Question

I’m using NHibernate and I’ve got a Campaign class and it has a Client class as one of its members and I’m attempting to use ModelState.IsValid in my [HttpPost] public Create (CreateCampaignViewModel vm) method.

As my ViewModel contains the object Campaign ModelStats.IsValid is always false as I’m passing the Client.Id from the form instead of the entire Client object.

Is there a way to have it load the Client member before it runs the validation code that sets ModelState.IsValid? Or is there a way to refresh the state of ModelState after I ‘manually’ retrieve the client object based on the ClientId and bind it to the Campaign?

You probably want to add an attribute to the parameter of your action method, to disable binding of the Id:

[HttpPost]
public Create([Bind(Ignore="ClientId")]CreateCampaignViewModel vm)
