Ajax ComboBox not displaying item list correctly

tomturner22 · July 26th, 2010, 11:25 AM

I'm using ASP VB .net 2008 and am just now venturing into the world of Ajax. I've tried a few different controls and they are working great. But, the ComboBox is giving me problems.

When it is first rendered it looks fine - pretty much like a standard DropDownList. But, when I click the down arrow to expand the list, the list is not connected to the original box - it shows up at the bottom of the page, and depending upon where the page is scrolled will show up only partially or not at all.

Hope that makes sense - sorry I don't have a screen scraper so I can show the behavior.

I've done something wrong, just don't know what - - Any Ideas??

Thanks
Tom

HTML Code:

    <tr>
       <td class="cells1" valign="top">
             <asp:Label ID="lblRace" runat="server" CssClass="caption1" Width="41px" Height="6px">Race</asp:Label>
       </td>
     <td class="cells1" style="width: 19px">                           
       <asp:ComboBox ID="cmbRace" runat="server" AutoCompleteMode="SuggestAppend"  
                                BorderStyle="Solid" DropDownStyle="DropDown" AutoPostBack="true"  
                                 Visible="True">
