[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Provides class handling for the MouseEnter event that occurs when the user’s touch enters this control.

Namespace:  System.Windows.Controls.Primitives

protected override void OnMouseEnter(
	MouseEventArgs e
)

When ClickMode is set to Hover, this method raises the Click event.

Notes to Inheritors

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