AutoCompleteBox.OnSelectionChanged Method

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

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

Syntax

'Declaration
Protected Overridable Sub OnSelectionChanged ( _
    e As SelectionChangedEventArgs _
)

protected virtual void OnSelectionChanged(
    SelectionChangedEventArgs e
)

Parameters

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

Remarks

The SelectionChanged event occurs when the selected item changes.

Raising an event invokes the event handler through a delegate. The OnSelectionChanged 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 OnSelectionChanged in a derived class, be sure to call the base class’s OnSelectionChanged method so that registered delegates receive the event.
