Hello Prabakaran,

Note that RadDocking has a built-in mechanism for saving its layout which you can use instead of PersistenceFramework. However, keep in mind that this mechanism (neither the persistence framework) cannot save automatically the content of the panes. It only remembers the current UI state (the set properties) of the panes, groups and split containers. In order to save the content of the panes you can handle the ElementLoaded event of RadDocking and set the content of the newly created pane manually. You can see how to do that in the Save/Load the Content of the Panes help article.
