[Solved] UserControl not hit Page_Load in RadWindow

[Nuno]

Hello, i had spend a lot of time, and for some reason the UserControl uc:MultiContactSelector
never hits his Page_Load where its data is loaded, it always appear empty.
I have no errors either compiling or runing
The User Control its working properly in other pages without RadWindows and inside UpdatePanels.

Can you give me some hint why it never hit the User Control Page_Load.


<telerik:RadWindow Title="Event Info" EnableEmbeddedBaseStylesheet="false" EnableTheming="false"

        EnableEmbeddedSkins="false" ID="rwNewEvent" Modal="false" runat="server" Width="780px" Height="440px"

        VisibleStatusbar="false" Behaviors="Close">

        <ContentTemplate>            

            <asp:UpdatePanel ID="upNewEvent" runat="server" UpdateMode="Conditional">

                <ContentTemplate>

                    <div class="form m5_rw_form">

                        <uc:FormTextbox ID="txbSubject" Label="Title" runat="server" />

                       <uc:MultiContactSelector runat="server" ID="mcsEventContacts"  />

                    </div>

 

                    <asp:Panel ID="Panel1" CssClass="m5_rw_actions" runat="server">

                        <asp:LinkButton CssClass="btnAction" ID="btnSaveEvent" Text="Save" OnClientClick="return okRadWindowNewEvent();" OnClick="btnSaveEvent_Click" runat="server" />

                        <asp:LinkButton CssClass="btnAction" ID="btnCancel" Text="Cancel" OnClientClick="return cancelRadWindowNewEvent();" runat="server" />
