The aspx page does not see the user control.

Any help would be appreciated.

I have the following aspx page:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using PrivateMessaging.Controls;

public partial class SendMessage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        // Check license


        // Initializes page title control
        //CurrentMaster.Title.TitleText = ResHelper.GetString("messaging.sendmessage");
        //CurrentMaster.Title.TitleImage = GetImageUrl("CMSModules/CMS_Messaging/sendmessage.png");
        //Title = "Send Message"; //ResHelper.GetString("messaging.sendmessage");

        int requestedUserId = 1; // QueryHelper.GetInteger("requestid", 0);
        if (requestedUserId != 0)
        {
            //UserInfo requestedUser = UserInfoProvider.GetFullUserInfo(requestedUserId);
            string fullUserName = null; // HTMLHelper.HTMLEncode(UserInfoProvider.GetFullUserName(Functions.GetFormattedUserName(requestedUser.UserName, true), requestedUser.UserNickName));
            Page.Title = "Sending Message To"; // ResHelper.GetString("messaging.sendmessageto") + " " + fullUserName;
            //CurrentMaster.Title.TitleText = Page.Title;
        }

        // Initilaize new message
        //SendMessage.DefaultRecipient = QueryHelper.GetString("requestid", string.Empty);
        //SendMessage.SendButtonClick += SendButon;
        //SendMessage.CloseButtonClick += CloseButon;
        //SendMessage.SendMessageMode = CMSModules_Messaging_Controls_SendMessage.SendMessageEnum.NewMessage;
        //SendMessage.DisplayCloseButton = true;
        //SendMessage.UsePromptDialog = false;
    }


    private void SendButon(object sender, EventArgs e)
    {
        if (uxSendMessage.ErrorMessage == string.Empty)
        {
            uxSendMessage.SendButton.Enabled = false;
            uxSendMessage.BBEditor.Enabled = false;
            uxSendMessage.SubjectBox.Enabled = false;
            uxSendMessage.FromBox.Enabled = false;
            uxSendMessage.CancelButton.Attributes.Add("onclick", "wopener.location.replace(wopener.location);");
            uxSendMessage.CancelButton.ResourceString = "general.Close";
        }
    }


    private void CloseButon(object sender, EventArgs e)
    {
        // Close
        ScriptHelper.RegisterStartupScript(this, GetType(), "closeSendDialog", ScriptHelper.GetScript("window.close();"));
    }

}
