Custom Control Parser Error9/3/2003 10:15:05 AM

0/0

Hi,

I'm getting the following error after having created a custom control and trying to run it off a web page.

Parser Error Message: Could not load type AESWebAccess.Login.SimpleText from assembly AESWEBACCESS, Version=1.0.1341.7455, Culture=neutral, PublicKeyToken=null.

Source Error:


Line 21: <br>
Line 22: Enter your name:
Line 23: <Custom:SimpleText Text=" " OnChanged="Text_Changed" id="Box" runat="server" />
Line 24: <br>
Line 25: <br>


Source File: C:\inetpub\wwwroot\AES NET PROJECTS\AESWEBACCESS\TestStuffHere.aspx Line: 23


--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.573; ASP.NET Version:1.1.4322.573



Any ideas what causes this error? I haven't been able to run even very simple custom controls. I'm using visual Studio .net 2002. I did upgrade to .net 1.1 framework. Is there some compatibility issue?

Thanks for the help.

This could be caused by a couple of things. First make sure you have a namespace declared for that assembly via a page declaration at the top of your web form. You will then use whatever TagPrefix you specify to access the controls of that assembly. Here is an example:

<@ register tagprefix="myPrefix" namespace="AssemblyNamespace" Assembly="MyAssembly.MyControls">

The other issue maybe that if you already have this declared in your web form, the assembly it's referencing is either not in the GAC of the machine attempting to load the assembly or the assembly isn't in the bin direcotry of your web app.

Thanks for the reply. I think I have done all that you suggested. I still have the error. The same error appears on my laptop which runs version 1.0 of .net framework.

Here are some more details of what I have:


The .aspx file contains the following @ Register directive:

<%@ Register TagPrefix="Custom" Namespace="AESWebAccess.Login" Assembly = "AESWEBACCESS" %>


SimpleText.vb contains the following declaration:

Namespace AESWebAccess.Login

Public Class SimpleText
Inherits Control
Implements IPostBackDataHandler


The name of the assembly in the bin directory is AESWEBACCESS.dll. Visual Studio .net created it for the whole application when I built the solution.

Any ideas?

Here is some more info, still haven't figured it out.

When I use the command line compiler and then move the .dll to the bin directory, the custom control works fine-Any of them.

But whenever I compile it in the Visual Studio .Net assembly it gives me the above error. Am I missing something somewhere? Do I need to add anything to the Code Behind file? I can't find anything anywhere in documentation or online to help me figure out what causes this problem.

Thanks for the help.

What does the directory structure of your app look like. A common issue is attempting to use assemblies that are in different logical applications. This would come into play if you have say an application at:

http://somewhere.com/myApplication

and then a second application under that:

http://somewhere.com/myApplication/mySecondApp

The issue comes into play if both are virtual directories or represented in the CLR as seperate AppDomains. A reference to an assembly cannot be made for an assembly in another application.

Thanks for the suggestion.

I've looked at that as well. It's the only application running in that virtual directory. I've created new applications with VS.net and it won't work then either. The only time I can get it to work is if I manually compile the custom control. I've even deleted the .dll that VS.net creates in the bin directory and recompiled the app. It never works.

I've even deleted the temporary files from the shadow copy directories. Still no luck.
This is EXTREEEEMLY frustrating.
