Thank you for your help and I apologise for such a long post. I would be interested to hear other people’s thoughts on this. That means ASP.NET MVC Framework uses Data Annotation attributes to implement model validations. scription = scription Īgain, this works, but I just get the feeling the 2nd method is a bit messy or not as efficient at the first way of doing this. ASP.NET MVC Framework provides a concept called Data Annotation which is used for model validation. ViewModelTeam viewModel = new ViewModelTeam() RequiredAttribute: Specifies that a data field value is required. The cheapest way to get from Montevideo Airport (MVD) to Milan Malpensa Airport (MXP) costs only 663, and the quickest way takes just 15½ hours. RegularExpressionAttribute: Specifies that a data field value in ASP.NET Dynamic Data must match the specified regular expression. Data annotation is a process where a human data annotator goes into a raw data set and adds categories, labels, and other contextual elements, so machines can read and act upon the information. RangeAttribute: Specifies the numeric range constraints for the value of a data field. Data annotation is the primary solution that bridges the gap between sample data and AI/machine learning.

Therefore, I changed my ViewModel to look like the following public class ViewModelListItemĪnd I also changed my create Controller to this Specifies that a data field value is a well-formed phone number. Multivalent annotations bring to digital documents of potentially any source format. Now, this works fine, however, the more I read about ViewModels and validation, the more it seems that it is the ViewModel that should be validated, because at the end of the day, it is the ViewModel that is being displayed in the View, not the object. ViewModelTeam viewModel = new ViewModelTeam To validate this View, I have created Data Annotations in a partial class like so Īnd then in my create Controller I have this My View might then have something like this => => => => ) I always return a ViewModel to a View as opposed to passing the actual object as I realise this is poor practice.

I am developing an ASP.Net MVC 3 Web application with Entity Framework 4.1 and I am getting a bit confused with regards using Data Annotations for form validation. In order to use the Data Annotations Model Binder in an ASP.NET MVC application, you first need to add a reference to the .dll assembly and the assembly.
