Hi George ,
Thanks for contacting us and for your question.
Indeed, the new implementation of RadForm
is no longer part of Telerik.WinControls
namespace. It has been moved to Telerik.WinControls.UI
You will be able to find information on how to utilize the new RadForm as soon as we update our help to reflect the recent changes.
I hope this is helpful. Do not hesitate to write back if you have further questions.
the Telerik team
