Custom control error: 'Type "xxx" cannot be re - Sitefinity - Bugs & Issues

I wanted to be able to limit the categories that the Category widget displays (by default all of them) and I found this -

http://www.sitefinity.com/developer-network/forums/designing-styling/using-categories-control-to-limit-shown-categories

, which sounded good. So I took this code and followed the instructions from here -

http://www.sitefinity.com/documentation/documentationarticles/developers-guide/how-to/how-to-create-a-coverflow-control/creating-an-empty-silverlight-based-control/creating-a-custom-control

(I changed the name of the namespace to SubCategoryWidget and the name of the code file to SubCategory), and then here -

http://www.sitefinity.com/documentation/documentationarticles/developers-guide/how-to/how-to-create-a-coverflow-control/registering-and-using-the-control

However, when I drag the newly created control onto a page I get the error 'Type "SubCategoryWidget.SubCategory" cannot be resolved''. The cause seems fairly obvious in that the control cannot be found, so I tried changing the ControlType to ~/SubCategoryWidget.SubCategory; /SubCategoryWidget.SubCategory and other variations without success.

I still think it's probably a simple thing that's causing the problem, but I can't see what it is. Can anyone help?

BTW, Our site is using VB.NET, so I have converted the C# code.

Cheers.

Got there in the end. When registering the control, in the Control CLR Type or Virtual Path field the format needed to be ProjectName.NameSpace.CodeFileName

Can you give a concrete example?

I have web-project named SitefinityWebApp. I added CustomWidgets/LibrarySelector and then added file MyLibrarySelector.ascx. The .cs shows namespace to be SitefinityWebApp.LibrarySelector.

I tried following combinations:

~/Sitefinity/CustomWidgets/LibrarySelector/SitefinityWebApp.SitefinityWebApp.LibrarySelector.MyLibrarySelector.ascx

~/CustomWidgets/LibrarySelector/SitefinityWebApp.SitefinityWebApp.LibrarySelector.MyLibrarySelector.ascx

~/SitefinityWebApp.SitefinityWebApp.LibrarySelector.MyLibrarySelector.ascx

~/SitefinityWebApp.LibrarySelector.MyLibrarySelector.ascx

SitefinityWebApp.SitefinityWebApp.LibrarySelector.MyLibrarySelector.ascx

SitefinityWebApp.LibrarySelector.MyLibrarySelector.ascx

And all of the above without namespace before I got to this thread.

Thanks.

Hi Shriyal,

I've only just seen your question so this is probably way too late.

I just created a class, not a user control, so as you're using an ascx file you just need to add in the path to that file e.g. ~/CustomWidgets/LibrarySelector/MyLibrarySelector.ascx.
