Retrieving Selected Gridview Column Values For SQLDatasource Asp:controlparameters
Jun 12, 2006Not sure if this is the correct forum, but I 'm having problems retrieving a sqldatasource's asp:control parameter values from a selected row (during edit) in a gridview to update a record thru a stored procedure. The stored procedure is pretty intense, so I'd like to keep it in SQL if possible instead of creating the generic "update table set ..." that I see in most examples. It seems as if I can't get the propertyname right or something because it keeps giving me a "Procedure or function XX has too many arguments specified error". Maybe the DataKeyNames is not right?? I've tried just passing one parameter (ProductID-same as DataKeyNames) using "SelectedValue" as propertyname and still get the same. It's got to be something very simple, but I'm at a loss. All parameters are spelled the same in the sp (with an added "@" at start) as in the asp:controlparameters. Here's the gridview (asp.net 2.0 connecting to SQL Server 2005):
<asp:GridView ID="gvLoadEditProductPrices" runat="server" AutoGenerateColumns="False" AllowSorting="True" DataSourceID="SqlDataSource1" DataKeyNames="ProductID">
<Columns>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="ProductID" HeaderText="ProductID" HeaderStyle-BackColor="white" InsertVisible="False"
ReadOnly="True" SortExpression="ProductID" />
<asp:BoundField DataField="Product" HeaderText="Product" SortExpression="Product" ReadOnly="True" />
<asp:BoundField DataField="ProductCat" HeaderText="ProductCat" SortExpression="ProductCat" ReadOnly="True" />
<asp:BoundField DataField="VarRate" HeaderText="VarRate" SortExpression="VarRate" />
<asp:BoundField DataField="loadid" HeaderText="loadid" InsertVisible="False" ReadOnly="True"
SortExpression="loadid" />
<asp:BoundField DataField="loadamount" HeaderText="loadamount" SortExpression="loadamount" ReadOnly="True" />
<asp:BoundField DataField="ProductCol" HeaderText="ProductCol" SortExpression="ProductCol" ReadOnly="True" />
<asp:BoundField DataField="PageID" HeaderText="PageID" SortExpression="PageID" ReadOnly="True" />
</Columns>
</asp:GridView>
and the sqldatasource's info:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:MARSProductEditor %>" ProviderName="System.Data.SqlClient" SelectCommand="spGetLoadEditProductPrices" SelectCommandType="StoredProcedure" UpdateCommand="spUpdateProductPrices" UpdateCommandType="StoredProcedure" >
<UpdateParameters>
<asp:ControlParameter Name="ProductID" Type="Int32" ControlID="gvLoadEditProductPrices" PropertyName=SelectedDataKey.Values("ProductID")></asp:ControlParameter>
<asp:ControlParameter Name="LoadID" Type="Int32" ControlID="gvLoadEditProductPrices" PropertyName=SelectedDataKey.Values("LoadID")></asp:ControlParameter>
<asp:ControlParameter Name="PageID" Type="Int32" ControlID="gvLoadEditProductPrices" PropertyName=SelectedDataKey.Values("PageID")></asp:ControlParameter>
<asp:ControlParameter Name="ProductCol" Type="Int32" ControlID="gvLoadEditProductPrices" PropertyName=SelectedDataKey.Values("ProductCol")></asp:ControlParameter>
<asp:ControlParameter Name="NewRate" Type="Double" ControlID="gvLoadEditProductPrices" PropertyName=SelectedDataKey.Values("NewRate")></asp:ControlParameter>
</UpdateParameters>
<SelectParameters>
<asp:ControlParameter ControlID="ddlEstLoadsPerAcre" Name="LoadID" PropertyName="SelectedValue"
Type="Int32" />
<asp:ControlParameter ControlID="txtEditType" Name="PageName" PropertyName="Text"

