Kendo DropDownList validation in grid

I am reviewing the question I raised on the Kendo forums (which are now read-only). Here is the original stream .

The solution proposed by John offers:

If you pull a validation message out of range, it will appear (use jQuery to add it to the parent).

I have a health check - I just can’t get a verification message (at least where it can be seen). I'm not sure where to add.

Any advice is greatly appreciated.
