how do I access data on client side with ajax

hello. I have an mdb that I want to use to popluate some textboxes with out postback or waiting for IE to reload.

I am using easylist box that gives me the record ID but I want to use that ID to pull data from the MDB with out reloading the IE.

can someone link me in the right direction?

You should issue XmlHttpRequest on some Javascript event (say, button click or focus removed or whatever), which will pass your ID to the server side and will get the response, which you should dynamically insert into the TextBox you want (javascript, client side again).

This is th schema in general.

You can find a lot of free books about AJAX on the net, ex.: http://paperolli.com/default.aspx?keyword=ajax
