I have an iis 6.0 2003 server but have no idea how to install?

and do I update all the scriptpaths in my project?

If you install the 3.5 framework on your server and target those assemblies in your site's web.config, it automatically uses the 3.5 version of ASP.NET AJAX.  ASP.NET AJAX is included in the base 3.5 framework.

ok I did that. but how can I be sure that the javascript belongs to 3.5 not something else ?

 there is no header in axd files....

it just goes like

 >>>>>>>>>>>>>>>>>>>>>>>>

function WebForm_PostBackOptions(eventTarget, eventArgument, validation, validationGroup, actionUrl, trackFocus, clientSubmit) {
    this.eventTarget = eventTarget;
    this.eventArgument = eventArgument;
    this.validation = validation;
    this.validationGroup = validationGroup;
    this.actionUrl = actionUrl;
    this.trackFocus = trackFocus;
    this.clientSubmit = clientSubmit;
}
function WebForm_DoPostBackWithOptions(options) {
    var validationResult = true;
    if (options.validation) {
        if (typeof(Page_ClientValidate) == 'function') {
            validationResult = Page_ClientValidate(options.validationGroup);
        }
    }
    if (validationResult) {
        if ((typeof(options.actionUrl) != "undefined") && (options.actionUrl != null) && (options.actionUrl.length > 0)) {
            theForm.action = options.actionUrl;
        }
        if (options.trackFocus) {
            var lastFocus = theForm.elements["__LASTFOCUS"];
            if ((typeof(lastFocus) != "undefined") && (lastFocus != null)) {
                if (typeof(document.activeElement) == "undefined") {
                    lastFocus.value = options.eventTarget;

I don't know ..the thing is we are trying to eliminate the errors on the webpage and doing some search engine optimization.

that's why I really wanna debug the ajax framework .Do u know any side affects fo seo ?

AJAX in general can be an SEO nightmare, depending on how it's implemented.  What specific problem are you having? 

Look my friend, with all respect... do you know how to install the ajax library yes or no?... the question is very simple: there is a download on the asp.net ajax site that is name ajax library 3.5...it is a zip file, but there is no indication on where to place its contents... can anybody please tell where to place its contents?

Many thanks 

ASP.NET AJAX is built into ASP.NET 3.5 and higher.  There's no need to install anything other than the framework.

Hi ,

I agree with Dave . If your application is running on .Net 3.5 framework and you are having VS 2008 then Asp.Net Ajax functionality is inbuilt. There is nothing you have to do.If you select new website as template , the corresponding web config will automatically reflect the sections required for asp.net ajax.

That said , if you are having VS 2005 and .Net 2.0 framework then probably you will have to install the asp.net ajax framework.If you are looking for converting an existing website into an ajax enabled website then you need to add the respective dll's and modify the webconfig file manually.

So please let us know which framework your application is running on .

Are you folks talking about the basic AJAX tools like UpdatePanel, or the ToolKit (e.g. CalendarExtendar)?

I have VS 2008 Pro and .Net 3.5 SP1, and I have the basic tools, but can't seem to find the ToolKit controls.

What am I missing?
