Parser Error Message: Could not load type

[OuTCasT]

Ive created a new page in my website project.
Now I have used a master page as follows

<%@ Page MasterPageFile="[ProjectName].master" %>

To use codebehind i have added this to the string

<%@ Page MasterPageFile="[ProjectName].master" CodeBehind="registerbusiness.aspx.vb" Inherits="[ProjectName].registerbusiness" %>

When i run the project i get this error:

Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Could not load type '[ProjectName].registerbusiness'.

Could you inform me why I would be getting this error.

Just so you know, what you have as [ProjectName] is actually the Project's Namespace. By default the namespace for the project is the same name as the project; however this can be changed, so the ProjectName does not always match the Project's Namespace.

Anyways, your @Page directive should look something like:

<%@ Page MasterPageFile="[relative path to the master page]"
                  CodeBehind="registerbusiness.aspx.vb"
                  Inherits="[ProjectNamespace].registerbusiness"
                  Language="vb"
%>

When you look at code implementation found in your registerbusiness.aspx.vb you should see the a Partial Class with the same name as specified in your @Page directive's Inherit attribute. If this name is different then it won't work. If the partial class is in a different namespace, then it won't work either.

Here's an example of the @Page directive for a page that uses a MasterPage (located in the root of the project) from my project:

<%@ Page MasterPageFile="~/MasterPage.master"
                  CodeBehind="Default.aspx.vb"
                  Inherits="TestProject.Default"
                  Language="vb"
%>

And the VB.NET code in the Default.aspx.vb file looks like:

Partial Public Class Default
    Inherits System.Web.UI.Page
'......
'......
End Class

The default namespace (for the project) is automatically applied to the Default partial class.

Here is my masters page

<%@ Master Language="VB" AutoEventWireup="false" CodeBehind="CreativeHearts.master.vb" Inherits="Creative_Hearts_2._0.CreativeHearts" %>

And here is my code for my RegisterBusinessLogin.aspx page

<%@ Page MasterPageFile="Creativehearts.master" CodeBehind="registerbusinessLogin.aspx.vb" Inherits="Creative_Hearts_2._0.registerbusinesslogin" %>

It sounds like you haven't done a lot of work on the page that's using the master page yet.

Try adding a new page that uses master the master page:

• Right click on the solution in the solution browser
• Click on Add -> New Item
• Choose Web Content Form and give it a name
• Click the Add button
• Click the Master Page that you want the new web/content form use
• And click OK

This will give you a page that should work properly.

I think that somewhere along the line i accidently renamed the project and then renamed it back again. Because when I add a fresh webform and i dont reference my master page then i get the same error message.

I just redone the project.

Oh this is a website not a web application.
Try removing the Namespace from the page directive...see if that helps?
