        if (e.Row.RowType == DataControlRowType.DataRow)
        {
         string times= ((Label)e.Row.FindControl("lbltime")).Text;
 //string times= e.Row.Cells[columnIndex].Text;
       
          sum += (TimeSpan)times ;

Hi Praveen,

TimeSpan sum = TimeSpan.Zero;
for ( int i = 0; i < gridview1.Rows.Count; i++ )
{
   sum += (TimeSpan)gridview1.Rows[i].Cells[7].Text;
}
