trying AJAX in asp.net 2.0

[Rahul]

I am trying the following thing in AJAX

<atlas:ScriptManager ID="scriptmanager1" runat="Server"
EnablePartialRendering="true" />
<aspropDownList ID="cmbBranchname" cssclass="Combostyle" runat="server"
/>
<br/>

<atlas:UpdatePanel ID="panel1" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<aspropDownList ID="cmbClientName" CssClass="combostyle" runat="server"
/>
<br/>
<aspropDownList ID="cmbProjectName" cssclass="Combostyle" runat="server"
/>
<br/>
<aspropDownList ID="cmbResourceName" cssclass="Combostyle" runat="server"
/>
<asp:Button ID="AddListBtn" runat="server" Text="Add" />
<br/>
</ContentTemplate>
<Triggers>
<atlas:AsyncPostBackTrigger ControlID="cmbBranchname"
EventName="SelectedIndexChanged"/>
<atlas:AsyncPostBackTrigger ControlID="AddListBtn" EventName="Click"
/>
</Triggers>
</atlas:UpdatePanel>

here AddListBtn trigger works AJAX way but cmbBranchname event doesn't work.

the dropdown is outside the update panel, so will it value is posted, it
display is not updated.

the update panel works by using ajax to post the form data, the server
then processes the page, and sends back the html that would be produced
by the panel (and its child controls). then client side, the inner html
of the panel is replaced with the returned html
