AutoCompleteBox.OnDropDownClosed Method

Silverlight

Raises the DropDownClosed event.

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

'Declaration
Protected Overridable Sub OnDropDownClosed ( _
	e As RoutedPropertyChangedEventArgs(Of Boolean) _
)

The DropDownClosed occurs when the IsDropDownOpen property has changed from true to false.

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

Silverlight

Supported in: 5, 4, 3
