Prevent rowstate change for one column

[Carl]

Hi!

I have an DataTable with one extra column that I've added manually, and is
not in the database. I use this col for various calculations, and it should
never be saved to the db. That works fine, except for one thing: when I
change the value in a row for that col, the RowState becomes Modified.
That's natural I guess, but it's unneccecary because it sends unmodified
rows to the db. Is there a way of marking a col as "computed" or other
technique to avoid changing the rowstate when changing that columns value?

regards

Carl

datarow.AcceptChanges()

 

[Carl]

That is not an option in my case, since there might (will) be other changes
to the row, and I do not wish to accept those changes.

Then do a test to see If Not dataRow.HasChanges() before accepting them.
