TreeViewItem.OnMouseLeftButtonUp Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Provides handling for the MouseLeftButtonUp event.

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

Syntax

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

protected override void OnMouseLeftButtonUp(
    MouseButtonEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseButtonEventArgs
A MouseButtonEventArgs that contains the event data.

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 does not change the handled state (the Handled property) of the MouseButtonEventArgs event data.

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.
