How do I enable editing for grid view?

Posted 26 February 2008 - 03:11 PM

(mod can move this to asp.net forum, my bad)
So all I am trying to do is enable editing for one of my GridView database so I can have "staff" update and edit the database when need be. In my gridview source I added AutoGenerateEditButton=True. However its telling me I need my data source to have an update command enabled. How do I go about this?? Any helps would be awesome.

It looks to me like you simply need to tell the database what action to take when someone edits your grid.

You only have a SelectCommand described here. So when the grid tries to Update a row (which is what will happen if you edit it) it cannot find the right command. Try adding an UpdateCommand under your select command.

Hi,

When you are configuring the SqlDatasouce for programming datagrid in asp.net, sql server, you click on the advanced button and set option in Advanced SQL generation options. Then the code will be generated as shown below.


<div>
		<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FinAccountingConnectionString %>"
			DeleteCommand="DELETE FROM [AccountsTable] WHERE [AccountCode] = @AccountCode"
			InsertCommand="INSERT INTO [AccountsTable] ([AccountCode], [AccountName], [AccountDescription]) VALUES (@AccountCode, @AccountName, @AccountDescription)"
			SelectCommand="SELECT [AccountCode], [AccountName], [AccountDescription] FROM [AccountsTable]"
			UpdateCommand="UPDATE [AccountsTable] SET [AccountName] = @AccountName, [AccountDescription] = @AccountDescription WHERE [AccountCode] = @AccountCode">
			<DeleteParameters>
				<asp:Parameter Name="AccountCode" Type="String" />
			</DeleteParameters>
			<UpdateParameters>
				<asp:Parameter Name="AccountName" Type="String" />
				<asp:Parameter Name="AccountDescription" Type="String" />
				<asp:Parameter Name="AccountCode" Type="String" />
			</UpdateParameters>
			<InsertParameters>
				<asp:Parameter Name="AccountCode" Type="String" />
				<asp:Parameter Name="AccountName" Type="String" />
				<asp:Parameter Name="AccountDescription" Type="String" />
			</InsertParameters>
		</asp:SqlDataSource>
