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.

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

Hi Steven,

What is the status on this?

I saw this was an issue in Beta 2, Bug ID: FDBK27772,
http://lab.msdn.microsoft.com/ProductFeedback/ViewFeedback.aspx?FeedbackID=b104c
bc3-8a55-4752-8c11-7e93b1d52077,
inside naming containers (multiview, panel, etc) and fixed in a later build.

If you suspect this to be the case for the wizard, why didn't FDBK27772 fix
it also?

Thanks,

Doug
