Hi,

I've pasted my code below. I need to know which row caused the itemcommand server side. This works fine in below code as long as the OnCommand client event is not used. When i start using it the ItemIndex is always 0. The same issue is described in http://www.telerik.com/community/forums/aspnet-ajax/grid/itemcommand-why-is-my-itemindex-always-zero.aspx, but the solution does not work for me as the selected row might be different. GetDataKeyValue also does not work it always returns the data key from first row.

Is there a way to find which row caused the itemcommand while have the client side OnCommand?

Thanks!

Hi,

Since you have client OnCommand handler attached, your server ItemCommand is always fired by first item in Items collection. This behavior appear only when you have custom CommandName/CommandArguments set. In order to get real Item on server ItemCommand event you can use the code below.

C#:

protected void rg_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "test")

{

GridDataItem item = RadGrid1.Items[e.CommandArgument.ToString()];

int Id = (int)item.GetDataKeyValue("a");

}

Thanks,
