In this way, ViewModel aids us to organize and handle details within a strongly typed view in a far more flexible way than intricate objects like models or ViewBag/ViewData objects.

You shouldn't utilize the domain (enterprise) entities within your view model. If you do, a view model is pretty useless as it stills contains organization logic which you won't want within the view. The model with your illustration would not truly depict a true-globe circumstance, a view model is not likely necessary for it anyway.

Andrew experienced a terrific response but I planned to tweek it just a little. The way this differs is I like my ModelViews not to have overhead knowledge in them.

While undertaking this we are going to talk about two techniques that can be used to move details from controllers to views: ViewData and ViewModel.

Why is R² not equivalent to the sq. of Pearson's correlation coefficient (r²) in my multivariate regression model?

The Html.DropDownList() helper strategy previously mentioned will take two parameters. The initial will be the identify with the HTML kind component to output. The 2nd would be the "SelectList" model we passed by using the ViewData dictionary. We're using the C# "as" key word to cast the sort inside the dictionary as a SelectList.

The application is easier to keep up because it's superior organized. Views are commonly grouped by app attribute. This can make it easier to come across associated views when focusing on a feature.

– Berryl Commented Oct 31, 2010 at three:33 I have observed lots a lot more, currently, that the ViewModel is being used in Asp.Internet MVC. it would appear that the ViewModel has far view model in asp.net mvc more business currently being in the view as opposed to Area Model. And so the pattern that we've been employing is to possess the domain models assemble the most important aspects of the ViewModel.

Together with improved coding methods, there are many organization reasons demonstrating why you could possibly think about using ViewModels:

While in the olden days of Website improvement, developers applied RecordSet objects or maybe more not too long ago DataSets or DataTables as a way to transfer details in the databases to a view template. The View template might have been a basic ASP file that contains a mixture of HTML and server-aspect code, or an internet Kind consisting of databound server controls just like a GridView or ListView. Irrespective, the information is untyped and working with it usually includes referring to things by index or through the use of "magic strings" to reference facts container values that borrow with the schema with the databases that the information originated from.

The Model retrieved from the databases needs to be mapped towards the ViewModel. You may take aid in the equipment like AutoMapper To do that work.
