Thank you for writing.
You cannot find a smart tag in the RadForm because it is a not a control (the same holds true for the standard Windows.Form).
Nevertheless, RadForm is listed in the VisualStyleBuilder and you could edit or create new themes using it (you can find the VisualStyleBuilder application in your start menu under the Telerik folder). Once your custom theme is created as an XML file you could add it in design/run time to your RadForm. For more information of using the VSB visit this video:
