I have a form in which the controls are bound to an alternate table in the biz object. For example, the biz object is OfficeNote and the table is AssignmentNote. I have a text box which has a BindingSource of "OfficeNote" and a BindingSourceMember of AssignmentNote.CompletedBy. When the user clicks on the button to "Complete" the note, I have a line of code in the click method as follows:

     this.txtCompletedBy.Text = mmAppDesktop.UserMgr.UserID;

When I save the row, the CompletedBy column is not filled in.

I ended up changing this to get a reference to the DataRow and assigning the value to the datarow column but I don't understand why assigning the value to the control's text property didn't work? Did I miss something?

Thanks.
