Button not performing Asynch Postback

Full of frustration here.  I have a very simple page that works by itself.  But, when I add it to another project, it *works*, but instead of doing the asynch postback, I'm getting a full post back.  I don't even know how to troubleshoot this.  The code is good, so something about my configurartion must be wrong...but what?

I've tested a lot of different things...for instance, I've tried putting a GridView in the update panel and guess what....the Header Sort works asynchronosly.  On the same page, the Button does a full post back.  Sigh.  Where should I start digging to find the culprit?

Here is the code -


---------.net page-------
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="test.aspx.vb" Inherits="HSE.test" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdatePanel runat="server" UpdateMode="conditional" ID="updatePanel">
            <ContentTemplate>
                <asp:Label runat='server' ID="label1" />
                <asp:Button runat="server" ID="button1" Text="update" OnClick="button1_Click" />
            </ContentTemplate>
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="button1" />
            </Triggers>
        </asp:UpdatePanel>
    </div>
    </form>
</body>
</html>




-------code behind-----
Public Partial Class test
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Protected Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
        label1.Text = Now.ToString()
    End Sub
End Class

So...I continue to dig.  I put that grid in my test code and checked what was generated when the page was created.  Here is what my button looks like:

<input type="submit" name="button1" value="update" id="button1" />


And here is what one of the heads of the gridview looks like:

<a onclick="javascript:__gvPlantOpsview.callback(&quot;0|0|/wEFB0NvdW50cnnwBCUCC72UOdxtKslQe3oHsM8F0g==|&quot;); return false;" href="javascript:__doPostBack('PlantOpsview','Sort$Country')">Country</a>



Looks like Ajax is doing the right thing with the grid headers, but not with the button....weird.

Sometimes a chainsaw is the best approach.  After slicing a scalpal through my web.config and references ad nauseum, I did the sensible thing and started my project over....problem solved.
