OK, I found the answer. I can't delete this post, so to see what's up, [URL="http://p2p.wrox.com/asp-net-3-5-basics/69162-ch-10-updatepanel-design-view.html"] I typed the answer here then hit the wrong button and lost it.

The following happens both when I'm updating the page by hand and also on the pages I copy from the Source directory's downloaded files so I don't think I'm just mis-typing something , but ...

When I'm following the steps on page 328 to add the UpdatePanel to ContactForm.ascx, as soon as I wrap the <asp:UpdatePanel....> ajax control around the FormTable, the forms, text, and the rest disappear from the Design view of the page. I can still see the html when I'm using markup view, the control shows up in Contact.aspx, and it all shows up in my browser, but where's the design view gone to?

The previous Try It Out that had the timer/clock on the UpdatePanel didn't disappear from Design view. I've looked all through earlier parts of this chapter and can't find any warnings, so where's it all gone?

Thanks!

John

Added: OK, I just went and in markup view added a button OUTSIDE the UpdatePanel. It didn't show up in Design View. Then I went to design view (which was all blank) and added another button. It did show up in Design view until I edited the Text property of the second button at which time it also disappeared. Am I nuts or is this some kind of a feature in VWD?

By co-incidence, I am working on something similar, and so dug out the book. I note that Imar calls for the Update Panel to be added in markup.

It's a bug in Visual Studio....

Bug, feature, bug, feature. Who are we to tell what's what.

I'm just glad it wasn't something I did.

I did go back to the Try it out on page 324 and added the <style. . . . . .> block that the people at MSDN claimed causes the problem and am still able to see everything in design view. Oh, well.

Thanks,

John
