ButtonBase.OnMouseEnter(MouseEventArgs) Method


Provides class handling for the ClickMode routed event that occurs when the mouse enters this control.

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



The event data for the MouseEnter event.


When ClickMode is set to Hover, this implementation marks the MouseEnter event as handled by setting the Handled property of the event data to true and raises the Click event.

Notes to Inheritors

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