Provides class handling for the MouseLeftButtonDown routed event that occurs when the left mouse button is pressed while the mouse pointer is over this control.
Assembly: PresentationFramework (in PresentationFramework.dll)
protected override void OnMouseLeftButtonDown( MouseButtonEventArgs e )
protected: virtual void OnMouseLeftButtonDown( MouseButtonEventArgs^ e ) override
override OnMouseLeftButtonDown : e:MouseButtonEventArgs -> unit
Protected Overrides Sub OnMouseLeftButtonDown ( e As MouseButtonEventArgs )
The event data.
This implementation marks the MouseLeftButtonDown event as handled by setting the property of the event data to true when is not set to Hover. To respond to the MouseLeftButtonDown event, attach an event handler to the PreviewMouseLeftButtonDown event, or call AddHandler with handledEventsToo set to true.
Notes to Inheritors:
If you override, always call the base implementation in your implementation. Failure to call the base implementation prevents base classes from handling the event with a class handler, which might change the run-time behavior of the final class. You can call the base implementation either before or after your special handling, depending on your requirements.
