Problem with DataGrid.ItemCommand Method

[James1981]

Hi,

I have a button in my datagrid, and an event handler for it which calls a function.. Only the eventhandler never calls the function, (or possibly the eventhandler never captures the button being pressed). Has any body had any similar problems or can anyone see any problems with my code:

Event Handler:

this.DataGrid1.ItemCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_ItemCommand);

My Method:

private void DataGrid1_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
		{			
			string myID = e.Item.Cells[2].Text;
   
			if (e.CommandName == "cancel")
			{
                           // Method here		
			}
			DataGrid1.DataBind();
		}

My DataGrid

<asp:ButtonColumn Text=&quot;Cancel&quot; ButtonType=&quot;PushButton&quot; HeaderText=&quot;Cancel&quot; CommandName=&quot;cancel&quot;>
  <HeaderStyle HorizontalAlign=&quot;Center&quot;></HeaderStyle>
  <ItemStyle HorizontalAlign=&quot;Center&quot;></ItemStyle>
</asp:ButtonColumn>

Thanks

James

You've specified a cancelCommand, not an itemCommand.

Cancel is a reserved command that has it's own event handler:

this.DataGrid1.CancelCommand

If you want to handle it as a regular flavored command, then assign "cancel" to the commandArgument, not the commandName... or handle it as a cancelCommand.

Either way.

Paul,

This turned out to be one issue, so thanks. However, another problem that was hidden; in the page load I was always rebinding the datagrid to the original data fetch. Instead I needed to implement a isPostBack test. This fixed this problem.

Cheers
