Exemplos

O exemplo seguinte usa o HitTest método num MouseDown evento para devolver o DataGrid.HitTestInfo objeto. A linha, coluna e parte da grelha são então impressas.

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

Observações

A DataGrid.HitTestInfo classe, em conjunto com o HitTest método do DataGrid controlo, é usada para determinar em que parte DataGrid do controlo o utilizador clicou. A DataGrid.HitTestInfo classe contém a linha, coluna e parte da grelha que foi clicada. Consulte a DataGrid.HitTestType enumeração devolvida pela Type propriedade para uma lista completa das partes da grelha.

Para devolver um DataGrid.HitTestInfo, invoca o HitTest método a partir do MouseDown evento de DataGrid controlo. Passe as x propriedades e y do MouseEventArgs para o HitTest método.
