    I cannot seem to add a RadFilter control to my aspx page or user control.

    It keeps showing "RadFilter is not a known element".

    The telerik assembly was registered at the top of the page and also in the web.config but still I can't get it to work.

    Am I missing something here or what?

    Thanks for you help.