</SelectParameters>

ASP: SqlDataSource - Select Command
Aug 10, 2007I am using <asp:SqlDataSource ID and for the Select Command, the following, where the WHERE clause ... for an exact match (=) works correctly:
SelectCommand="SELECT [PatientID], [MedRecord] , [Accession], [FirstName], [LastName], [Address1] FROM [ClinicalPatient] WHERE (LastName = @LastName) ORDER BY [LastName]DESC">
I would like to do a "LIKE" search where the LastName Parameter is matched using "LIKE". In this situation how would the syntax be written.... I tried:
LastName LIKE '%" & LastName & "%'"
But I get an error???? Any suggestions, please...
Thanks !!
SqlDataSource Select Command
Nov 15, 2007I have a SqlDataSource object that is bound to a GridView control. I have configured the SqlDataSource with a default select command. Under certain values of query strings on the URL for this page (Default.aspx), I want to change the select command. So I put the statements in the Page_Load method for Default.aspx to define SqlDataSource1.SelectCommand. The changed SelectCommand works fine for the first page of GridView data and shows 5 GridView pages, but if I switch to one of the other pages, it seems to revert to the default SelectCommand (which generates 19 GridView pages). I assume I should put my code to change the SelectCommand somewhere else. Can someone help me with where to put it? Thanks!

Dynamic SELECT Command In SqlDataSource
Jul 20, 2007I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid. I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e. SelectCommand="usp_reports_shortages" to "usp_reports_shortagesbyID" and "usp_reports_shortagesbyDate" depending on the value selected in the dropdownlist. So, is there any way to do this????<asp:SqlDataSource ID="SqlDataSource1"
runat="server"
ConnectionString="<%$
ConnectionStrings:TESTDrivercommunication %>"
SelectCommand="usp_reports_shortages" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ControlParameter ControlID="lblDriver" Name="date1" PropertyName="Text" Type="DateTime" />
<asp:ControlParameter ControlID="lblTODate" Name="date2" PropertyName="Text" Type="DateTime" />
<asp:ControlParameter ControlID="DDlDriver" Name="driver" PropertyName="SelectedValue"
Type="Int32" />

Dynamic SqlDataSource Select Command?
Apr 25, 2008I am trying to implement an "advanced search" feature on my ASP.NET 2.0 web form. I have a GridView control and a SqlDataSource. The SqlDataSource control successfully retrieves data when the SelectCommand attribute is set in the aspx page. I need to make it so when a user clicks on a button, it can take a value from a text box and use it in the WHERE clause. I have tried setting the SelectCommand programmatically and then DataBinding but it never accepts the new SelectCommand. What can I do to fix this?
View 5 Replies View RelatedSqlDataSource And SSMSE Returning Different Results For Same SELECT Command
Oct 2, 2007Hi,
Hope you guys won't mind this rather newbie question. I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table). The SqlDataSource control is:
<asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource>
This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table. However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get)
HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query:
blogID, title, description, tags, dateAdded, noOfComments
1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0
Can anyone help? The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row). Many thanks for any suggestions!

I am having problem to insert the record into database from sqldatasource control. my code is listed below, and i can't find anything why it cause the exception...

The table has got the fields that needed for insert command, for example:

And in the code i just called: SqlDataSource1.Insert(); Then the page gives me the exception like:
Cannot insert the value NULL into column 'STATE', table 'WebsiteData.dbo.ServiceAgents'; column does not allow nulls. INSERT fails. The statement has been terminated.
But i actually input all the required text in the textbox.... Any idea guys?

