I have got all the properties and tagprefix working but not the designer.

I got the thing compiling and even running complete with designer  code .... but it won't give me the designer object at design  time. "Error Creating Control".

I decided to lump that because my control  was too complicated and simply made a bog standard  one as in
ms-help://MS.VSCC/MS.MSDNVS/cpguide/html/cpconhtmldesignersample.htm

And used their SimpleDesigner aswell.

Same thing - it compiles and runs with no errors and I can get it into the toolbox. But every time "Error Creating Control" when dragged from the toolbox.

Has anyone done this ?

I am a bit confused as the help says this ::
A Web Forms designer class controls the design-time appearance of a control by providing design-time HTML to a designer host. The .NET Framework provides a base designer class, System.Web.UI.ControlDesigner, that provides base functionality for a server control designer. ControlDesigner defines the following key methods for rendering design-time HTML.

which clearly states "System.Web.UI.ControlDesigner" but really means "System.Web.UI.Design.ControlDesigner"

So what sthe form on all this then guys ... does it work  or doesn't it ... is it me or isn't it ?
