For anyone else who uses DevExpress AspGrid control, this may help you get past an issue if you are dynamically generating the columns and there is a possibility your number of columns will change with each postback.

I wasted about 30 minutes today trying to figure out why I was receiving errors the second time I ran a report (with different criteria).  One of my co-workers found this link:

Two things I took away from this:

1)      I didn’t know DevExpress had a facebook page that actually had useful information on it.

2)      I love DevExpress products, but I sometimes don’t like the little quirks that come along with them.
