NavigationFrame.ControlReleasing Event

Fires when a dynamically populated NavigationPage is deselected.

Namespace:DevExpress.XtraBars.Navigation
Assembly:DevExpress.XtraBars.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.XtraBars.Navigation.ControlReleasingEventArgs containing data related to this event.

Expanded Remarks

The ControlReleasing event fires only for pages that were dynamically populated on the QueryControl event. If the event's e.KeepControl property is set to true, the page will keep its content and will not re-fire the QueryControl the next time it is activated.

Otherwise, if the e.KeepControl equals false, the page loses its content and needs to be re-populated the next time it is displayed. After the content was taken from a page (e.KeepControl = false), you can keep its instance in memory or completely destroy it. Use the event's e.DisposeControl property to choose the required action.
