PreviewMouseMove Attached Event

Mouse.PreviewMouseMove Attached Event


Occurs when the mouse moves over an element.

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

See AddPreviewMouseMoveHandler, RemovePreviewMouseMoveHandler

This event occurs both when the mouse pointer is newly moved in the element bounds, and also when the mouse pointer moves while still remaining in the element bounds.

This is an attached event. WPF implements attached events as routed events. Attached events are fundamentally a XAML language concept for referencing events that can be handled on objects that do not define that event, which WPF expands upon by also enabling the event to traverse a route. Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, you use a designated Add*Handler method. For details, see Attached Events Overview.
