protected void GridView2_RowDataBound1(object sender, GridViewRowEventArgs e)
{
    :
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
    for (int i = 0; i < e.Row.Cells.Count; ++i)
    {
         LinkButton myButton = new LinkButton();
         myButton.Text = "○";
         myButton.DataBinding += new EventHandler(TemplateControl_DataBinding);
         e.Row.Cells[i].Controls.Add(myButton); 
    }
  }
}
private void TemplateControl_DataBinding(object sender, System.EventArgs e)
{
     LinkButton lb = (LinkButton)sender;
