RadComboBox LoadOnDemand Problem

[Muhammad]

Hi,

I am using Radcombobox feature LoadOnDemand. In my radcombobox I have a label, textbox and a button control but when I try to click on a button the post back occurs but my onclick event doesn't fire.

Is this the problem because I am using LoadOnDemand ?

Any help would be greatly appreciated.

<telerik:RadComboBox ID="rcbProducts" runat="server" Width="300px" Height="300px" EnableLoadOnDemand="true" 

                                   DataTextField="ProductCodeAndDesc" DataValueField="LogisticProductKey" Font-Names="Arial"

                                   Font-Size="XX-Small" Skin="Windows7" EmptyMessage="- please select a product -"

                                   Filter="Contains">

                                   <ItemTemplate>

                                       <table>

                                           <tr>

                                               <td>

                                                   <asp:Label ID="lblProductName" Text='<%# Bind("ProductCodeAndDesc") %>' runat="server"></asp:Label>

                                               </td>

                                               <td style="text-align: right">

                                                   <asp:TextBox ID="txtIntervalDays" ValidationGroup="vgNumeric" Width="50px" MaxLength="5" Text='<%# Bind("RepeatIntervalDays") %>'

                                                       runat="server"></asp:TextBox>

                                                       <asp:Button ID="btnSaveIntervalDays" Text="Save" OnClick="btnSaveIntervalDays_Click" runat="server" />

                                                       <asp:Button ID="btnTest" Text="TEst" OnClick="btnTest_Click"  
runat="server" />

                                                   

                                               </td>

                                           </tr>

                                       </table>

                                   </ItemTemplate>

                               </telerik:RadComboBox>
