This project is currently a proof of concept in building a MVP abstraction layer for ASP.Net WebForms. By applying a MVP framework onto ASP.Net, developers can write more decoupled code than the traditional codebehind model which increases the maintainability and testability of the code.

For those who may not be familiar with the Model-View-Presenter (MVP) design pattern, MVP provides a way of structuring your code into specific responsibilities similar to the Model-View-Controller (MVC) pattern. Unlike MVC though, MVP distributes the repsonibilities a little bit differently in order to focus more on its use for developer user interfaces.

####Model The Model is simply a data construct used to describe the data to display and be manipulated by the user interface. This is very similar to the concept of a View Model or or Data Transfer Object (DTO).

####View The View is a template used to display the data represented in the Model object in addition to routing events (e.g. button clicks) to the Presenter so such can be acted upon.

####Presenter The Presenter is used to retrieve Model data from the data stores or repositories and formats it to display in the appropriate View.

Simplify takes these concepts of the MVP design pattern and attempts to merge them with some of the constructs imposed by the ASP.Net WebForm framework.

####Page Routing ASP.Net Webforms uses a page-based routing system (by default) where users browse to a specific resource in their and that page's code behind file invodes various server-side methods that correspond to it's own page life cycle.

With Simplify, the routing aspects of ASP.Net WebForms remains intact; however, the Page_Load event shifts responsibiltiy to the HandleRequest method of the Presenter object associated with the Page.

####Models Models in Simplify are of type dynamic. Models are set by the Presenter and are used by the View in a similar manner of the ASP.Net MVC framework.

####Views Views in Simplify are slightly different from ASP.Net WebForms. The same naming conventions and server tags still exist; however, Views in Simplify do not have a Code Behind file. With Simplify, logic should be sent to the Presenter object that can be associated with the View. To bind a Presenter to a View in Simplify, the Page directive at the top of each page needs to change to something similar to the following:

<%@Page Language="C#" Inherits="Simplify.BasePage<Simplify.Contacts.ReadPresenter>" %>

In the above example, the View inherits from a Simplify BasePage generic class that takes an instance of an IPresenter class to bind the logic between the two components.

In addition to how a View is associated with a Presenter, Views can also tap into the Model object which the Presenter creates to send data to the View. All Views can access their Model in a manner similar to other following:

<div>
    <label for="FirstName">First Name</label><br />
    <span><%=this.Model.FirstName %></span>
</div>

<div>
    <label for="LastName">Last Name</label><br />
    <span><%=this.Model.LastName %></span>
</div>

Lastly, you'll have to update the PageParserFilter for the web pages. Thankfully, this can easily be done via the web.config

<system.web>
    <compilation debug="true"/>
    <pages pageParserFilterType="Simplify.SimplifyPageParserFilter, Simplify, Version=0.0.1.0, Culture=neutral"/>
</system.web>

####Presenter Coming Soon.
