We’ve been using yours controls since two years. I’m very satisfied. Now I’ve try to use RadFormDecorator, but I’ve a problem in FF 3.0.3, in IE everything works ok.
I create dynamically CheckBoxList (3 items), I use my own skin, and this works fine in both browsers.
<telerik:RadFormDecorator EnableEmbeddedSkins="false" ID="RadFormDecorator1" Skin="myCustom" DecoratedControls="RadioButtons,CheckBoxes" Runat="server"></telerik:RadFormDecorator>
