Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)
Syntax
'Declaration
Protected Overrides Sub OnMouseLeftButtonUp ( _
e As MouseButtonEventArgs _
)

MouseButtonEventArgs e
)
Parameters
- e

The data for the event. The event data reports that the left mouse button was released.
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.
