Model binding not only enables you to specify custom methods to work with your data directly in the data-bound control, but also allows you to map data from the page into parameters from these methods. Web assembly to be able to use them on Web Forms as well.
On the method parameter, you can use value provider attributes to specify the value's data source. NET MVC 4, you will notice the model binding support is similar. In this task, you will update the Grid View to filter its results by the amount of products for each category, receiving the filter parameter with model binding.
I am creating a html file, and writing to it on click of a button.
The button is a html button and i am assigning a server buttons click event to it for doing a postback.

Setting this property will enable you to use a strongly-typed variable to receive the full benefits of the Visual Studio development experience, such as Intelli Sense, member navigation, and compile-time checking.
Write(), response filters, Http Modules, or server trace is enabled.
Validating user input should also be easier with the latest version of Web Forms.
You can use this solution as a guide if you need additional help working through the exercises. Throughout this exercise, you will learn about strongly typed data-controls and model binding.
In this task, you will discover the new strongly-typed bindings available in ASP. One downside with the above approaches is that the calls to Eval() and Bind() are late-bound - meaning you pass strings to represent the property names.
NET portal you can find more examples of the new features in ASP. NET 4.5 and Visual Studio 2012 All sample code and snippets are included in the Web Camps Training Kit, available at https://go.microsoft.com/fwlink/? Installing Code Snippets For convenience, much of the code you will be managing along this lab is available as Visual Studio code snippets.
To install the code snippets run .\Source\Setup\Code file.
