Gridview Cell Values durign RowUpdating Event

I have created a gridview that is dynamic and binds the grid dynamically based on a table selected in a dropdown. I have worked through most of the issues like dynamically creating the update, delete statements etc except for one problem I'm having in retrieving the cell value while in the rowupdating event.  I can retrieve it every where else; but not in this event.  I am not setting up an item template or assigning names so as to keep the process very dynamic where it can be run on one of 25 tables selected all with different fields where I only define the fields in the select, update, and delete statements with generate fields=true.

The code follows but  GridView1.Rows(rowIndex).Cells(i).Text  is always empty if your on the row being updated.  And this  e.NewValues(0).ToString()  is always an error so I am unable to get the value to plug into the dynamic update statement.

If you on a different row; no problem it will return the value.
Thanks for any help.
