Can't Get FlexGrid To merge

What does it take to get the FlexGrid to merge.
I've tried setting the merge property everyway I can, it it will not merge.
I've tried doing it in code, and it does not work.

I have one column that is nothing but a person't name from a database, and I want to merge it, but it won't work.
Is there something I'm missing??

If the grid is still bound to the datacontrol then I doubt that it will allow fields to merge

Not sure if this is the case, but worth checking