Using @@IDENTITY In The Sqldatasource Insert Command
Jan 11, 2008I apologise if i have not posted this in the correct Topic before i start. But was uncertain where to post this query.
This is my first project in ASP.NET, MS Visual Web Developer 2005 Express and SQL Server 2005 Express. I have relatively little experience, so please bare with me.
I have managed to create a form that inserts data into a table and then inserts the Automatically Created Primary Key(as a foreign key) in another table. I have done this by inserting what is highlighted in red in the code of my InsertCommand below (Please scroll across to the end of the code):-InsertCommand="INSERT INTO [PrinterModel] ([Model], [PrinterMakeID], [CartridgeCode], [PartCode], [Duplex], [NIC], [Wireless], [Parallel], [USB], [Colour], [PrinterTypeID]) VALUES (@Model, @PrinterMakeID, @CartridgeCode, @PartCode, @Duplex, @NIC, @Wireless, @Parallel, @USB, @Colour, @PrinterTypeID) INSERT INTO [Model] ([PrinterModelID],[TypeID]) VALUES (@@IDENTITY, 3)" Can you see any problems that may arise from using this method. This project is an Asset Management System and will be used by no more than a handful of users. My Concern is the use of the @@IDENTITY (As it only stores the last Key used). Should I be using it here? If there is more than one user inserting into tables (Chances of this happening are very low), will the correct Primary key be insert to the table in the above code?Thank you for your comments.

Passing '% Variable %' To SqlDataSource Through E.Command.Parameters
Feb 23, 2008Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

Setting SqlDataSource Update Command And Parameters Dynamically C#
Aug 31, 2007Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">

Multiple SqlDataSource On A Page
Nov 26, 2006Hi,
I placed several SqlDataSource objects on my page which work with the same database (same connection string).
As I know, connection operation to database is costly in the performance prespective.
Do these SqlDataSource controls work with the same connection object or each of them create his own connecton object?
If each create it's own, then can they be changed to work with one connection object?
Thanks
Sqldatasource Multiple Insert
Oct 8, 2007Hi all,
I have few insertions statements in one datasource insert command, which i use for my user creation process adding new billing info shipping info and so on.
I've put this code in createuserwizard usercreated step with a try catch code. On the insertion if it doesnt work it deletes the user account.
Well lets say the first insertion went trough with out any problems, but the second one got blocked or didnt work length or any wierd on controled issue.
I was thinking of putting begin transaction end transaction statements in front and end of the statements but this can prevent the insert not to return error, which will prevent try catch to fire?
Basicly the idea is to do all insertions with the user creation, and if one goes down all the others gets reversed. (if possible single sqldatasource, just to make the code look clean)
Can Multiple Selection Controls Be Use With SqlDataSource?
Mar 4, 2007 NET 2.0
I am using Visual Studio Express 2005 for database web developement.
I have created a database with 5 tables. Two are associative tables.
They are
SoftwarePK SoftwareID Title
SoftwareSolutionFK SoftwareIDFK SolutionID
SolutionPK SolutionID Title
CategorySolutionFK CategoryFK Solution
Category
PK Category Title
Criteria for a search with three sources of input into a SqlDataSource attached to a FormView for paged out.
The following are the Search Criteria input sources:1) ListBox in Multiple Selection Mode2) CheckBoxList with Mutiple checks posible2) TextBox with key word search in Title.
Each Solution has 0 or many Categories and 0 or many Software.
When the records are entered in the database, the associative information for Categories and Software are populated to filter thereturned values.
In NET 1.1, I would create a search string like the following in code behind by looping through the CheckBoxList and ListBox finally adding the TextBox:
SELECT Solution.SolutionID, Solution.Title FROM SolutionWHERE Solution.SolutionID IN ('2','3','5') AND Solution.Title LIKE '%Math%'
I am unable to update the SelectCommand in the ASPX page.
However, when I use the I have used theSystem.Web.UI.WebControls.SqlDataSources"SelectQuery Builder"I receive the following in the Source for ASPX: <asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT Solution.SolutionID, Solution.Title
FROM
Solution INNER JOIN CategorySolution ON Solution.SolutionID = CategorySolution.SolutionID
INNER JOIN SoftwareSolution ON Solution.SolutionID = SoftwareSolution.SolutionID">
<SelectParameters>
<asp:ControlParameter ControlID="CheckBoxList1" DefaultValue="%" Name="CategoryID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="ListBox1" DefaultValue="%" Name="SoftwareID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="txtTitleSearch" DefaultValue="%" Name="Title" PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource> I receive duplicate records and not sure if the code generated accesses the Mutiple Selected values in the CheckBoxList1 and ListBox1.Question: 1) If the SelectQuery generator will not access multiple selected values from the CheckBoxList1, how can I use code behind to replaceSelectCommand in the ASPX page?2) What is the best solution for using the CheckBoxList1, ListBox1, and TextBox for filtering my results? Sample code, references to solutions, corrections on logic, a new approach, how to use the wizard correctly would all be greatly appreciated.3) Can Multiple Selection Controls be use with a SqlDataSource SELECT Command?Thanks for your time,Sincerely,Unhistoric
Multiple SqlDataSource Controls On A Page
Jun 8, 2007Thanks for your help.
I'm just getting into ASP.NET 2.0 and started using the SqlDataSource control to declaritively connect to a database. I was wondering if I have two SqlDataSource controls on one page with two select commands querying the same database, will the that create to seperate instances of opening and closing the connection to the database, or will it open the database once, execute both queries, and then close the connection. It seems that if it creates two separate connections, it would still be more efficient to to connect to the database programmatically using ADO.NET. You would only need to make one trip to the database, pull down all of your data, and then close the connection.

