>My question is how to determine if the record is being added, is there a status property for the current row that can be checked? is the original value of the control stored someplace that can be checked (if adding the original field would be blank). The field will have a rule that enforces there to be a value; therefore, it should always have a original value if they are editing the record.

When you add a new record via the business object you can examine the business object's DataRow.RowState property. If it's been added, the value is set to DataRowState.Added.
