protected:
 override void OnMouseLeftButtonDown(System::Windows::Input::MouseButtonEventArgs ^ e);
protected override void OnMouseLeftButtonDown (System.Windows.Input.MouseButtonEventArgs e);
override this.OnMouseLeftButtonDown : System.Windows.Input.MouseButtonEventArgs -> unit
Protected Overrides Sub OnMouseLeftButtonDown (e As MouseButtonEventArgs)

MouseButtonEventArgs

Remarks

This implementation handles the MouseLeftButtonUp event so that the GridViewHeaderRowPresenter.OnMouseLeftButtonUp can support the drag-and-drop operation that moves a column. This method captures the mouse and sets the Handled event argument to true.
