The content you requested has been removed. Don't forget about AlternatingItem! If my suggestion works and you still want to assign the DataMember dynamically, you could try Me.tripsDataSet.tripsTable.TableName, which contains just the name of the table as a String.

The ItemCreated event takes place as each row is initially added to the Datagrid, and the ItemDataBound event occurs as the data is bound to each row. I'd still very much appreciate it if you could answer my last reply to your post though.
