I've been part of thread that appears to have slipped of the radar here. Here's the thread:
http://www.syncfusion.com/support/Forums/message.aspx?&MessageID=56622Perhaps the person that was helping me is out, but I'm wondering if someone else could take a look at this problem. I'm nearing the end of my 30-day eval and have been working on this same issue for some time. I'm concerned that my eval period will expire and I still won't have a solution to this issue.
FYI...the basic problem here (as demonstrated by the example attached at the end of the thread) is that the custom cell is requiring IConvertible when it shouldn't. This error only shows up when you edit and leave a new entry for the custom cell.
