I am actually developing the feature at the moment. I will expose a new attribute that will have editor control, target property and style (dropDown, Modal, None) as properties and will enable the user to define an editor quite more easily than the WinForms approach with inheriting from UITypeEditor. Thus you will be able to add directly just a RadNumericUpDown for a particular numeric property.
Will that fit into your scenario ? If appropriate for you, could you share more information about your exact settings so that we can test it during the QA process ?
Thank you in advance for the cooperation or any feedback that you have.
