I have a ASP.NET web-site built on 2.0 framework. This works fine on IE and firefox. Now I do few ammendments to the web-site and build it on 3.5 Framework.

Is it necessary for user to install Fx 3.5 runtime?
I am coding with VB.Net 2005. I have an issue popping up a message box on the client's side. The message box works well when running the application on my local machine, but when the site is hosted on the server, there is an error showing a conventional message box()in vb.net 2005 on the client's machine.
How the ilusion of causing site to change content from server side is done? Let the example be gmail chat or chat on facebook. Or even new message sign on stack overflow.Is it done by http://en.wikipedia.org/wiki/Comet_(programming) ?

I have tried every single method in almost every post available on both Bing and Google. And I still get this error.I thought it was something in my website or web.config, so I opened up VS2008, selected to create a new ASP.NET Website and let it go..Here is the default.aspx page and web.config created by VS2008. Without modifying anything other than chaning the website properties to .NET 3.5 instead of .Net 2.0, I still get the error on this website when I hit F5. I have other websites with the ajax update panel and script manager on this server that work fine and have tried the web.config from them on a new project. But any new projects still do not work.I have verified that the settings for the working project as well as this new project in IIS are the same. Can anyone tell me why I am getting this error and theSys Undefined error?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript"> function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
[code]... Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?
