    Hi there,

    I made a user control and designed it using Telerik.Framework.Web.Design.ControlDesigner Class as showen in http://www.sitefinity.com/help/developer-manual/control-adding-controls-designers.html.

    Now issue is that I am using the control in most of the website and it is working flawless. But one of my current one it is giving me the following error.


    Default control designer not implemented!

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Hello Nimit,

    In your class FormBuilderDesigner you explicitly throw not implemented exception.

    Kind regards,
