Event Data

The PopupClosing event's data class is ClosePopupEventArgs. The following properties provide information specific to this event:

Property	Description
CloseMode	Gets a value indicating how the popup editor’s dropdown window has been closed.
EditValue	Gets or sets the editor’s value.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Source	Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

The event parameter provides the CloseMode and EditValue properties, allowing you to obtain how the dropdown is being closed and the editor’s value, respectively. After the dropdown has been closed, the editor fires the PopupBaseEdit.PopupClosed event.
