modelmetadataprovider

I have a ViewModel for which want to be able to set Metadata properties dynamically. For example I would like to be able to customise the DisplayName and validation error messages using the value of other model properties. I plan to do this with a custom MetadataProvider, following Brad Wilson's article . I want the provider only to be used with selected ViewModels. So my question is, how do I configure that? I have seen examples using ModelMetadataProviders.Current = new MyModelMetadataProvider() , but this would presumably use the custom provider for all model classes entities. Is it

I need clarification on how to implement Betty's code solution to transferring data annotation metadata to ViewModels with AutoMapper (see here ). Or if you have a better way, please share that. Maybe the implementation of Betty's answer is obvious to someone who knows AutoMapper well, but I'm new to it. Here is a simple example, what do I add to this code to make Betty's solution work: // Data model Entity public class User1 { [Required] public int Id { get; set; } [Required] [StringLength(60)] public string FirstName { get; set; } [Required] [StringLength(60)] public string LastName { get;

I use AutoMapper to map my domain objects to my view models. I have metadata in my domain layer, that I would like to carry over to the view layer and into ModelMetadata. (This metadata is not UI logic, but provides necessary information to my views). Right now, my solution is to use a separate MetadataProvider (independently of ASP.NET MVC), and use conventions to apply the relevant metadata to the ModelMetadata object via an AssociatedMetadataProvider. The problem with this approach is that I have to test for the same conventions when binding the ModelMetadata from the domain as I do with my
