Can't get UpdatePanel to work in converted VS2003 to VS2008 (NET 3.5) website


I am trying to AJAX enable an older website, developed in VS 2003 (not AJAX enabled)

I have followed the conversion guide, backup, convert to 3.5 website, everything works and the site compiles without errors.

Now I want to AJAX enable the site but UpdatePanel doesn't work at all.

I tried to work on a existing page but that didnät work

Then I added a totally new webpage and put this "Hello world" code into it:


    <form id="form1" runat="server">
 <asp:scriptmanager id="ScriptManager1" runat="server">
			<asp:label id="Label1" runat="server" text="Label"></asp:label>

    	<asp:updatepanel id="UpdatePanel1" runat="server">
					<asp:label id="Label2" runat="server" text="Label"></asp:label>
					<br />
					<asp:button id="Button1" runat="server" text="Button" />

 And the code behind as follows:


	Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
		Label2.Text = DateTime.Now.ToString
	End Sub

	Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
		Label1.Text = DateTime.Now.ToString
	End Sub

 Even this simple page doesn't work.


Then just before my hair were getting grey, I fired up a brand new webiste in VS 2008, and put in the code above, and to my surprise the page works as a charm


So my wondering is now, do I have to manually to some fix to my older website to really enable AJAX to that site?

Thanks in advance

Take a look at the web.config that was generated for the new ASP.NET 3.5 site, and merge that with the upgraded site's web.config.  That should get your existing site working.
