Hi...
You also drag this....
  <asp:ScriptManager ID="ScriptManager1" runat="server">
                    </asp:ScriptManager>

Register txtSearch as AsyncPostBackTrigger control in UpdatePanel as:

 <asp:UpdatePanel ID="upanel" runat="server">
        <ContentTemplate><asp:TextBox ID="txtsearch" runat="server" CssClass="autosuggest" class="ddl"
                                                    Style="width: 400px; height: 22px; border-style: ridge; background-color: #EDEDED;
                                                    z-index: 1000" ontextchanged="txtsearch_TextChanged" AutoPostBack="True"  ></asp:TextBox>
        </ContentTemplate>
        <Triggers>
          <asp:AsyncPostBackTrigger ControlID="txtsearch" />
        </Triggers>
 </asp:UpdatePanel>

Sometimes server controls don't work in UpdatePanel and we need to register them as we have done in above code. Let us know if it helped you or not.
