Remarks

Typically, controls are composited such that the various elements inside the control (the visual tree) will all report the mouse state for the containing control. For example, a ListBox style control will report IsMouseOver as true if the mouse is anywhere over its geometry, including any ListBoxItem.

Although an analogous "IsMouseOverChanged" event does not exist, several similar events do. For example, you can handle MouseEnter, MouseMove, and IsMouseDirectlyOverChanged.

If this element captures the mouse, this property remains true until mouse capture is lost and the mouse pointer leaves the element bounds.

Some controls deliberately capture the mouse on certain actions that do not appear to directly involve the mouse. This can lead to IsMouseOver being true even though the mouse has not apparently moved.

IsMouseOver is introduced in the .NET Framework version 3.5. For more information, see Versions and Dependencies.
