I'm trying to move my ASP.NET AJAX to Kendo MVC, but there is one way to customize the radioButton that doesn't translate to Kendo.  A picture/video would be more descriptive, but I'll just sent the html as that's my only option.  It toggles the multiple choices for the radio button, very intuitive for the user...  It would be nice to be able to do this on the Kendo side as well.

                            <telerik:RadButton ID="rbFld1" runat="server" ToggleType="CustomToggle" ButtonType="StandardButton" AutoPostBack="false" Checked="false" OnClientToggleStateChanged="toggleStateChanged" DataField="Fld1" >
