ButtonBase.OnMouseLeftButtonUp Method

Provides class handling for the MouseLeftButtonUp routed event that occurs when the left mouse button is released while the mouse pointer is over this control.

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

protected override void OnMouseLeftButtonUp(
	MouseButtonEventArgs e
)

Parameters

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

This implementation marks the MouseLeftButtonUp event as handled by setting the Handled property of the event data to true when ClickMode is not set to Hover. To respond to the MouseLeftButtonUp event, attach an event handler to the PreviewMouseLeftButtonUp event, or call AddHandler(RoutedEvent, Delegate, Boolean) with handledEventsToo set to true.

When ClickMode is set to Release is IsPressed is true, this method raises the Click event.

Notes to Inheritors

If you override OnMouseLeftButtonUp, always call the base implementation in your OnMouseLeftButtonUp implementation. Failure to call the base implementation prevents base classes from handling the event with a class handler, which might change the run-time behavior of the final class. You can call the base implementation either before or after your special handling, depending on your requirements.
