FINALLY! OK, here's what I did to resolve the issue:
1) From the Build menu I chose to Build my test project. Building/Rebuilding the solution did NOT do the trick. I had to explicitly choose my test project name from the Build menu.
2) Then I selected Test ->Windows -> Test View. This showed my web performance AND coded tests.
Hope this helps others who have this issue!

 Isn't it amazing how you can spend hours/days failing to solve something, then within 10 minutes of giving up and posting a question about it, you suddenly figure it out for yourself! (Happened to me on more than one occassion.)

Hi,
I have form with 3 tabs,
i each one i have a grid.
My problem is - sometimes i'm getting this error when i'm pressing the EDIT button.
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
At the first time nothing happens,
but at the second click i'm getting the above error
Can someone please please help me?
Thanks;
Tamir

Can you add the code behind, if you are adding a control dynamically (something like Controls.Add(myControl);), not doing this at postback is the most likely cause of your error (as the exception states).

I'm not using this command.
Controls.Add(myControl);

This is considered rude. See the FAQs and guidance stickies at the top of the forum.
I've told you what the problem probably is (dynamically added controls), and asked for the code. I am 80% certain you are adding a control in code-behind that is being accessed in postback before it is getting re-added, but without the code it is impossible to tell.

Forgive if it is not a right place to post this question
See Am developing a web based social networking website in ASP.NET say X-Netowork.. This is connected with VSS and also we are having number of portals with minor changes in logo and some labels say for ex Y-Network, Z-Network etc.
I am facing a problem every week end to integrate the changes done in X-Network to Y-Network and Z-network..
Is there any other way to do this easily without manual integration
Expecting your help

Thank u for your reply
We are developing a social networking website for some clients.
Basic website xnetwork
And we are having ynetwork, znetwork same as xnetwork.
But still the developing is going on with xnetwork.. Each and every change done in xnetwork has to be updated with ynetwork and znetwork... My question is "Is there any way to handle it without manual work"

Unfortunately, it depeds on how you designed your website. e.g if you want these sites to share a Data Layer , what you can do is that create a Data Layer and a Business logic layer as DLL's at the end when you deploy you will not need to do anything but deploy the dll's and nothing else. So i am not sure what part of your website is a maintanance nightmare , but what you are experiencing means that its time to componetise your functionalities in your website.

You probably should just start using resx files. That will handle changing of images and labels. If you actually have different pages, or different functionality on the same page in different sites, then it gets much more complicated.

1) Of course not, Microsoft does not make software for Enterprise applications
2) Its up to you to decide what data and what modules. How the hell do we know?
3) You want more than the project template provided by Visual Studio?
4) See #3

Is there any way we might get an idea of what kind of Enterprise level application? Perhaps we could ask Mr. Spock?

1. It is like Kellog's Special K, it can only help as part of your calorie controlled diet.
2. The architecture should fit the application needs
3. All open source projects are a possibility
4. The ones that fit your need best.

This is a ridiculous question: if you want to create a social networking site you're going to have to a) learn to program and b) figure out how to design an application that does what you want and c) dlearn how to research and use google. Just like the rest of us only you seem to want to cut out the years of hard work and learning that we all put in.
