Updatepanel wont call the control event method - ajax

I have a web page that has a masterpage. It has two drop downs. On Selected index chagne of dropdown1, I am calling the dropdown1_selectedindex changed. But nothing happens when I change the selection in the first drop down. I have placed the script manager in the master page. Update panel in the control page. The update panel encloses both the drop downs. Pelase help me. I am a starter and I thought this will be pretty straight forward. What am I missing here?
This is the .aspx

Thanks guys for trying to help.
I figured out the mistake in the trigger. In the trigger, eventname should be the event name SelectedIndexChanged rather that ddApplicationList_SelectedIndexChanged.
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ddApplicationList" EventName = "SelectedIndexChanged"/>
</Triggers>
sorry I lost the other link that gave me this answer.

AJAX ModalPopupExtender does not show

I have a website where I use AJAX ModalPopupExtender to show error messages. It works fine on one of the pages.
I had to create another page for a new functionality and there the same code does not work, whatever I do.
I have created some simplified code to test this in general, but so far no cigar. This is my code:
the html:
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<!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>xxx</title>
<link href="Styles/StyleSheet.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="form1" runat="server">
<div id="Test_Main" class="main">
<asp:ScriptManager id="ScriptManager1" runat="server"></asp:ScriptManager>
<table border="0" cellpadding="0" width="970px" >
<tr>
<td rowspan="1" vertical-align="top" style="height: 80px">
<div class="header">
<h1><asp:Label id="lblOrder" width="930px" runat="server" Text="Order" style="margin-left: 10px"></asp:Label></h1>
</div>
</td>
</tr>
<tr>
<td rowspan="1" vertical-align="top" class="auto-style1" width="970px" >
<asp:UpdatePanel id="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<uc2:TestOrder id="TestOrder1" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
</td>
</tr>
</table>
<div>
<asp:Button ID="Testbutton" runat="server" Text="Fenstertest" OnClick="Button_Test_Click"/>
</div>
</div>
<cc1:ModalPopupExtender ID="Testpanel" runat="server" BackgroundCssClass="ModalBackground" Enabled="true" TargetControlID="Testbutton"
PopupControlID="Panel1" CancelControlID="btnClose" BehaviorID="ModalBehaviourID">
</cc1:ModalPopupExtender>
<asp:Panel ID="Panel1" runat="server" CssClass="modalPanel" Style="display: none">
Test modal<br />
<asp:Button ID="btnClose" runat="server" Text="Close Modal" />
</asp:Panel>
</form>
</body>
</html>
and here is the code behind:
protected void Button_Test_Click(object sender, EventArgs e)
{
Testpanel.Show();
}
When I debug through the code, I see that the show method is executed, but then nothing is visible on the screen. When I execute without debugging, I see a short flickering, but no modal window.
My other page still works properly with that same method, this drives me crazy.
Does anyone see what is wrong here? Thanks for your help.
