In order the community to benefit, I will post a suggestion here as well. Hosting a form can be achieved by using RadMenuHostItem to host the form:
RadDropDownButton button =
Form form =
form.Dock = DockStyle.Fill;
RadMenuHostItem host =
Please let us know if there is something else I can help you with.
