Creating a RadSkinManager Widget for Forms

Hi,

I have a project where I'm trying to skin forms using the RadSkinManager.

What I'd like to do is create a custom widget with designer in Sitefinity that has a RadSkinManager for some custom form builder field that have Telerik controls (RadComboBox, RadInput, etc.) as well as a RadFormDecorator for basic form elements (Input, Select, etc.).

I have a fair bit of experience creating custom widgets but for some reason I can't get this one to work. It renders properly and I can set properties with the designer and everything but it does not change the skin of the controls on the page.

If I create a basic usercontrol with the same functionality it works but I need this widget to be compiled into it's own DLL which is why the usercontrol isn't a viable solution.

Any ideas as to why the RadSkinManager does not work in a Sitefinity widget?

Thanks,
Steve
