handles the app's details presentation and consumer conversation. A view is surely an HTML template with embedded Razor markup. Razor markup is code that interacts with HTML markup to produce a webpage that is despatched for the shopper.

Building the view model the single source of information for your view drastically enhances its ability and price for unit screening.

undertaking it while in the controller no less than can make it testable (While not accurately like the above mentioned - you most likely desire to just take an ISerializer being a dependency in order to mock it)

Although a ViewModel consists of several entities, at its Main a ViewModel remains to be just a category – and one which doesn’t even inherit from just about anything Unique, as several MVC courses do. Physically, ViewModels can exist in different places, detailed under:

Although doing this we are going to focus on two approaches which might be used to go details from controllers to views: ViewData and ViewModel.

So very first, make a folder at the root Listing of one's application With all the identify ViewModels, then create a class file While using the title StudentDetailsViewModel.

Essentially the most robust method is always to specify a model type in the view. This model is usually referred to as a viewmodel

View Model is a class that we are able to use for rendering information on View. Suppose you've two entities Area and PlaceCategory and you wish to accessibility information from both entities using only one model then we view model in asp.net mvc use ViewModel.

community course Tackle community string Title get; established; community string Road get; established; community string Town get; established; general public string Point out get; established; general public string PostalCode get; established;

ViewModels would make the application safer while you don't have to expose the doubtless hazardous Houses like UserRole, isAdmin in the ViewModel
