I use the RadDock.LoadFromXml(file), it works fine for all visible tool and document windows for the exception of hidden tab document windows.

When I hide all tab document windows, save to xml then restart my app and load from xml, they remain hidden but if at least one tab document window is not hidden, none of them remain hidden, they are all docked tab document again.

Looking at the xml file, it shows the DesiredDockState="Hidden" correctly on all tab documents that should remain hidden.

Hello Luc,

Thank for writing.

I tested described issue with version 2013.1.220 but I was not able to reproduce the described behavior at my side. You can find attached the sample demo project that I used during my tests. Could you please take a look at it and modify it in a way to replicate the undesired behavior? This will allow me to investigate it and provide you with further support.

Thank you in advance for your cooperation. I am looking forward to your reply.

Kind regards,
Anton
