Question

Given the following class, what is your opinion on the best way to handle create/edit where Attributes.Count can be any number.

public class Product {   public int Id {get;set;}   public string Name {get;set;}   public IList<Attribute> Attributes {get;set;} }  public class Attribute {   public string Name {get;set;}   public string Value {get;set;} } 

The user should be able to edit both the Product details (Name) and Attribute details (Name/Value) in the same view, including adding and deleting new attributes.

Handling changes in the model is easy, what’s the best way to handle the UI and ActionMethod side of things?

Answer 1

Use the FormCollection and iterate through the key/value pairs. Presumably you can use a naming scheme that will allow you to determine which key/value pairs belong to your attribute set.

[AcceptVerbs( HttpVerb.POST )] public ActionResult Whatever( FormCollection form ) {  .... }
