TableAdapter won't pull correct data for update method

I am working on an asp.net application that will allow my company to pick an item from a datagrid, and then print the list of items selected out with there corresponding locations within our warehouse.  I took the approach of programming this like a shopping cart in that a clerk can search for an item and it's locations are displayed in one gridview, if they select a particular row, it's contents are added to another gridview.  The problem I am having is that I can't seem to update this second gridview, which is the Editable GridView on Matt Dotson's MSDN blog.  The update method I call works correctly but it doesn't recognize that I've changed the data in the Textbox.

Example is if the default quantity was 0 and I change it to 12 in the textbox, once I push the update button it updates with the quantity as 0 and not 12.  I have verified this much by stepping through code within the debugger.
