dynamic html production to call ajax post via javascript

I am maintaining a page that creates html (not server controls) elements dynamically and when one changes I need to call the ajax postback. Is that possible? The page that is created can't know ahead of time that it will need to post through ajax....

So long as you add a client-side Event handler to your html control when you create it, yes, you can wire it up to make asynchronous requests:http://www.mikesdotnetting.com/Article.aspx?ArticleID=40. Note, the methodology outlined in the article doesn't make an ASP.NET Ajax request or postback. It differs in that it only makes a call to the server-side method you want to invoke. This can be better than using ASP.NET Ajax, in that you aren't recreating all the controls on the page.
