Answer 1

JQuery is for HTML Manipulation (and animation, event handling and Ajax) on the client so you won't be able to use it in your code behind but only on the client !

Now using JQuery is simply adding a reference to it in your html like

<script src="path to jquery.js" type="text/jajascript"></script>

then the js file will be loaded on the client and you will be able to use the JQuery object often used with its alias $.

Answer 3

Jquery can be a very useful extra functionality for your application, it will work clientside as you must have realized from your finding that it is a JavaScript library.

I often integrate it with .net applications and that works great. I generally just add it in the aspx-file, not in code-behind, but that should be possible too, if needed, by using the ScriptManager.RegisterClientScriptBlock-functionality.

JQuery is very well documented. Take a look at http://docs.jquery.com/Tutorials When you get the basics, you will soon get the point how and if you can use it for your features.

Answer 4

The example you link to shows somebody using the ScriptManager class to output script to the client, where it runs.

This is a tool that ASP.net provides to simplify outputting dynamic <script> tags - it does not run the javascript on the server at all.
