Hi,

that is a bug of the GridView .

 

you can try :

 

protected override void OnInit(EventArgs e)
 {
  base.OnInit(e);
  GridView1.RowCreated+=new GridViewRowEventHandler(GridView1_RowCreated);
 }
 protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
 {
  if (e.Row.RowIndex == -1) return;
  e.Row.ID = "Row" + e.Row.RowIndex;
 }

 

Regards,

Terry
