.NET Forum / ASP.NET / General / March 2008using System.Web.Script; does not exist -AJAX installation
Hi, I have downloaded the ajax tool kit for vs 2005 but when I try to run it I get many errors. I think it is missing some assemblies. The first error is system.web.script namespace does not exist. I tried adding a reference as I was looking for adding system.web.extensions or system.web.script but could not find either under the .net tab. Thanks.  SignaturePaul G Software engineer. for VS 2005 first you need to download AJAX itself http://asp.net/ajax/downloads/ Scroll down to "Download ASP.NET Extensions v1.0" Geogre. > Hi, > I have downloaded the ajax tool kit for vs 2005 but when I try to run it I [quoted text clipped - 6 lines] > not find either under the .net tab. > Thanks. ok thanks, I just installed asp.net ajax 1.0 so thinking I should now be able to add the reference system.web.scrip or system.web.extensions SignaturePaul G Software engineer. > for VS 2005 first you need to download AJAX itself > [quoted text clipped - 14 lines] > > not find either under the .net tab. > > Thanks. The easiest way to get things set up is to create a new AJAX site in Visual Studio. There are numerous portions in the config file that you will have to copy over to the config in your application. If you have not set up anything in config, just copy the complete config over. Otherwise, you will want to copy over sections from the file. In <configSections>, the entire hierarchy of groups starting with system.web.extensions. In <compilation> the System.Web.Extensions and System.Web.Extensions.Design <add> nodes. That is a minimum set up. You should also consider: In <httpHandlers> the GET, HEAD line that points to extensions. The <system.webServer> hierarchy. and possibly the <runtime> hierarchy. After this, you should be running. The other option is to copy all of your pages into a newly created ASP.NET AJAX site, but that is more time consuming. SignatureGregory A.

Thanks, It looks like the sample website is working now, demonstrates all of the controls. So it looks like AJAX is a large selection of javascript librarys that can really enhance a website with minimal effort. That was my next question (how to impliment one or more of these controls into my web application) but I think it is has been answered above. My web application uses a single master page and all other pages are displayed in the placeholder on the master page so hopefully this will not create any difficulties in implimenting AJAX.

AJAX = Synchronous Javascript And Xml, so yes, it is a large number of JavaScript libraries. The ASP.NET AJAX encapsulates most of the workings so you do not have to write much code. There are other AJAX libs that require more code on your part. If all pages use AJAX, you can place the Script manager on the master page and it will encapsulate all of your AJAX controls, which will be in the content regions. It is a one time set up rather than each page, making things much easier. SignatureGregory A.

I placed an accordian on one of the pages and when I added a pane in the properties box I got the following error, <cc1:AccordionExtender ID="Accordion1_AccordionExtender" runat="server" Enabled="True" AccordionExtender is not a known element. I do not have a script manager on the page so is this why I get the error? I will place the Script manager on the master page as suggested since I think all the pages will use AJAX.

If not, you have to put them in the page. There has to be a way to link to the bits, either through config or through references in your page. Here is how I learned enough to refurb sites for AJAX. First, open your website. Then create a new AJAX site in teh same solution (you can delete it later). Any time you have errors, try the same thing in the AJAX site and then compare. You will usually find the solution by examining the top of the page that is having issues. What this teaches you is priceless, as you start to understand how they are "tricking" the application to use these new controls. SignatureGregory A.
