Replace the code in SchoolBL.cs with the following code. You do not need to change anything in the web page to account for this new parameter. You use this ModelMethodContext parameter to call TryUpdateModel or retrieve ModelState. To get around this issue, you must add a ModelMethodContext parameter to any method that accesses TryUpdateModel or ModelState.

When this code is moved to a business logic layer, you no longer have an instance of the Page class to call these members. The Page class contains the TryUpdateModel method and the ModelState property. The most important change to note is that you are no longer executing the code from within an instance of Page class. The methods are almost the same as the methods in the code-behind file, but will include some changes. It will contain all of the data operations that originally resided in code-behind files. In the BLL folder, create a new class named SchoolBL.cs. The methods in this class look similar to the methods you used in the previous tutorials and include the value provider attributes. Now, you will create the class that is called from the web pages.

This tutorial shows how to move all of the code you have written in the previous tutorials into a business logic layer, and then use that code from the pages. You then call the business logic layer from your web pages. To centralize the data interaction code, you can create a business logic layer that contains all of the logic for interacting with data. It can also be very difficult to programmatically test code that resides in code behind files because there is no abstraction layer. This approach works for small sites but it can lead to code repetition and greater difficulty when maintaining a large site. The previous tutorials have shown how to use the code-behind files for data interaction code. Model binding enables you to put your data interaction code in either the code-behind file for a web page or in a separate business logic class. It uses the Visual Studio 2012 template, which is slightly different than the Visual Studio 2013 template shown in this tutorial. The downloadable code works with either Visual Studio 2012 or Visual Studio 2013. You can download the complete project in C# or VB. This tutorial builds on the project created in the earlier parts of the series. You will set the OnCallingDataMethods member to specify that an object other than the current page is used to call the data methods. This tutorial shows how to use model binding with a business logic layer.

This series starts with introductory material and moves to more advanced concepts in later tutorials. Model binding makes data interaction more straight-forward than dealing with data source objects (such as ObjectDataSource or SqlDataSource). This tutorial series demonstrates basic aspects of using model binding with an ASP.NET Web Forms project.
