Impement AJAX,

[codelinks]

Imagine this is my initial page DSIHome.aspx I need to implement AJAX in existing project, my requirement is……… I have a menu with sub menus,, which is again generated dynamically (XML). On clicking in any of the sub menus, I pass the argument to the URL , just like below location.href="DSIHome.aspx?hdnfld=" + obj + "&catName="+ catName ; this will initiate the postback and pass the values to the URL, and I can retrieve the form content based on the URL values using QueryString, my part here is to STOP postback, i need to implment AJAX and stop the postback happening while clicking the sub menu do u have any suggestion for this ?

The URL does not change when you use AJAX, so you need to rethink your whole approach. You could pass the values via the AJAX call and store them in jscript if you need them locally. What's on the page, that is, what sort of navigation are you hoping to replace with AJAX ?

the page contains treeview and 2 datalist, the data on these controls is loaded based on the values on the URL, as you said the values should be available locally , hope im conveying the problem in right words regards

OK, you should use ASP.NET AJAX for this, which will just wrap everything for you. Trying to populate those controls using your own JS is a PITA. If you put everything in an update panel, it will just AJAX it for you.
