Ajaxified Button and Custom Validator Won't fire client-side validation

[Shawn]

Hello,

I'm having a lot of trouble figuring this out.  I have a web user control that loads inside a tabstrip tab.  This user control has a button on it.  When the user clicks on this button a RadPageView is loaded with another web user control as a modal popup window.  The modal window has several RadComboBoxes and a few RadTextBoxes.  I want to use a CustomValidator(s) to validate the combobox(s). If nothing has been selected the validation should fail.  The CustomValidator has the setting for ClientValidationFunction set for a JavaScript function.  I cannot get my code to execute the client-side validation function for the CustomValidator.

If anyone can help me figure this out I'd really appreciate it.  I've been struggling with this for the past week. 

Thanks.

The button and the validation summary are ajaxified within the RadAjaxManager that resides in the Master Page for the application:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnableAJAX="true" ClientIDMode="Static">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="btnAdd">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="btnAdd" />
                <telerik:AjaxUpdatedControl ControlID="pnlValidatorSummary" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

This is the markup for the RadWindow:

<telerik:RadWindowManager ID="rwmWindowManager" runat="server" EnableEmbeddedSkins="true" Skin="Metro" PreserveClientState="true">
    <Windows>
        <telerik:RadWindow ID="rdwAddNewAHU" runat="server" Modal="true" OnInit="rdwAddNewAHU_Init"
            Height="550" Width="600" Behaviors="Close" DestroyOnClose="true" ReloadOnShow="true" ShowContentDuringLoad="false" OnClientClose="OnClientClose">
            <ContentTemplate>
                <telerik:RadMultiPage ID="rmpAddNewAHU" runat="server" SelectedIndex="0">
                </telerik:RadMultiPage>
            </ContentTemplate>
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

<asp:Button ID="btnAddNewAHU" runat="server" OnClientClick="openwin();return false" Text="Add New AHU" Visible="false" />

<telerik:RadScriptBlock ID="rsbInventory" runat="server">
    <script type="text/javascript">
        function openwin() {
            window.radopen(null, "rdwAddNewAHU");
        }
    </script>
</telerik:RadScriptBlock>

This is the code I use to load the RadPageView with the popup user control:

private void LoadMyUserControl(string controlName, Control parent)
{
    parent.Controls.Clear();
    RadPageView pageView = new RadPageView();
    UserControl ctrl = (UserControl)LoadControl(controlName);
    string userControlID = controlName.Split('.')[0];
    ctrl.ID = userControlID.Replace("/", "").Replace("~", "");
    pageView.Controls.Add(ctrl);
    parent.Controls.Add(pageView);
}

protected void rdwAddNewAHU_Init(object sender, System.EventArgs e)
{
    int roleID = ApplicationInformation.GetRoleID();


    switch (roleID)
    {
        case 1: //Read Only
            btnAddNewAHU.Visible = false;
            break;
        default: //Suggesters and Approvers
            btnAddNewAHU.Visible = true;
            LoadMyUserControl(@"~/Modules/EspsMT/wucInventoryAddAHU.ascx", rmpAddNewAHU);
            rdwAddNewAHU.OpenerElementID = btnAddNewAHU.ClientID;
            break;
    }
}

I believe I may have found a solution to this problem myself.  It seems that if I use "RadAjaxManagerProxy" instead of the "RadAjaxManager" then my problems go away.  I believe this has to do with having WebUserControls in my application.
