TextBox.OnMouseLeave Method

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

Called before 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

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.

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

Notes to Inheritors

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