Hello Jerami,
You can use ContentBlock control which wraps RadEditor control. If you want to use a user control you cannot use the RadEditor in the context of a ControlDesigner. In this case you will need a custom control with a custom control designer. The control should inherit from SimpleView( if you do no intend to reuse one of the built-in controls as a basis). The control designer should inherit from ControlDesignerBase.
All the best,
