Excuse me,


In Chapter 5,Roles¡¢EditRole¡¢RoleAssignments in admin is error.It is about

(SitePrincipal)Context.User.Moreover£¬what mean about"Put user code to initialize the page

here"in the progam(EditRole.aspx.cs)?

I tried to complete thePhile\Modules\admin\roles.aspx ,but received the following message

It's likely to the class SitePrincipal and class SiteIdentity can not work.

What are some possible solutions that I need to check?

Thank you for your help!!

Hello, excuse for my English. I see that nobody has not answered you. Also I have the same problem I have resolved the problem? I continue to try. If I resolve I make you to know. Soon...

Could you post the code? I don't have the book. It's likely that you are storing a custom SitePrincipal object in the context's User property. However, after the page reloads, it drops that reference. Use another mechanism, such as the Session, to store that reference.

This sounds like the problem that we answer about once every 2 weeks. The order of these 2 lines has to be switched:

#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
 base.OnInit(e); // THIS LINE MUST COME FIRST !!!!
 InitializeComponent();
}
