AutoGenerateColumns="False" OnRowCommand="gvstaff_RowCommand" Width="100%" DataKeyNames="bigint_StaffId">

<%# DataBinder.Eval(Container.DataItem,"NoOfAscents") %>

COde:

GridViewRow row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
int DemoId = Convert.ToInt32(gvdemo.DataKeys[row.RowIndex].Value);
//You will get id here.....You code goes Here....
}
else if (e.CommandName == "Select1")

Hi, I have found out that if you have a ButtonField with the ButtonType set to image within a GridView the RowCommand Event fires twice or sometimes more. The problem lies with Internet Explorer, to solve the problem I have used Template Fields instead.
