Custom event for wpf UIElement

Question

Is is possible to fire event when a UIElement's location is changed in wpf? We can fire location changed event in case of Windows but can we have a custom event which fires when a UIElement's location is changed in the Window.

Maybe this link will help you, UIElement supports a lot of Events. I think what you are looking for are Manipulation Events or the LayoutUpdate Event.

It's not possible for the general case. The UIElement doesn't even know the location it's rendered to.

You can do it for particular cases, though. You can use events of the layout parent, like the Left and Top attached property of the Canvas, the scroll offset of a ScrollViewer, etc., depending on where your UIElement is in the visual tree.
