Rafeeq on .NET

Revealing Module Pattern makes the code to read better and more structured way, This really useful when we had to repeat the name of the main object when we wanted to call one public method from another or access public variables. This is done by adding a return statement at the end of the function that exposes the public members. The benefits of this approach are. The Revealing Module Pattern allows the syntax of your script to be fairly consistent - it also makes it very clear at the end which of our functions and variables may be accessed publicly, something that is quite useful. In addition, we also able to reveal private functions with more specific names if we wish. The following code demonstrates how the module can be revealed. var myModule = (function () { var name = 'Mohamed Rafeeq'; var age = 28; function updatePerson() { name = 'Mohamed Rafeeq Updated'; } function setPerson() { name = 'Mohamed Rafeeq Set...

Introduction Users are always interested in a rich experience, or a well UI Experience. They expect real-time action between both client and server, no matter if the technology used is HTML5 web sockets or something else. There comes the SignalR. It is framework built on top of ASP.NET and JavaScript library that helps to build rich interactive web applications. We can use signalR in the scenarios where require polling server after fix interval to check if server has something which client needs to update. Well, In Definition   “ SignalR   is an asynchronous signaling framework that helps maintain persistent connections between client and server”. It uses the raw technique of keeping connections open between a web client and a web server. Actually it uses an existing technique called long polling. Behind the scenes, it could very well use Web Sockets transparently. How it works Long Polling: With long-polling, the browser sends a request to the server and ...

I had a scenario where need to localize the data points that are displayed on the chart, that the decimal needs to be localized as comma (,) in Russian and Spanish., Thanks to my friend Gagan for this E.g.: We can assign an EventHandler to FormatNumber Property as Below private MemoryStream RenderGraph() { Chart barchart = new Chart (); //many number codes are removed //Removed other formatting lines barchart.FormatNumber += new EventHandler < FormatNumberEventArgs >(ConvertChartDecimalFormat);             barchart.DataSource = dt;    barchart.Series[0].XValueMember = "XProp" ;             barchart.Series[0].YValueMembers = "YProp" ;             barchart.DataBind(); //return the memory stream image } Followed the event method will look as below.  vo...

Knockout is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model. Any time you have sections of UI that update dynamically (e.g., changing depending on the user’s actions or when an external data source changes), KO can help you implement it more simply and maintainably.

I had the same issue, (Error: ko.mapping.updateFromJS, use ko.mapping.fromJS instead) I bugged for long time, then i tried the another alternative. fromJS  the functionality is the same, but be aware that updateFromJS's parameter list is just the other away around, so instead of doing:    ko.mapping.updateFromJS( viewModel, jsData); You need to replace this with:    ko.mapping.fromJS( jsData, {}, viewModel );

Observer Pattern "The Observer Pattern Defines a one-to-many dependency between objects so that when one object changes state, all of its dependents are notified and updated automatically." Publishers + Subscribers = Observer Pattern C# Introduced , IObserver<T> and IObservable<T> which will help push-based notification,also known as the observer design pattern. The IObservable<T> interface represents the class that sends notifications (the provider); the IObserver<T> interface represents the class that receives them (the observer). T represents the class that provides the notification information. An IObserver<T> implementation arranges to receive notifications from a provider (an IObservable<T> implementation) by passing an instance of itself to the provider's IObservable<T>.Subscribe method. This method returns an IDisposable object that can be used to unsubscribe the observer before the provider finishes sending...
