Occurs after a layout whose version doesn’t match the current layout version has been loaded from a stream, xml file or system registry.
The LayoutUpgrade event's data class is LayoutUpgradeEventArgs. The following properties provide information specific to this event:
|NewHiddenItems||Returns an array of items that exist in the current control but do not exist in the layout being loaded. These items are hidden. This property is in effect for the LayoutControl.|
|PreviousVersion||Returns the textual representation of the previous layout version.|
The LayoutUpgrade event allows the current layout to be customized after an earlier version of the layout has been loaded and applied to the control. See the NavBarControl.LayoutVersion topic for more information.
