Model Binding and Strongly Typed Views

Model Binding and Strongly Typed Views

Answer by Sharmilli Priyadarsini:

In order to demonstrate model binding, I am making use of the default scaffold for Account registration available when you create a new web application with Visual studio.

Let us see how to create a strongly typed view using the below model,

Now, from your solution explorer, expand the controller folder and open the AccountController.

You will find something like the below action method,

Right clicking near the ActionResult and selecting go to view will navigate you to the Register.cshtml view which is strongly typed with “RegisterViewModel”. In order to make a view strongly typed, you can either do it through api or marking the model on the top of page as shown below:

Doing, so will generate you a strongly typed view as Register.cshtml bound to RegisterViewModel inside the accounts folder in views.

This is how you can create a strongly typed view. Now let us get into the detail of how to design your view by making use of the above model.When you take a close look of the above screenshot, you will see set of html helpers i.e all that follows “@html.” are said to be html helpers. Why because, they will generate the equivalent html to generate your web pages.

Let us take the below example
@html.LabelFor(m=>m.UserName, new{@class=”my-label”})
@ in the above line of code is known as razor syntax. Everything that follows the razor syntax will be rendered at the web server and are C# code in the .cshtml page and vb code in .vbhtml respectively.
html. represents that a html helper so the equivalent output will be a html code generated by the web server. we have different types of helpers like html helper, ajax helper etc.

LabelFor will generate a html label with the name user name which is strongly typed. But usually the label’s will not post the values to controllers they are just plain text. But if we have other controls like textbox, checkbox we can retrive their values in the controller.

Hope this clears your doubt.

I am getting quite confusion in binding the model data in view page, can any one explain me? How exactly it is done?
