ContentElement.MouseEnter Event


Occurs when the mouse pointer enters the bounds of this element.

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

public event MouseEventHandler MouseEnter

MouseEnter is a Routed Events Overview that uses the  routing strategy. Direct routed events are not raised along a route; instead, they are handled in the same element where they are raised. However, they do enable other aspects of routed event behavior, such as event triggers in styles.GTMT

Although MouseEnter tracks when the mouse pointer enters the bounds of an element, this event more literally reports that the IsMouseOver property value has changed from false to true on this element.

This event creates an alias for the Mouse.MouseEnter  for this class, so that MouseEnter is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the MouseEnter event are attached to the underlying Mouse.MouseEnter attached event and receive the same event data instance. GTMT
