I am new to RadControls but so far they work fine.  I am not finding a reference that explains the prefered method for creating DocumentWindows for the RadDock Control using the Visual Studio form designer.  My program could have any number of forms and are based on different "types" that I define.  Before using RadDock, I would use the Visual Studio designer to create the basics for each type of form, then at run time dynamically add to and-or modify the base form for each instance required.  Because I don't know in advance what types of forms will be displayed, I don't think adding form types to the RadDock control itself at design time is a useful approach.  I found that if I use  AutoDetectMdiChildren, if a DocumentWindow form is "hidden" when the user closes it and I re-show the form later, it is blank.  To correct this I found the following works just fine. 
First don't user AuoDetectMdiChildren.
Second in the "formname.Designer.vb" file make the following change....

'Inherits System.Windows.Forms.Form

Inherits Telerik.WinControls.UI.Docking.DocumentWindow

If I later want to modify the form with the Visual Studio form designer, I un-comment the first line and comment the second.

This is working without a hitch, but since I don't find any reference that describes the "proper method", I just wanted to ask if this sounds OK or if there is a better "recommended" pratice that I should be following.  To summarize, I want to be able to visual modify DocumentWindow forms for the purpose of creating defined "types" of forms that my program can select from at runtime and the user needs the ability to hide and re-display these forms.

Thanks
