Occurs when a mouse button is clicked two or more times.
Assembly: PresentationFramework (in PresentationFramework.dll)
Although this routed event seems to follow a bubbling route through an element tree, it actually is a direct routed event that is raised along the element tree by each UIElement. If you set the Handled property to true in a event handler, subsequent events along the route will occur with Handled set to false. This is a higher-level event for control consumers who want to be notified when the user double-clicks the control and to handle the event in an application.
Control authors who want to handle mouse double clicks should use the MouseLeftButtonDown event when ClickCount is equal to two. This will cause the state of Handled to propagate appropriately in the case where another element in the element tree handles the event.
The Control class defines the PreviewMouseDoubleClick and events, but not corresponding single-click events. To see if the user has clicked the control once, handle the MouseDown event (or one of its counterparts) and check whether the ClickCount property value is 1.
The following example shows how to attach an event handler to theevent.
<Button Name="btn" Background="Red" MouseDoubleClick="ChangeBackground"> Background </Button>
The following example shows the event handler of theevent.
