I can save the persistence layout of any number of documents and panels with the following code:
_DockingFWState = New NDockingFrameworkState(DockMgr)
_DockingFWState.PersistDocuments = True
_DockingFWState.Save(XMLFileName)

However, when I try to load the persistence layout with the following code, only two panels are ever loaded onto the form:
_DockingFWState = New NDockingFrameworkState(DockMgr)
_DockingFWState.Load(XMLFileName)

What do I need to change to ensure that all panels are loaded when I load the XML file for persistent layout of Nevron panels and documents?

Hello Luis,

Make sure you set unique Key and Text properties to each one.
Let us know if the problem persist.

Now it works properly

Thanks
