Hi Logvenchev,
Note that you need to add the ScriptManager control on your page in order to enable AJAX, which is required for using the RadControls for ASP.NET AJAX. You are able to select only the default skin, because since
Q3 2011 the RadControls' skins (except
Default) are moved to a separate assembly. You can find more information on the matter in this
forum thread.
The trial message that appears is related to the other RadControls, as their trial version is included with the free edition of RadFormDecorator. If you use only the RadFormDecorator on your page, this message will not be displayed.
All the best,
Slav
