I have added the update panel and scriptmanager as described in listing 19-4. It is not working! That is when you hit button 2, you still get the full postback, not the listing 19-7. I even downloaded the sample code (in C#). Same result. Is there some sort of security setting or something else I need to do to get AJAX working?

As a side note, I'm not really sure it's a good example. The jist of it seems to be, "wow, the first edit box does not change when you hit the second button that is inside the updatepanel". But that would be the case if there was not such thing as AJAX. There are two seperate button handlers!

Thanks.

To add to the last post.... Perhaps I'm missing something here.
How was the output in listing 19-7 generated? Simply a view source?

It does appear that button2 behaves differently (result returns faster), but it also appears that if you look at the event Page_Load, it's hit everytime too. What's going on?

Thanks.
