BC30466: Namespace or type 'UI' for the Imports 'Microsoft.Matrix.Framework.Web.UI' cannot be found.


Ok - story so far. I created a web in a single page in WebMatrix. Then I wanted to compile it, so I spilt it into a codebehind and an aspx and at the same time installed VS.Net 2002 and started working in that.
The app uses an MXDataGrid (well 4 actually), but when run in the browser comes up with :
>BC30466: Namespace or type 'UI' for the Imports 'Microsoft.Matrix.Framework.Web.UI' cannot be found.
I have added a reference to "Microsoft.Matrix.Framework.DLL", and added imports but it still doesnt work SO, I have created a tiny test app, that does nothing expect import and show a text box and it still doesnt work :
Heres the code :

<%@ Page Language="vb" AutoEventWireup="false" Src="WebForm1.aspx.vb" Inherits="WebForm1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<meta name="GENERATOR" content="Microsoft Visual Studio.NET 7.0">
<meta name="CODE_LANGUAGE" content="Visual Basic 7.0">
<meta name="vs_defaultClientScript" content="JavaScript">
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<asp:TextBox id="TextBox1" style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 8px" runat="server"></asp:TextBox>

and the codebehind WebForm1.Aspx.Vb:

Imports Microsoft.Matrix.Framework.Web.UI
Public Class WebForm1
Inherits System.Web.UI.Page
Protected WithEvents TextBox1 As System.Web.UI.WebControls.TextBox
#Region " Web Form Designer Generated Code "
'This call is required by the Web Form Designer.
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
End Sub
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
End Sub
#End Region
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
End Sub
End Class

Thats all. And still I get the BC30466 error. Anyone through any light on this before I pull all my hair out.

Hi there,

Usually that error is received when you change your aspx page without making the corresponding change to your code-behind file. (sometimes people make the mistake of using code-behind, coding in it, editing some aspx pages, and forgetting to re-compile and then browsing to their page and seeing that error). Can you be more specific about what you've done and the pages you have in your project? You say you're working with VS now, so when you say you "spilt" your page into VS, did you copy/paste the code or add an existing item? Did you remember to build your solution before browsing to the page (is it building correctly?)? Is there a dll compiled in your bin directory?

Hi There,

Yup. Basically having writen a single aspx page with both html code and script within Web Matrix, I then got myself a copy of VS 2002 and created a new project.
I split the aspx page into two, and put all the html related stuff in the aspx, and the code in aspx.vb.
I added the relevant imports, @page directives, and built the page, and got the error.
So then I created a brand new project, and made the project thats in the first post. All this does is show a text box and import the matrix framework (although it doesnt use it).
And even with such a small app, I still get the same error.
And now I'm stuck :-(.
