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 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 sets IsDropDownOpen for the parent ComboBox to false and marks the MouseLeftButtonUp event as handled by setting the Handled property of the event data to true.

Notes to Inheritors

If you override OnMouseLeftButtonUp, you can prevent registered delegates from receiving events by setting Handled to true. For more information about routed events and the Handled property, see Events Overview for Silverlight.
