Control.OnLostFocus Method

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

Called before the LostFocus event occurs.

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

Syntax

'Declaration
Protected Overridable Sub OnLostFocus ( _
    e As RoutedEventArgs _
)

protected virtual void OnLostFocus(
    RoutedEventArgs e
)

Parameters

e
Type: System.Windows.RoutedEventArgs
The data for the event.

Remarks

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