Hi,

 After I migrate from from ASP.NET 1.0 to 2.0, I get this error mesage in all the code behind file where inherit this file "InheritPage"

Code Behind:
Public MustInherit Class AssignUserGroup
Inherits InheritPage  <--- Error Message : Type 'Inherit Page' is not defined.

In fact, it is  all of the code-behind file is references to this file. So, with all the aspx file header contain the below code also get error

<%@ Reference Page="~/commonpage/inheritpage.aspx" %>  <--- Error Message : 'Context' is not member of 'xxx'

I have refer to this website http://msdn2.microsoft.com/en-us/library/aa479312.aspx , known this should be the "Circular Reference Issue", but i cannot solve the problem. Anyone could give the solution will be very appreciate!!

try chaning your code to:

Public MustInherit Class AssignUserGroup
                                   Inherits CommonPage_InheritPage 

Visual Studio prefixes the page class name with the folder name. If you have a look in the code behind for commonpage/inheritpage.aspx see what the actual name of the class is.

let me know if this solves your problem.

Hi, 

You can upload the image to an image hosting server and add the link here.

REPLY FROM SCOTT:

If you just want to inherit some functionality you could create a BaseCommonPage that inherits from System.Web.UI.Page and store it in the App_Code folder. This would then be available to all other pages that inherit from it.

App_Code/CommonBasePage.vb:

End Class

Then you web pages could inherit from it:

                  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
                            Response.Write(MyBase.myMethod)
                  End Sub
End Class

Thank you very much to Scott

There is a good article by Scott Mitchell on this http://aspnet.4guysfromrolla.com/articles/041305-1.aspx. It may be of some use.
