At my job, I get the opportunity to talk to many .NET developers who want to learn Angular. Often, I’ve seen that they bring their .NET skills and work to map that in the learning of Angular. While the effort and drive to learn is there Angular is not .NET.

Since Angular is a pure JavaScript library, I’ll simplify basic but important concepts of Angular to .NET developers in this post series.  In this article, we’ll learn about Data Bindings in Angular. Luckily, Data Binding in Angular is much simpler than in .NET.

First, Let’s revise some of data binding techniques in .NET. For example, in ASP.NET MVC, you do data binding using a model. View is bound

1. To an object
2. To a complex object
3. To a collection of objects

Essentially, in ASP.NET MVC, you do data binding to a model class. On the other hand, in WPF, you have data binding modes available. You can set the mode of data binding in XAML, as follows:

1. One-way data binding
2. Two-way data binding
3. One-time data binding
4. One-way to source data binding

If you are following MVVM patterns, then you might be using INotifyPropertyChanged interface to achieve two-way data binding. Therefore, there are many ways data bindings are achieved in world of .NET.

Data binding in Angular, however,  is much simpler.

If you are extremely new in Angular, then let me introduce you to Components. In Angular applications, what you see in the browser (or elsewhere) is a component. A component  consists of the following parts:

1. A TypeScript class called Component class
2. A HTML file called Template of the component
3. An optional CSS file for the styling of the component
