Currently, we are working on creating help topics regarding this control. They will be available very soon.
As for the usage of the RadScrollablePanel, its functionality is pretty much the same as of a standard panel except the fact that this control introduces the possibility to use styled scrollbars to keep the visual consistency of your application (since the standard RadPanel control does not support this feature).
I hope this helps.
Sincerely yours,
Deyan
