Occurs when the mouse pointer moves while over this element.

This event creates an alias for the Mouse.MouseMove attached event for this class, so that is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying Mouse.MouseMove attached event and receive the same event data instance.
This example shows how to change the dimensions of an object when the mouse pointer moves on the screen.
The example includes an Extensible Application Markup Language (XAML) file that creates the user interface (UI) and a code-behind file that creates the event handler.
<Window x:Class="WCSamples.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="mouseMoveWithPointer" Height="400" Width="500" > <Canvas MouseMove="MouseMoveHandler" Background="LemonChiffon"> <Ellipse Name="ellipse" Fill="LightBlue" Width="100" Height="100"/> </Canvas> </Window>
The following code behind creates the event handler. When the mouse pointer moves, the height and the width of the Ellipse are increased and decreased.
