2.0 beta 2: Disappearing Controls

[clintonG]

Hello Fellow Masochists ;-)

In the MasterPage I've used a control (LinkButton1) in the 'header' region
to function as a tab that displays another control (LinkButton2).
LinkButton2 is located within a panel (Panel1) and I control the display of
LinkButton2 by modifying the Panel1.Visibile property.

When LinkButton2 is clicked it loads content as expected but LinkButton2
disappears after its click event is raised and the page is posted back to
get and load the content page into the MasterPage ContentPlaceHolder.

LinkButton2 appears in the Trace control tree and when displayed by the
LinkButton1 click event LinkButton2 has Render Size and View State size
values. When LinkButton2 is clicked to load the content page LinkButton2
disappears from the HTML source, it is not displayed by the UI and its
Render Size and View State values are zeroed out of the Trace control tree.

I've tried using the FindControl method and creating a Property both of
which will return values for the LinkButton2.ID and
LinkButton2.NamingContainer but I can not access or set
LinkButton2.Visibility or other properties because the control has somehow
disappeared. A similar behavior occurs with the SiteMapPath.

What could I be missing?

State size values. When LinkButton2 is clicked to load the content
page LinkButton2 disappears from the HTML source, it is not displayed

Without a repro, can't say. How is the LinkButton2 being added? In the
designer or dynamically? Sounds right off like the Panel is not visible any
longer, but as I say, can't say for sure without debugging.

Thanks for responding.

The link buttons and panel control are defined in the MasterPage.

I have no idea how to debug this runtime anomaly other than observation
using trace which is why I've posted seeking insight from others. What
debugging approach would you suggest?

I hesitate to offer any suggestions without knowing the details of the
implementation. I generally use Windbg for debugging such things because
it's more low-level than VS.NET. However, VS.NET 2005 makes it easier.

I'm running a much later build than beta 2. Have you tried this with the
August CTP? There were some bugs in the implementation of Master Pages in
beta 2 that were corrected shortly after it was made available.

No kidding? Bugs? I am shocked
I'll go check MSDN Feedback for any reported bugs in MasterPages. Where did
you learn of these bugs?

Good grief, Clinton. You're a developer. Surely you realize that there are
bugs in a beta product!

But I am a burnout and the truth is I didn't even think of checking MSDN
Product Feedback although I have posted quite a few suggestions and reported
several bugs myself and I don't have a good grasp on referencing controls in
the MasterPage from content pages yet which is why I haven't been able to
debug this runtime anomaly yet. Once I can get or set properties on controls
in the MasterPage I'll be able to deduce why the LinkButton controls are
being removed from the ViewState yet remain in the control tree.

BTW -- I downloaded the August CTP tonight and then promptly sent it to the
Recycle Bin after learning Microsoft has announced a RC1 that they state
will be available this month.

I'd at least test it with the CTP release. It's considered RC0.
