It's a workaround, check if it helps you:
You can convert your existing BoundColumn to Linkbuton
if it is feasible with your requirement.
if( i==0)
{
LinkButton lnkbtn = new LinkButton();
lnkbtn.Text = e.Row.Cells[7].Text;
// Create a command button and link it to your id
// lnkbtn.CommandArgument = e.Row.Cells[0].Text; --Your Id
// lnkbtn.CommandName = "NumClick";
// btn.Text = "view more";
e.Row.Cells[7].Controls.Add(lnkbtn);
}
