[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Called before MouseLeftButtonUp event occurs.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)

protected override void OnMouseLeftButtonUp(
	MouseButtonEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseButtonEventArgs
The data for the event.

The OnMouseLeftButtonUp method is called before any event handler for the MouseLeftButtonUp event is called. This method allows derived classes to handle the MouseLeftButtonUp event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

This implementation marks the MouseLeftButtonUp event as handled by setting the Handled property of the event data to true.

Notes to Inheritors

When overriding OnMouseLeftButtonUp method in a derived class, be sure to call the base class’s OnMouseLeftButtonUp method so that registered delegates receive the event.
