As I step through the code, it seems that the problem comes when I am trying to update the cell value.

The code
dr[e.Cell.Column.Key] = e.Cell.Value;
shows that the e.Cell.Value is captured, but the e.Cell.Column is undefined value.

If I replace it as
dr["RegionDescription"] = e.Cell.Value;
then it updates just fine.

What do I need to do to the set up of the MMultrawebgrid to map the e.Cell.Column.Key value?

Because you did not mention it in the third party instructions, I am interpreting that I don't set any of the column properties in the Quick Design. Is that true?


Thanks
