Esempio

Nell'esempio seguente viene utilizzato il HitTest metodo in un MouseDown evento per restituire l'oggetto DataGrid.HitTestInfo . La riga, la colonna e la parte della griglia vengono quindi stampate.

private:
   void dataGrid1_MouseDown( Object^ /*sender*/, System::Windows::Forms::MouseEventArgs^ e )
   {
      Console::WriteLine();
      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( myHitTest );
      Console::WriteLine( "Column {0}", myHitTest->Column );
      Console::WriteLine( "Row {0}", myHitTest->Row );
      Console::WriteLine( "Type {0}", myHitTest->Type );
      Console::WriteLine( "ToString {0}", myHitTest );
      Console::WriteLine( "Hit {0}", myHitTest->Type );
   }

private void dataGrid1_MouseDown
(object sender, System.Windows.Forms.MouseEventArgs e)
{
   Console.WriteLine();
   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(myHitTest);
   Console.WriteLine("Column " + myHitTest.Column);
   Console.WriteLine("Row " + myHitTest.Row);
   Console.WriteLine("Type " + myHitTest.Type);
   Console.WriteLine("ToString " + myHitTest.ToString());
   Console.WriteLine("Hit " + myHitTest.Type.ToString());
}

Private Sub DataGrid1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)
    Console.WriteLine()
    Dim myHitTest As DataGrid.HitTestInfo
    ' Use the DataGrid control's HitTest method with the x and y properties.
    myHitTest = DataGrid1.HitTest(e.X, e.Y)
    Console.WriteLine("Column " & myHitTest.Column)
    Console.WriteLine("Row " & myHitTest.Row)
    Console.WriteLine("Type " & myHitTest.Type)
    Console.WriteLine("ToString " & myHitTest.ToString)
    Console.WriteLine("Format " & myHitTest.Type.ToString)
End Sub

Commenti

La DataGrid.HitTestInfo classe, in combinazione con il HitTest metodo del DataGrid controllo, viene utilizzata per determinare quale parte di un DataGrid controllo ha fatto clic sull'utente. La DataGrid.HitTestInfo classe contiene la riga, la colonna e parte della griglia su cui è stato fatto clic. Per un elenco completo delle parti della Type griglia, vedere l'enumerazione DataGrid.HitTestType restituita dalla proprietà .

Per restituire un DataGrid.HitTestInfooggetto , richiamare il HitTest metodo dall'evento MouseDown del DataGrid controllo . Passare le x proprietà e y dell'oggetto MouseEventArgs al HitTest metodo .
