Many times, we required to upload file with strongly-typed view and also apply validation on uploading file using data annotation validators. In this article, I would like to share, how can we upload a file and validate that file, firstly at client side and after that at server side.
Authorization is the process of determining the rights of an authenticated user for accessing the application's resources. The Asp.Net MVC Framework has a AuthorizeAttribute filter for filtering the authorized user to access a resource.
By default, Asp.Net MVC support session state. Session is used to store data values across requests. Whether you store some data values with in the session or not Asp.Net MVC must manage the session state for all the controllers in your application that is time consuming. Since, session is stored on server side and consumes server memory, hence it also affect your application performance.
The Model-View-Controller (MVC) pattern was introduced in 1970s. It is a software design pattern that splits an application into three main aspects : Model, View and Controller. Moreover, MVC pattern forces a separation of concerns within an application or example, separating data access logic and business logic from the UI.
Caching is a most important aspect of high-performance web application. Caching provides a way of storing frequently accessed data and reusing that data. Practically, this is an effective way for improving web application’s performance.
You can also implement bundling and minification technique with in Asp.net MVC3 and Asp.net 4.0. In previous article Asp.net MVC 4 performance optimization with bundling and minification, I have explained both the techniques, Now I would like to share you could you achieve this functionality with .Net Framework 4.0.
Areas was introduced in Asp.net MVC2 which allow us to organize models, views, and controllers into separate functional sections of the application, such as administration, billing, customer support, and so on. This is very helpful in a large web application, where all the controllers, views, and models have a single set of folders and that become difficult to manage.
In previous articles, I have described the Routing System and how to create Route Constraints in your application. Now the time is to resolve the common error "multiple matching controllers were found" raised by the routing system when your application have more than one controller with the same name in different namespace.
In previous article, I have described the Routing and how to create route in your application. Now the time is how to control the behavior of a route. Basically route constraints is way to put some validation around the defined route.
Basically, Routing is a pattern matching system that monitor the incoming request and figure out what to do with that request. At runtime, Routing engine use the Route table for matching the incoming request's URL pattern against the URL patterns defined in the Route table. You can register one or more URL patterns to the Route table at Application_Start event.
Since registration form is a common form, so I prefer it to demonstrate the basic validation in mvc4. I have already explained the validation with data annotation and how to enable client side validation in mvc razor, now my focus is to develop registration form with client side and server side validations.
Generics provides the type safe code with re-usability like as algorithm. In algorithms such as sorting, searching, comparing etc. you don’t specify what data type(s) the algorithm operates on. The algorithm can be operates with any types of data. In the same way Generics operate, you can provide different data type to Generics.
In the learning phase developer are not much aware of the difference between primitive, FCL (framework class library), reference, and value types. This cause bugs and performance issues into the code. In this article, I would like to expose the different behavior of integer type.
Type Casting is the mechanism to convert one data type to another. While type casting of one data type to another, we get exception if the previous one data type is not compatible with the new data type. To avoid this exception, we have IS and AS operator in C# for safe type casting. Let's understand how to use both of them.
