OK,
This is a side-effect of M$'s declarative programming binge.
The
e.NewValues, e.OldValues only get populated when you are
using a datasource
control to bind to the GridView. Doesn't seem to be well
documented.

So, to get the value if you are not doing this, you need
just a little
something to get a reference to the GridViewRow control and
then go about
your business the old way.

Dim Row As GridViewRow = GridView1.Rows( e.RowIndex)

Dim Text As TextBox = Row.FindControl( "name")
