I created a page to be the base Page in my web application to add inside it some common functionality. but when I try to inhirite from it then VS gives me the following error:
The type or namespace name 'CentralPage' could not be found(are you missing a using directive or an assembly reference?)
Note: I just want code-behind functionality in the base page.
What should I do ?
I have been trying to find a way to declare two classes using page directive, but it seems like mvc framework doesnt support it.
I have got :
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ContactManager.Models.contact>>" %>
which shows the list of the contacts including edit delete and create option.
What I need to declare another model class which is FileRepository.cs for uploading files on the same page. In this case the page directive should be like:
2. <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ContactManager.Models.FileDescription>>" %>
Is there any way I can incorporate both into one as the first is coming from the database.

I am developing a website which will be having both asp.net pages and MVC pages in it, So I have BaseWebPage class which will be used for both asp.net pages and MVC Views. but My BaseWebPage class is inherited from System.Web.Mvc.ViewPage, So Will there be any code/ functionality break for normal asp.net pages, because System.Web.Mvc.ViewPage is overriding some of the Pagelife cycle methods.

View 1 RepliesI want to extend the System.Web.UI.Page-class with some extra stuff.
In the ctor I need the value of a session-variable.
The problem is that the Session-object is null...
public class ExtendedPage : System.Web.UI.Page {
protected foo;
public ExtendedPage() {
this.foo = (int)HttpContext.Current.Session["foo"]; // NullReferenceException
}
}
If I move the part with the session-object into the Load-Event everything works fine...
public class ExtendedPage : System.Web.UI.Page {
protected foo;
public ExtendedPage() {
this.Load += new EventHandler(ExtendedPage_Load);
}
void ExtendedPage_Load(object sender, EventArgs e) {
this.foo = (int)HttpContext.Current.Session["foo"];
}
}
Why is the Session-object null in the first case??

2) if above is possible then How to access BaseUserControl.ascx code behind file into the ChildUserControl.ascx code behind file?
i have an application consisting of two asp.net projects. And i have have a BasePage which inherits System.Web.UI.Page and have the class some core logic which i require in all of my pages(Implemented in BasePage.cs).

I might be asking a dumb question, but I have a client for whom I need to build many websites (10+) (asp.net 3.5) which will all the pages on each site will have the same codebehind, but the sites will launching in different regions and whilst following the same template, will have different content.I have built and launched site 1, and sites 2, 3 & 4 is nearly live, but it occurs to me that as all the sites are basically the same, the code is going to get more complicated to update as it will be duplicated, so if I need to do a bug fix on one site, I'll need to do the fix on all websites (and this is going to get complicated.)
I was wondering if it possible to somehow create a class library of all the current aspx.cs files, reference this dll in each website and then inherit these classes into the .aspx.cs files. So default.aspx in each site would still have a CodeFile of "Default.aspx.cs", but Default.aspx.cs would inherit the corresponing class from the dll:
using WebPagesClass;
public partial class _Default : WebPagesClass._Default
{ }
The reason for doing it like this is that if I need to change any code on a specific website (for minor changes in languages for instance), I can override the page functions and change the parts required. For all other pages which have not cha, I can just copy from a single website.Is this vaguely possible? If not anyone one got any killer suggestions of how to manage so many websites from a single codebase?

If all my actions have a model that inherits from BaseViewModel, is it possible to initialize this model from the OnActionExecuting method?
Currently in all my actions I do this:
