Called before MouseLeftButtonUp event occurs.

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

Syntax

'Declaration
Protected Overrides Sub OnMouseLeftButtonUp ( _
    e As MouseButtonEventArgs _
)
protected override void OnMouseLeftButtonUp(
    MouseButtonEventArgs e
)

Parameters

Remarks

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.
