ListBoxItem.OnGotFocus Method

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

Provides handling for the GotFocus event.

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

Syntax

'Declaration
Protected Overrides Sub OnGotFocus ( _
    e As RoutedEventArgs _
)

protected override void OnGotFocus(
    RoutedEventArgs e
)

Parameters

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

Remarks

This implementation updates the appearance of the ListBoxItem when it receives focus.

The OnGotFocus method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

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