TableAdapter -> ODS -> GridView issue

[Tina]

Once I link up a .xsd tableadapter to an object data source to a gridview
then put some template and button columns in the gridview I'm all set.
works and looks great. But if I need to modify the TableAdapter with some
new fields I have to replace the TableAdapter and it deletes all of my
custom columns.

Is there some way to get around this?
Thanks,
T
