Complete posback for first time with RadAjaxPanel

[nav100]

Hi,

I am experiencing problem with RadAjaxPanel. It does complete posback when selected index changed of RadComboBox for the first time. It works fine after. What could be the problem? Here is my code. This code is in User Control.

Thank you..

<telerik:RadAjaxPanel ID="radAjaxPanel1" runat="server" LoadingPanelID="radldpnlContactInfo">
    <asp:Panel ID="Panel1" runat="server" Visible="False">
        <table id="Table1"><tr><td>
                                <telerik:RadComboBox ID="RadComboBox1" runat="server"
                                    AutoPostBack="true" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
                                </telerik:RadComboBox>
                            </td>

                            <td valign="top">
                                <br />
                                <asp:Button ID="button1" runat="server" OnClick="button1_Click" Text="Test1"
                                    /><br />
                                <asp:Button ID="button2" runat="server" OnClick="button2_Click" Text="Test2"
                                     />
                            </td>
                        </tr>
                    </table>
</asp:Panel>
</telerik:RadAjaxPanel>

Hi Nara,

Could you please let me know how the UserControl is loaded on the page? If they are dynamically added please make sure that they are added in Page_Load or Page_Init events.
