Hi,
It's a long time since I reviewed that control, so I can't say unless I do some research what it does support and what it doesn't. The code should be attached to the KB article on the subject and the attachment is stored within the KB, so it should be downloadable. Please let me know if you have any problems with downloading it. The article can be found here.
Please keep in mind that this custom control was written for version 6.3 of the framework, and to my knowledge, it has not been updated to be directly usable in 6.4. Some changes will be required in order to make that happen, because of the changed resources mechanism introduced in 6.4 by the Themes and Custom Controls.
