Slider.OnMouseEnter Method
[ 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.
Assembly: System.Windows (in System.Windows.dll)
Parameters
- e
- Type: System.Windows.Input.MouseEventArgs
A MouseEventArgs that contains the event data.
The OnMouseEnter method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Because Windows Phone only provides a touchscreen surface for pointer interactions, the OnMouseEnter(MouseEventArgs) event will not fire unless your control is tapped onscreen. Therefore OnMouseEnter(MouseEventArgs) and OnMouseLeftButtonDown(MouseButtonEventArgs) are functionally redundant.
Notes to InheritorsWhen overriding OnMouseEnter in a derived class, make sure to call the base class’s OnMouseEnter method so that registered delegates receive the event.
