I've tried for some time now to sort out a problem with AJAX on our site and I'm more or less desperate to sort this out once and for all.

After a little hustle I got AJAX running but in the meantime I must have messed up some handlers becuase since then some parts of the edit mode has stopped working (the "Start"-tab - online center or whatever it's called -, the search function in the top right corner and the links option in the reports area to mention a few). I've tried to get them back but with no success. Either AJAX works or I loose the functions I mentioned above.

Now I've created a new site where I can implement AJAX from scratch and I'm hoping to be able to copy those sections of web.config to our real site. So to begin, what's the easiest way to implement AJAX on the public templates? I can't find any notes on it.
