can the dropdownlist selection refresh the gridview? This is done programmatically in ASP.NET 1.1 code behind. Can it be done in ASP.NET 2.0 without code behind? Thanks.

Where exactly are the updateparameters of a gridview picked up from? I have created 2 very similar gridviews and given the updateparameters the same names as in my edititemtemplates. Yet this method has worked for 1 gridview and failed for the second gridview. Here is my gridview :
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:XConnectionString %>" SelectCommand="ViewForecast" SelectCommandType="StoredProcedure" DeleteCommand="DeleteForecast" DeleteCommandType="StoredProcedure" UpdateCommand="UpdateForecast" UpdateCommandType="StoredProcedure"> <DeleteParameters> <asp:Parameter Name="ForecastKey" Type="Int32"

And here is my stored proc :
CREATE procedure dbo.UpdateForecast
( @ForecastKey int, @CompanyKey bigint, @ForecastType char(1), @MoneyValue float, @ForecastPercentage float, @DueDate datetime, @UserKey int)
as
update Forecastset CompanySiteKey = @CompanyKey,MoneyValue = @MoneyValue,Probability = @ForecastPercentage,ForecastType = @ForecastType,InvoiceDate = @DueDate,UserKey = @UserKeywhere ForecastKey = @ForecastKeyGO
Can anybody with more experience of using gridview please tell me where I am going wrong?
Cheers,
Mike
