Update Panel not refreshing

I have an update panel in a grid template that has a parent and child dropdown.  When the user selects a value from the first, I want the update panel to populate the second dropdown but not refresh the rest of the page.  

I can only get this to even load the second dropdown when I set AutoPostBack="true" in the 1st dropdown.  But this makes it refresh the whole page.  I tried removing that then setting the Update page UpdateMode="Always", but that doesn't do anything at all.  Any idea what I'm doing wrong here?
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
                  <ContentTemplate>                 

                    <cc2:OboutDropDownList ID="ddGenre" runat="server" Width="100"
                         DataSourceID="dsGenres" DataValueField="genre" AutoPostBack="true"
                         DataTextField="genre" AppendDataBoundItems="true">
                          <asp:ListItem Text="...Genre" Value="All" Selected="True"></asp:ListItem>
                    </cc2:OboutDropDownList>

I'm still stuck.  I really don't know what the issue is.  My whole grid still refreshes every time I change ddGenre.  You can put an update panel in a grid template right?  Please help!  I've attached the code for the entire page so you can see.
