      DataGrid^ grid = dynamic_cast<DataGrid^>(sender);
      hi = grid->HitTest( e->X, e->Y );

      // Test if the clicked area was a cell.
      if ( hi->Type == DataGrid::HitTestType::Cell )

         CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(this->BindingContext[ myDataSet->Tables[ dgt->MappingName ] ]);

         // Get the Rectangle of the clicked cell.
         Rectangle cellRect;
