#4 ajaxToolkit:ComboBox displays drop down list items away from the control

[Anonymous]

I have the following code in my web page

    <!-- ==================  Country Selection Field ====================== -->
   <div class="RegFieldsCountry">
   <asp:Label ID="CountryLabel" runat="server" AssociatedControlID="Country" CssClass="RegCountryLabel" Text="Χώρα" />
   <ajaxToolkit:DropDownExtender ID="DropDownExtender1" runat="server" 
      EnableViewState="False" TargetControlID="Country" Enabled="False"/>
   <ajaxToolkit:ComboBox ID="Country" runat="server" CssClass="RegComboCountryEntry" TabIndex="8" Width="125" ValidationGroup="SetUserValGroup" ToolTip="Επιλογή χώρας" DropDownStyle="Simple" OnSelectedIndexChanged="Country_SelectedIndexChanged"  TargetControlID="Country"/>
   <asp:RequiredFieldValidator ID="RequiredRegComboValidator" runat="server" ControlToValidate="Country" ErrorMessage="Η επιλογή χώρας επιβάλλεται." ToolTip="Η επιλογή χώρας επιβάλλεται." ForeColor="red" ValidationGroup="SetUserValGroup" CssClass="RequiredValidator">*</asp:RequiredFieldValidator>
   </div>

What I get from that is a ComboBox in the exact place on page inside of a Fildset, and a Drop Down List far away in right - down of the page outside of the Fieldset.

What I need is to have the Drop Down List just below of the control.

Is there someone to assist me on this issue?
