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.
