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

private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
  {
   ListItemType lit = e.Item.ItemType;
   if (lit == ListItemType.Item || lit == ListItemType.AlternatingItem)
   {
    ModufyItem(e);
   }
  }

  private void ModufyItem(DataGridItemEventArgs e)
  {
   WebControl wc;
   int i = e.Item.Cells.Count -1;//here as the delete button is in the lastest cell
   wc = ((WebControl) e.Item.Cells[i]);

   wc.Height = 25;    //set the button style
   wc.Width = 50;
   String javascript = "return confirm('Delete it??');"; //here is the js to be added
   wc.Attributes.Add("onclick", javascript);
   wc.ToolTip = e.Item.Cells[2].Text.Trim() + "...";
   wc.ToolTip += "Delete this row";
  }
