BarManager.BeforeLoadLayout Event

Occurs before a layout is restored from storage (a stream, xml file or the system registry).

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

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type LayoutAllowEventArgs containing data related to this event.

The following LayoutAllowEventArgs properties provide information specific to this event.
Property Description
Allow Gets or sets whether to allow upgrading the control layout.

Expanded Remarks

The BeforeLoadLayout event allows you to prevent the layout from being restored from storage and thus being applied to the current BarManager.

This event is fired when an attempt is made to restore a layout from storage using one of the following methods: RestoreFromRegistry, RestoreFromStream and RestoreFromXml. To stop the layout from being restored from the storage set the event's Allow parameter to false.

The event's PreviousVersion parameter defines the version of the layout being restored. This can be compared with the version of the current layout specified by the DevExpress.Utils.OptionsLayoutBase.LayoutVersion property. The restoring of the layout can be cancelled, for instance if the versions do not match.
