Not really. The code is in a single method, so I can see it all happening. In the debugger I check all the values - it's all fine, but it fails on DataBind().

I ended up not databinding but rather just Adding the items manually and that worked fine.

I hate stuff like this and it seems to be happening with some regularity. These bugs that rae buried deep in the ASP.Net runtime somewhere with no clue what's failing. Costs soooooo much wasted time...
