I am glad that you have found the solution. Actually, you can get this to work with ContentView control as well, just make sure that the TagItemKey of the ContentView control and TagsList control are the same (e.g. "BussinessTagID"). This key is basically specifying the query string key in which the Tag id will be stored. In order for the two controls to work together, they both need to operate on the same query string (in your case below it was CntTagID).
I hope you'll find this information helpful. Let us know if there is anything else we can do for you.
