RichTextBox.OnMouseLeave Method

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

Called before the MouseLeave event occurs.

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

Syntax

'Declaration
Protected Overrides Sub OnMouseLeave ( _
    e As MouseEventArgs _
)

protected override void OnMouseLeave(
    MouseEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseEventArgs
The data for the event.

Remarks

The OnMouseLeave method is called before any event handler for the MouseLeave event is called. This method allows derived classes to handle the MouseLeave event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

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

Notes to Inheritors

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