Web Forms :: Get A List Of All Classes That Inherit From BasePage In The Web Application?
May 13, 2010
I need to get a list of all of these webforms.
As the subject reads, how can i accomplish this ? All my webforms inherits from a class called "BasePage". It can also suffice with only getting a list of all the webforms in the application, regardless of base class since i can check inheritance later in code.
Reason i'm asking is because i'm building my menu and i'm implementing security enforced user visibility based on what pages there are in the webbapplication, and what roles each page demands, and display these to the user in the menu.
Using sitemaps are insufficient, i need to provide much more info for all the pages i have on my system.
Using this technique i can query my "PageProvider" for like:
GetAllPagesVisibibleToUser(MembershipUser user)
DoesUserHaveAccessToPage(MembershipUser user, BasePage forPage)
I'm also planning on implementing this technique on WebUserControls.

I have a MasterPage project which is a class library project (it includes themes, style sheets, menus etc) and all applications use them.
I am using the BasePage concept for dynamically adding title,meta tags and descriptions. This BasePage Class inherits system.UI.Page and the aspx pages in the project inherits the BasePage class.
Now i need to move this BasePage class from my application to the Master Page Project so that all the projects/applications can reuse the same code.
I tried add the basepage.cs in the App_code folder and tried calling it in the page directive like below
<%@
Page
Language="C#"
MasterPageFile="~/Master/Layout/MasterPage.master"
AutoEventWireup="true"
CodeBehind="xxxx.aspx.cs"
CodeFile="xxxx.aspx.cs"
Inherits="xxxx"
ValidateRequest="false"
EnableEventValidation="false"
ViewStateEncryptionMode="Never"
CodeFileBaseClass="~/Master/App_Code/BasePage<Page>"
Title="Title"
Meta_Keywords="xxxx,yyyy,zzzz"
Meta_Description="This is a test" %>
But i am getting error
Could not load type '~/Master/App_Code/BasePage<Page>'.
This was working fine till the BasePage class was inside the application. But once i moved it out of the project and added it to the master page project i getting this error.

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 converted a ASP.Net website to ASP.Net web app and changed the framework from 2.0 to 3.5
The web application works fine in Visual studio. However, If I compile the app in a dll, and try to reuse its middle layer in another web project, All the classes that have a static variable crash. Code like:
public static string myString = "Something";
However if I convert it to a property like this:
`public static string myString {get{return "Something";}}`

We are trying to use a BasePage class (which inherits from Page) to populate and set the Meta Keywords and Meta Description Tags. I am using masterpages and below is an example code extract... According to examples on the internet, I could then set this also via the Page Directive using the MetaKeywords and MetaDescription properties, but they do not appear.
I have tried setting the CodeFileBaseClass="MyNamespace.UI.BasePage" but this does not work either. Using debug I can see that the BasePage classes' MetaKeywords and MetaDescription properties are not being set within my content page. I can access the properties but not set them.

I have a standard .aspx page that inherits from the base page like so
public partial class myinterviews : BasePage
I have a standalone .ascx page, it has a grid and a datasource. This .ascx page is apart of the .aspx page that inherits from the base page. How can I reference the methods, properties from the base page from within my .ascx page?

I have a large asp.net project to which I want to add MVC functionality. I have added the necessary references into the project (System.Web.Mvc (v 2.0), System.Web.Abstractions (v 3.5) and System.Web.Routing (v 3.5) and amended all the required files (Global.asax (routing requirements), the web.config, project (Controllers and View folders) and created a basic HomeController and ViewPage.
When I run the application and attempt to go to the controller via {serverpath}Home I am getting the error "An unhandled exception has occurred - Could not load file or assembly 'System.Web' or one of its dependencies. The system cannot find the file specified." I've tried browsing the net but the error is too vague; is there a good way to identify exactly why the assembly cannot load?

We are using nested master page the master page is seperate class library project and all the other projects refer to them. We wanted to have a basepage class which load title, meta tags and keywords dynamically. It was working fine till it was inside the main project. We wanted the basepage class to be more generic and to have it reside in a single place. So i tried created a seperate class library project but i getting error "Could not load type" ..
How to have the basepage class outside the project?

I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?

I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).

I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.

I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?

I'm new to programming in ASP.NET, but I'm making my way through Wrox's Beginning ASP.NET 3.5 in C# and VB.NET.
I'm at a section where I'm creating a BasePage. I successfully created a BasePage by creating a new class file in my App_Code folder called BasePage.cs with the following code:
[Code]....
If I run that code everything works out fine. The page loads and all is well. But, if I try to do the same thing to a page that uses my MasterPage.master file, I get the following error:
Object reference not set to an instance of an object.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Why is that? In the example code from the book (that also uses a MasterPage.master file), everything excutes and runs just fine. But in my test, I get the above error. I've tried comparing my pages to the books included source pages, but I can't find any differences.

I want to set useraccess permission for webforms. I want to have a common class say userClass for that function where privileges are set for e.g. (canAdd,canDelete,canEdit etc). From the webform I need only to check the properties such as canAdd, canDelete, canEdit are true or false. According to that privileges are set.
I dont want to call the userClass function on every page load. It should be automatically called when the page gets loaded.
