Sets a flag indicating that custom personalization data for the WebPartManager control has changed.
Assembly: System.Web (in System.Web.dll)
The method sets a flag that ultimately causes the personalization components in the Web Parts control set to save the updated personalization data. For more information on the scenarios that can cause changes to the personalization data tracked by the WebPartManager control, see the IPersonalizable.IsDirty property.
The method cannot be called directly from your code, and cannot be overridden, because it is used internally by the Web Parts control set as part of the Web Parts personalization feature.Notes to Inheritors
The method can be called by a derived WebPartManager class. This would be useful if you want to customize the personalization components of the Web Parts control set, and thus need to control the process of setting flags for personalization data.
