Hi John,
Welcome to ASPNET newsgroup.
As for the using FormView control together with Wizard control to perform
data inserting problem , based on my understanding, it is likely due to the
Wizard control itself is a Naming Container which cause its child control
can not be recognized by the FormView's template(only direct nested Control
will be recognized....)...
So far I'm thinking use Control Parameter to map sub control and the insert
parameters, but seems it'll be also a bit hard. Anyway, I'll perform some
further test to see whether there is any other means to workaround this and
will update you soon.
Thanks,
Steven Cheng

| I posted this yesterday with a different email address. I am reposting
with
| my fake-address as given to me by Microsoft so that I can be guraranteed
a
| response from a support representative. Sorry for the repost.
|
| I'd like to make use of the asp:Wizard control to present a step-by-step
| guided experience for my user to fill out a complicated data-entry form.
|
| I'd like to make use of two-way databinding provided by the asp:FormView
| control to drasticly reduce the number of lines of code I need to write.
|
| But when I combine those two controls, databinding breaks. Please see the
| example below. The database in this example is a simple access database
with
| a single table My real life example is way to complicated to describe
here,
| but this simple case reproduces the problem.
|
| If you run through the wizard, clicking Finish causes a record to be
| inserted with null values in all the fields. What I don't show here, is
if
| you strip out the wizard control, everything works fine.
