error parsing attribute 'page' & compilation error

AlexW · February 25th, 2011, 12:12 PM

Hi all,

I'm just creating the DarkGrey and Monochrome App_Themes and I'm getting a couple of problems:

1) My error list window is coming up with 4 of the same errors stating:
Error parsing attribute 'page': Cannot create an object of type 'System.Web.UI.Page' from its string representation " for the 'Page' property.

The page declaration is:
<%@ Title="Planet Wrox" Page Language="VB" AutoEventWireup="false" CodeFile="CSSDemo.aspx.vb" Inherits="Demos_CSSDemo" %>

2) After changing the Web.Config file to include:
<pages theme="Monochrome" styleSheetTheme="Monochrome"></pages>

I now get a page error:

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).

It points to line 2:
Line 2: Partial Class MasterPages_FrontEnd
Source File: C:\begASPNET\Site\MasterPages\FrontEnd.master.vb Line: 2

Looks like something is wrong with the page or master page.

Can you post - for both, the @ directive and the Code Behind?

Hi Imar,

Master page directive:
<%@ Master Language="VB" CodeFile="FrontEnd.master.vb" Inherits="MasterPages_FrontEnd" %>

Master Code behind:

Partial Class MasterPages_FrontEnd
Inherits BasePage
End Class

Default page directive:
<%@ Page Title="Planet Wrox" Language="VB" MasterPageFile="~/MasterPages/FrontEnd.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

Default code behind:

Partial Class _Default
Inherits BasePage

End Class

Hi Alex,

Take a look at this:

Code:

 
 
Partial Class MasterPages_FrontEnd
      Inherits BasePage
End Class

Master pages shouldn't inherit your custom base page (which is for Pages only). Change the Inherits line back to MasterPage and it should work again.

Cheers,
Imar

Brilliant, thanks Imar.
