Declarare dr (Array of DataRow) outside that method.

DataRow[] dr;

 private void grdClientDetails_CellDoubleClick(object sender, FarPoint.Win.Spread.CellClickEventArgs e)
{
   dr = dsClientDetails.Tables[0].Select("ACCNUMBER=" + grdClientDetails.ActiveSheet.Cells[e.Row, 1].Text);
   this.Hide();           
}
 public DataRow[] dr {  get  {  return dr;   } }
