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

Here is an example of one of the grids (i post only one column):

<asp:GridView ID="GridViewTransTab" runat="server" ShowFooter="True" AutoGenerateColumns="False"
                                    DataKeyNames="fName,main,startHour,endHour" OnDataBinding="GridViewTransTab_DataBinding"

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

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.

Add javascript to calculate total in onblur event of the textbox in EditTemplateColumn of Column2 in the GridView.

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?

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.

I may just be mean-spirited, but I really want to ridicule this question. I appreciate that you are new to asp.net, but just think a little bit. Who on earth would post a tutorial on building a complete social networking site. Anyone who would take the time to do that would simply build the site and call it "facebook" or "myspace" or "mySuperDuperOverDoneIdeaSpace".
