protected void GridView1_RowDataBound ( object sender, GridViewRowEventArgs e )
{
if ( e.Row.RowType == DataControlRowType.DataRow )
{
if ( e.Row.RowType == DataControlRowType.DataRow )
{
e.Row.Attributes.Add ( "onmouseover", "this.savedColor=this.style.backgroundColor;this.style.backgroundColor='Yellow'" );
