Web Notes

Today I want to cover a very common scenario about how to create a HTTP client for a WebAPI 2 service. To present my implementation I will be using one of a Task<T> extension method that I described recently on my blog. Let`s start from defining an API service. In this example it udes a REST based WebApi service with the following implementation.   [ AllowAnonymous ]     public   class   CityController    {         ///   <summary>         ///  The city repository.         ///   </summary>         private   readonly   ICityRepository  cityRepository;         ///   <summary>         ///  Initializes a new instance of the  ...

Introduction to MVC In the last few years a software architecture changed very heavily. From desktop (forms) application which were very popular in Windows XP users move to SOA and now completely start using web based solution hosting in a cloud . Of course such evolution is not something bad, just the opposite in my opinion because web based application are highly scalable, better secured and available from each place in the Earth where user has an Internet connection. Such a big changes in software architecture cause that also programming model has to change. As response for this need, IT companies start working for on new technologies and improving existing ones. APIs became very popular tool  in a developer hands and whole communication became much more lightweight (by switching from XML to JSON) - mainly because the emerging market of mobile devices. In a new MVC version 4 also Microsoft introduce some improvements which allow developers creating web service...

Almost in each modern website project one of the feature is suggesting user possible items to select when he start typing one of them. Such functionality is done by using control named autocomplete . Under the hood  it consists of at least three elements: UI control which allow user to type some text - mainly this in HTML input of text type Server-side function which serves data to be auto-completed Client-side logic (written in JavaScript) which , by using AJAX, send request to the server asynchronously and then process the results. When we think about creating autocomplete control in ASP.NET MVC 4 we definitely should take a look at  jQueryUI framework. One of the feature of this framework is autocomplete control which enables users to quickly find and select from a pre-populated list of values as they type, leveraging searching and filtering. That sounds very good and is excellently what we are looking for. ...
