Problem making Role based Menu in MVC application



 I want to make Rolebase menu in MVC such that if user doesnot have permission for some action then that Action name shouldnot be shown in the Menu.

 I have used the code in the url(http://forums.asp.net/t/1566328.aspx) in my MVC application.My application is a Discussion Forum(in MVC) same functionality as in this forum forums.asp.net

 I have used Controllers for post, thread etc.In each controller there are some actions that are using [Authorize(Roles)] attribute

 but this coding does not count  those Actions in Controllers having Authorize attribute according to the url http://forums.asp.net/t/1566328.aspx 

 In the code, Authorize attribute is applied to Controller class, but my requirement is of Applying Authorize attribute to some actions in controller so that some are available for all users and  some links are available rolewise.Now what is the solution for that?



Security: Unify the Role-Based Security Models for Enterprise and Application Domains with .NET


Role-based security allows administrators to assign access permissions to users based on the roles they play rather than on their individual identities. These privileges can be used to control access to objects and methods, and are easier to identify and maintain than user-based security. The .NET Framework provides two role-based security models, which are exposed as two namespaces: System.Enterprise-Services and System.Security.Permissions. Presented here is a comparison of the two options and a discussion of when each is the right choice. The author also demonstrates the process involved in setting up access security and discusses role memberships.

application role how query a view whose reference table is in another db?

Hi everybody. I created  an application role in a database (DB1) and gave it all the rights on a view  in DB1 which refers to a table located in another db (DB2).  I also gave the rights to the app role on a table of  DB1 I tried to use this app. role through the sp_setapprole launched by a user  (server principal?) which is SQL Server administrator (and local administrator (Win 2003 Server)). With the following query SELECT USER_NAME() I see that the approle is being used. Than, if I query the table on DB1 everything works, but if I query the view, referring a table in db2 I get following error:   The server principal "NameOfServerPrincipal" is not able to access the database "DB2" under the current security context. What should I do to make it work? The table in DB2 has the same schema of the view in DB1 which refers to it. I put the DB1 TrustWorthy and both the database have the db_chaining option activated.   Any idea on how to solve the problem would be widely appreciated. Thank you very much. Vania

Client Application Services - Role service cache time out bug

Hi All, For people using Client Application Services with WPF, be aware of this bug. You can configure the "cache time out" for roles to be fetched again from the service. (In the visual studio dialog, Properties -> Services -> Advanced) This means the roles are cached on the client (in a file). If the application asks for roles again, they are not fetched again for "cache time out" time. When you set this value, it goes into your App.config, transformed into seconds. So if you choose 1 minute, the App.config has: cacheTimeout="60".   However, when using the ClientRoleProvider (for instance to do something like clientRoleProvider.GetRolesForUser("SomeUser")), this cacheTimeOut is interpreted in Minutes, not seconds! To prove my point, check ClientRoleProvider.Initialize method:   string temp = config["cacheTimeout"]; if (!string.IsNullOrEmpty(temp)) _CacheTimeout = int.Parse(temp, CultureInfo.InvariantCulture);   Later on, in ClientRoleProvider.GetRolesFromDBUser (what's in a name?), you see: _CacheExpiryDate = cd.RolesCachedDateUtc.AddMinutes(_CacheTimeout);   Testing also shows this behavior. So be aware, and always put the value in minutes in your App.Config!   Regards, Koen

Does the application name property in sql membership provider and role provider has to be the same?



For my FBA authentication I have membership provider application name as 'x' and role provider application name as 'y'.

My FBA login form is authenticating users that belong to application 'x' in aspnetdb database, and not application 'y'.

could anybody help me with this..




Microsoft's Collaborative Application Markup Language (CAML) Loop

discovered an interesting error recently while working with Microsoft's Collaborative Application Markup Language (CAML) that, surprisingly, had received no ink. Partly what surprises me about this is that the error may require you to rewrite large sections of your code if you haven't previously considered this SharePoint limitation. I'll start with some context, but first of all the error is:

Integrating a Legacy Web Application in SharePoint

This month we will continue with the theme of deploying Microsoft's SharePoint as a company intranet by describing a method for integrating a legacy Web application inside a SharePoint site.

In many companies the intranet site is not just a home page with announcements. It houses Web applications used by many different departments. In last month's article, I built a page to search the employee table in Northwind (the sample database included in Microsoft's SQL Server). This month, I will move the Web pages used to add/remove records from the table into the SharePoint intranet.

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.

High-Performance .NET Application Development & Architecture

It has always been a goal of project architects to plan an effective strategy from the ground up in regards to an new application. All relevant factors are taken into consideration with respect to the application, from its design and layout to a functional website infrastructure. Pre-.NET strategies and design guidelines still effective now were developed with Microsoft's DNA (Distributed interNet Application) platform. This model successfully served the purpose of architecting N(any number of)-Tier (levels) applications. In its basic sense, as in most robust, distributed applications, you'll architect 3 main layers or Tiers: presentation, business rules and data access.

Application architecture in asp .net

Application Architecture is the most important process of developing a good application. Some people tends to jump into coding without any architecture laid. Later we see those people changing the architecture and finally the application had to be developed from the scratch with the correct architecture.

In this article I will describe some details about how you can improve the architecture of you application. This article is targeted to the beginner's audience.

Improving Application Performance in .Net

Application performance has always been a concern for Web Application developers. This article contains guidelines and tips for maximizing application performance in ASP.NET.

Logic behind N -Tier Application Development

In the arena of application development, developers all over the world use various programming languages, technical processes, and technical tools. While using number of technical & non technical elements the processes or methods become complex, for simplification of the application development process, developers use various techniques such as dividing the application architecture into layers or parts. In the professional & technical language this separation or division process is called N-Tier Application Development process, where "N" stands for number and "tire" stands for layers or parts.

How to create 3 tier application using LINQ

As you know that in 3 tier architecture there are three layers

User interface layer. (Is our Form in Windows application and .aspx page in Web application)
Data Access layer. (Which provides interface between Business logic layer and Database)
Business Logic layer.(Which stores your application logic)

The article describes Lightbox as, "... a simple, unobtrusive script used to overlay images on the current page." It delivers a nice, professional looking method for displaying images as overlays through the use of hyperlinks.

Solidify Your C# Application Architecture with Design Patterns

design pattern can solve many problems by providing a framework for building an application. Design patterns, which make the design process cleaner and more efficient, are especially well-suited for use in C# development because it is an object-oriented language. Existing design patterns make good templates for your objects, allowing you to build software faster. This article describes several popular design patterns you can use in your own applications, including the singleton, the decorator, the composite, and the state classes, which can improve the extensibility of your applications and the reuse of your objects.

Application Architecture in Windows Forms 2.0

Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.
