Occurs before a layout is restored from a storage, allowing you to cancel this action.
public event LayoutAllowEventHandler BeforeLoadLayout
Public Event BeforeLoadLayout As LayoutAllowEventHandler
The BeforeLoadLayout event handler receives an argument of the LayoutAllowEventArgs type.
The following properties provide information specific to this event.
The BeforeLoadLayout event allows you to prevent the layout from being restored from a storage (a stream or a string) and being applied to the current control.
This event is fired when an attempt is made to restore a layout using the ASPxPivotGrid.LoadLayoutFromStream or ASPxPivotGrid.LoadLayoutFromString method. To stop the layout from being restored, set the event parameter's LayoutAllowEventArgs.Allow property to false.
The event parameter's LayoutUpgradeEventArgs.PreviousVersion property defines the version of the layout being restored. This can be compared with the version of the current layout specified by the OptionsLayoutBase.LayoutVersion property of the ASPxPivotGrid.OptionsLayout object. The layout restoration can be canceled, for example, if the versions do not match.
