LayoutAllowEventArgs Class

Provides data for events raised when upgrading a control’s layout, allowing you to cancel the upgrade (e.g. BaseView.BeforeLoadLayout, BarManager.BeforeLoadLayout, etc.).

Namespace: DevExpress.Utils

Assembly: DevExpress.Data.v22.1.dll


public class LayoutAllowEventArgs :


The BeforeLoadLayout event occurs before a layout is restored from storage (a stream, XML file or the system registry), allowing you to prevent the layout from being applied. To cancel the layout application, set the LayoutAllowEventArgs.Allow property to false.

To obtain the textual representation of the previous layout version, use the LayoutUpgradeEventArgs.PreviousVersion property.


LayoutAllowEventArgs objects are automatically created, initialized and passed to the BeforeLoadLayout event handlers.
