TreeViewItem.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.Controls (in System.Windows.Controls.dll)

Syntax

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

protected override void OnGotFocus(
    RoutedEventArgs e
)

Parameters

e
Type: System.Windows.RoutedEventArgs
A RoutedEventArgs that contains the event data.

Remarks

This implementation sets the selected item of the parent TreeView to the TreeViewItem that is in focus.

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