Four Main Principles
Stateful Event-Driven WindowsForms/WPF-like Client-Side UI
When Microsoft introduced ASP.NET it looked great because it tried to mimic the rich client stateful development model by saving the state between the requests in the ViewState and triggering events on the postback. But while it looked very much as the rich
client model it didn't truly behave like one, and that's why the MVC was suggested as better, more web-friendly model thanks to the fact that it doesn't try to hide the stateless nature of the web. But despite the growing popularity of MVC frameworks,
MVC is neither convenient nor natural pattern for building fully-blown reach UI, and good alignment with HTTP seem to be the only real, yet significant, benefit.
In the same time, improving capabilities of the modern browsers, client-side scripting languages and libraries are now allowing moving the UI logic completely to the client, reserving server calls only to obtain the data. This makes it possible to return to
the truly stateful, event-driven development model.
Declarative UI Model
Separating the UI model has proven to be of the great convenience for a developer and contributes largely to a success of the technologies like WPF, and products like MS Dynamics AX. While idea of splitting the work between UI designer and developer in reality
never worked, having separate model makes it possible to build UI with aid of visual form designers, which simplifies a life of developer. What is more important, it standardizes the whole process by defining the limited set of available building blocks (textbox,
gridview) with the pre-defined and unified behavior. For the same reason styles and themes can also be applied consistently and with much less effort.
Since the whole UI is now created declaratively, the certain mechanism is required to fill the controls generated in runtime to the data retrieved from server. This mechanism is known as databinding.
The result of the UI generation from the declarative model should be predictable, transparent and customizable. All this is achieved by the use of HTML-templates. Every control type allowed in the UI model is mapped to the HTML template, which parameters are
replaced with the values from the model at the time of the UI generation. This allows customizing process of HTML rendering, take full advantage of CSS to style the UI, and achieve more clarity in general.
