I found that the default RadDocking.SaveLayout and LoadLayout functionality was not sufficient for my needs so I created a bunch of custom serializable classes that I populate from the RadDocking control. Initially this worked out for me but then I tested a scenario with a floating pane and could not get access to it. The RadDocking.Items collection only returns docked RadSplitContainers and the RadDocking.ToolWindows collection is a private field so I cannot access it from my code. Is there any way to access the ToolWindows in a RadDocking control so I can serialize them myself? If not would it be possible to get a public readonly property that returns an IEnumerable(Of ToolWindow) from the ToolWindows field? Alternatively, the RadDocking.Items collection would ideally contain the DocumentHost, docked SplitContainers and floating ToolWindows but I doubt that would be easily changed.
