Problems Updating GridView when bound to datatable

I am having problem updating when GridView is bound to datatable.
Can enter edit mode fine but when I extract new and old values they are
the same (ie. the old and new values are exactly the same!!!)

any help would be greatly appreciated.

here is my code:

Dim cell As DataControlFieldCell =
gridSubscribers.Rows(e.RowIndex).Cells(1)
gridSubscribers.Columns(0).ExtractValuesFromCell(e.NewValues, cell,
DataControlRowState.Edit, True)

cell = gridSubscribers.Rows(e.RowIndex).Cells(2)
gridSubscribers.Columns(1).ExtractValuesFromCell(e.NewValues, cell,
DataControlRowState.Edit, True)

cell = gridSubscribers.Rows(e.RowIndex).Cells(1)
gridSubscribers.Columns(0).ExtractValuesFromCell(e.OldValues, cell,
DataControlRowState.Edit, True)

cell = gridSubscribers.Rows(e.RowIndex).Cells(2)
gridSubscribers.Columns(1).ExtractValuesFromCell(e.OldValues, cell,
DataControlRowState.Edit, True)

Dim records(e.NewValues.Count - 1) As DictionaryEntry
Dim oldRecords(e.OldValues.Count - 1) As DictionaryEntry
e.NewValues.CopyTo(records, 0)
e.OldValues.CopyTo(oldRecords, 0)

Have you defined the datakeyname property?

Hope this helps you

I figured it out. The grid was rebinding before the row updating
event. I just changed the code so it binds after the update.
