RichTextBox.OnMouseLeftButtonUp Method

Called before the 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.

The RichTextBox implementation marks the MouseLeftButtonUp event as handled by setting the Handled property of the event data to true.

Notes to Inheritors

When overriding the OnMouseLeftButtonUp method in a derived class, be sure to call the base class’s OnMouseLeftButtonUp method so that registered delegates receive the event.
