databinding issues... Take two

Hello hello,

Ok so here's (another) ASP.Net 2.0 question...

I've got a GridView that's bound to a table that has several lookups:

Field A, B and C are foreign keys. B & C's values depend on A so if A changes, so must the possible values for B & C.

I store A's value in a Session variable. This works out nicely 'cause in 2.0, you can set Select Parameters to values of Session variables. However -- when I change the value of the Session variable, the following error occurs:

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

I'm guessing that it's due to the following problem: the dropdowns I use for looking up the values of B & C are not happy about re-binding while the row is being edited, either because of the SelectedValue binding or simply because it will not re-bind to the datasource I use for the lookup.

Any idears?
