Error Rendering Control - UpdateProgress

Hi i am facing a problem. I created a usercontrol and when i drag it onto my .aspx page, at the design mode of the.aspx page, it shows an Error Rendering Control - UpdateProgress. I have taken a screenshot of the error here:

[My codes on the .aspx page]

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Title="Untitled Page" %>
<%@ Register Src="UserControls/UserInfo/CreateUser.ascx" TagName="CreateUser" TagPrefix="uc1" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <uc1:CreateUser ID="CreateUser1" runat="server" />
</asp:Content>

However the usercontrol itself at design mode, does not give off any error.
