Slider.OnMouseEnter Method

Provides class handling for the MouseEnter event.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)

protected override void OnMouseEnter(
	MouseEventArgs e
)

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 Inheritors

When overriding OnMouseEnter in a derived class, make sure to call the base class’s OnMouseEnter method so that registered delegates receive the event.
