I have a server with .Net 2.0 sp1 installed and have no ability to install the AJAX extensions on the server.
Is there anyway I could work around this to incorporate ASP.NET AJAX functionality?
回答1:
You don't need to install the AJAX extensions into the server's GAC.
You can locally reference System.Web.Extensions.dll from your applications BIN folder....I've done it half a dozen times.
Copy that DLL to your projects local bin. Reference it from your project. Remember to deploy the DLL when you deploy, and you are set.

Theres always prototype and jQuery for AJAX calls.
Both of which are perfectly valid for making Ajax calls to the server, despite Jonathan Hollands persistence (and his down-voting of everyone else's response) to the contrary.
MS now packages jQuery with Visual Studio, so there is no interoperability problem.
Please remember that the server has no knowledge of controls created on the client side, and you will have to take the extra steps to persist any data (via ajax calls) to the server.

If you can't install AJAX extensions, you will have to manage the AJAX calls yourself. It's absolutely possible, since AJAX Extensions just wrap the meat of AJAX. Read up on XMLHttpRequest and you'll find many examples.
Here's a good site with examples. http://www.fiftyfoureleven.com/resources/programming/xmlhttprequest/examples

Note that most of AJAX is done on the client side (in the browser) in Javascript.
While there are some server-side libraries to make responding to a AJAX query easier, for the most part they are unnecessary. Any server technology that can server a web page to a browser can handle an AJAX request just as well.
回答5:
Microsoft ASP.NET AJAX is not the only way to implement AJAX Functionality. jQuery and Prototype are two popular javascript libraries for working with AJAX, regardless of server platform.
If you're tied 100% to Microsoft ASP.NET AJAX, then you may need to download it and install the DLL manually to your local project.
