asp:Wizard inside of a asp:FormView breacks two-way databinding (Round 4)

Earlier this month, there was a posting about this without a definitive
answer.

If you place a Wizard inside a FormView's EditItemTemplate the bound fields
contained within the View will display the data from the fields to which
they are bound; yet they will return null values when the 'Update'
LinkButton is clicked.

The responder thought this might have something to do with naming
containers. If so, this is similar to an issue in Beta 2, Bug ID:
FDBK27772,
http://lab.msdn.microsoft.com/Produc...1-7e93b1d52077,
with naming containers (multiview, panel, etc) and fixed in a later build.

I checked, and it is works with MultiView.

Did the fix miss the Wizard or does this have nothing to do with naming
containers?

I want to use the built-in features of the Wizard rather than create my own
using MultiView.

Hi Doug,

Thanks for posting!

For the current issue, my understanding is that the Wizard control has the
same problem with the MultiView control when place it into the FormView
control. If I have misunderstood anything, please let me know.

In this scenario, could you please give me a simple demo which can
reproduce the current problem? This will help me to perform the same test
exactly. I appreciate your understanding!

In addition, the Wizard control is the naming container control. So if some
naming container controls is fixed, I think the Wizard control also should
be fixed. That's why I need perform some tests. Thanks for your
understanding!

Hi Yuan,

With the code below, try to update the Company Name with the Wizard and
MultiView examplex. The Wizard example post backs nulls.

Add a connection string to Web.config

<add name="LocalNWind"
connectionString="SERVER=(local);DATABASE=northwin d;INTEGRATED
SECURITY=sspi;" providerName="System.Data.SqlClient"/>

Multiview Example that works:

Hi Doug,

Thanks for your reply!

I have performed the test and reproduced the current issue. I think maybe
the bug is not totally fixed for all naming container control. I suggest
you open a new case to the Microsoft PSS. Since the issue maybe is caused
by the product bug, you will not be charged for the case. The Microsoft PSS
will supply the workaround or hot fix for the current issue.

For your reference, I attached steps to contact Microsoft PSS here: You can
contact Microsoft Product Support directly to discuss additional support
options you may have available, by contacting us at 1-(800)936-5800 or by
choosing one of the options listed at

Hi,

I am also using asp:formview - but instead of using the wizardstep I am using the control asp:multivew - I haven't perfected the whole process yet - but it does work - i.e. you can step through various views etc and pull data from a db.
If you want an example - respond to this post.
