NavigationPaneFlyoutClosed Event

Occurs after the navigation pane flyout has been closed.

Syntax

Visual Basic

'Declaration
 
Public Event NavigationPaneFlyoutClosed As NavigationPaneFlyoutClosedEventHandler

C#

public event NavigationPaneFlyoutClosedEventHandler NavigationPaneFlyoutClosed

Event Data

The event handler receives an argument of type NavigationPaneFlyoutClosedEventArgs containing data related to this event. The following NavigationPaneFlyoutClosedEventArgs properties provide information specific to this event.

Property	Description
Canceled	Returns whether the flyout session was canceled, for example, whether the end user pressed the Escape key to close the flyout.
SelectedItem	Returns the UltraExplorerBarItem that was selected by the end user during the flyout session, or null if the flyout session was canceled.

Remarks

The end developer can programmatically close the navigation pane flyout by calling the CloseNavigationPaneFlyout method; whether the flyout is closed in this manner or via user interaction, the NavigationPaneFlyoutClosed event is fired. Note that because it is not possible to prevent the navigation pane flyout from being closed, no cancelable event fires prior to its closing.

Example

The following code sample demonstrates how to use the NavigationPaneFlyoutClosed event to receive a notification when the navigation pane flyout is closed:
