Greetings Kevin,

Should there be a check to see if DE.Value is null in the for each loop and set to System.DBNull.Value if it is?

Regards,

E.R.

>>>The table this is saving to has a date field that accepts nulls. I'm editing the row that had a null date to begin with. After editing a field (not the date field in question) I get the ArgumentException while trying to update. I tried checking the date field before saving and setting it to System.DBNull.Value, but that doesn't work.
