Valore della proprietà

DataGrid.HitTestType

Una delle enumerazioni DataGrid.HitTestType.

Esempio

Nell'esempio seguente viene stampata la parte selezionata della griglia chiamando il HitTest metodo dall'interno dell'evento MouseDown di un System.Windows.Forms.DataGrid controllo . Questa operazione restituisce un oggetto 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.   
      switch ( hit )
