JustCode Error: asp:TextBox not registered

[Eric]

I have a ASP.net WebForms project where I am getting errors regarding common toolbox items not being registered. Any help in addressing these errors would be most appreciated as my project has 110 files and is reporting over 4000 errors and most seem be in this category so it is making it hard to know what are actual errors vs these odd reports. Thanks!

JustCode version Q1 2014 (2014.1.225.1)

The errors that are reported from JustCode from the snippet below are: 
ASP.Net tags: ASP.net tag asp:Content not registered
ASP.Net tags: ASP.net tag asp:Content not registered
ASP.Net tags: ASP.net tag asp:Literal not registered
ASP.Net tags: ASP.net tag asp:Content not registered

<% Page Title="" Language="C#" MasterPageFile="~/MasterPages/MasterPage_3ContentPanel.master" AutoEventWireup="true" CodeFile="Registration.aspx.cs" Inherits="Account_Registration" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<asp:Content ID="Content1" ContentPlaceHolderID="BannerLogoContentPlaceHolder" Runat="Server">
         <script type="text/javascript">

             function openRadWin() { $find("<%=termsAndConditionsWindow.ClientID %>").show(); }
     </script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="PageNameContentPlaceHolder" Runat="Server">
    <asp:Literal ID="pageTitleLabel" runat="server"></asp:Literal>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="PageBody" Runat="Server">
</asp:Content>

Hi,

Thank you for your feedback.
I reviewed it and tried to reproduce your issue, but was not able to. Could I ask you to try refreshing the code analysis from "JustCode -> Analysis -> Refresh Code Analysis". If the errors are still there after the refresh, could you send us a sample solution reproducing your issue?
It will help us find and fix it as soon as possible.
Your help is highly appreciated!

Regards,
Ivan
