AutoCompleteBox.OnDropDownClosing Method

Silverlight

Raises the DropDownClosing event.

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

protected virtual void OnDropDownClosing(
	RoutedPropertyChangingEventArgs<bool> e
)

The OnDropDownClosing occurs when the IsDropDownOpen is changing from true to false.

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

Silverlight
