Editable datagrid with dynamic table data

Posts: n/a
Not so easy!!! I have learned that I can't have an editable datagrid
using AutoGenerateColumns=true. OF COURSE NOT!! That would be too easy.
So how the heck do I do it?

I have a simple Web Form that dynamically populates a listbox with some
Oracle database table names ("select table_name from tabs" FYI). I then
have my datagrid dynamically show the data from ANY of the tables
listed ONCHANGE of the listbox. I just set AutoGenerateColumns=true on
the DataGrid, ExecuteReader, then Bind. Finally I wire-up the event
handlers for Edit, Update, Delete and UN-editable grid.
Perfect - time to go home right? WRONG! That's why they pay us the big
bucks (??). I actually have to do some coding.

However, I can't find one useful article on how do use Template columns
and EditItemTemplates and ItemTemplates. Any help greatly appreciated.
