Ejemplos

En el ejemplo siguiente se imprime la parte en la que se hace clic en la cuadrícula llamando al HitTest método desde el MouseDown evento de un System.Windows.Forms.DataGrid control . Esto devuelve un objeto DataGrid.HitTestInfo.

private:
   void dataGrid1_MouseDown( Object^ /*sender*/,
      System::Windows::Forms::MouseEventArgs^ e )
   {
      String^ newLine = "\n";
      Console::WriteLine( newLine );
      System::Windows::Forms::DataGrid::HitTestInfo^ myHitTest;
      // Use the DataGrid control's HitTest method with the x and y properties.
      myHitTest = dataGrid1->HitTest( e->X, e->Y );
      Console::WriteLine( "Hit {0}", ReturnHitTest( myHitTest->Type ) );
   }

   String^ ReturnHitTest(
      System::Windows::Forms::DataGrid::HitTestType hit )
   {
      // Use this function to return the part of the grid clicked.
