ButtonBase.OnMouseMove(MouseEventArgs) Method


Provides class handling for the MouseMove routed event that occurs when the mouse pointer moves while over this element.

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



The event data.


This implementation marks the MouseMove event as handled by setting the Handled property of the event data to true when ClickMode is not set to Hover and IsPressed is true. To respond to the MouseMove event, attach an event handler to the PreviewMouseMove event, or call AddHandler(RoutedEvent, Delegate, Boolean) with handledEventsToo set to true.

Notes to Inheritors

If you override OnMouseMove(MouseEventArgs), always call the base implementation in your OnMouseMove(MouseEventArgs) 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.
