Hi all,
I followed first walk through sample from
http://ajax.asp.net/docs/tutorials/IntroductionUpdatePanel.aspx to create my first testing page, The problem is after I clicked that botton, it still trigged a postback. Do I miss something?
Following is my code:
ASPX Page
<%@dotnet.itags.org. Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %

Hey,
For your script manager, add EnablePartialRendering="true", and for your updatepanel, add Mode="Always".
Neither of those things should be necessary. (They're both the defaults.) Also, it's "UpdateMode" now (not "Mode" as it was in early CTPs).
My guess is that something's wrong in your web.config... did you start from the "ASP.NET AJAX-Enabled Web Site" template? Are there any JavaScript errors on the page when you first load it?

You are right, I didn't start a new web site with "ASP.NET AJAX-Enabled Web Site" template. I adjusted web.config manually, and it works.