SqlDataSource And Passing Multiple Int Parameters In Query
Aug 11, 2007Hi All,
View 2 Replies View RelatedChanging Parameter In SQLDataSource For Multiple DropDowns
Aug 29, 2007I have one page, one connection, and three dropdowns. The connection looks like (as an example):<asp:SqlDataSource ID="DropDownConn" runat="server" ConnectionString="<%$ ConnectionStrings:aousConnectionString %>" SelectCommand="SELECT [Value], [Text] FROM [DropDown] WHERE (([Group] = @Group) AND ([Viewable] = @Viewable))"> <SelectParameters> <asp:Parameter Name="Group" Type="String" /> <asp:Parameter DefaultValue="True" Name="Viewable" Type="Boolean" /> </SelectParameters></asp:SqlDataSource>
The DropDowns Look like this:
<asp:DropDownList ID="DropDown1" runat="server"></asp:DropDownList><asp:DropDownList ID="DropDown2" runat="server"></asp:DropDownList><asp:DropDownList ID="DropDown3" runat="server"></asp:DropDownList>The C# Code I am trying is like this:DropDownConn.SelectParameters["Group"].Equals("DropDown1");DropDownConn.SelectParameters["Viewable"].Equals(true);DropDown1.DataSourceID = "DropDownConn";DropDown1.DataTextField = "Text";DropDown1.DataValueField = "Value";DropDown1.DataBind();
As an example. I can not get it done so that I don't have to create 3 dataconnections. Any help, PLEASE?
Of Multiple Parameters, SqlDataSource And Text Boxes
Feb 12, 2006Hi,Hope if someone can help me here. Keep in mind I an fairly new to .NET and SQL and am learning to break my MS Access habit :)
I have a web form that is using a SqlDataSource and a FormView control. In addition to this I have 2 text boxes. What I am trying to do is display results in the FormView based on what a user types into one of the Text Boxes (one or the other…Not both)
The SELECT statement in the SqlDataSource looks like this in concept.
SELECT Field1, Field2, Field3, Field4FROM dbo.MYTABLEWHERE (Field1 = @Field1) AND (Field2 IS NULL)OR (Field2 = @Field2) AND (Field1 IS NULL)
I have the two text boxes pointing at the parameters (@Field1 and @Field2) so in theory I would expect that when a user populates one of the text boxes and clicks a button to databind the FormView it would display a record matching that criteria…. But it’s not all I get is a blank/missing FormView.
I tried different variations on the SQL statement and tried using = '' instead of IS NULL but still the same results. However, if I populate one text box with a value that I know is not in my table and populate the other with a value of which I know exists in my table is…It works.What am I missing?
