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.
