Compound View Model object causing remote validation failure

Question

I have used a pattern of compound view models for a few of the forms in this project. It works very well.

In this case I have a VendorAddress view model. I use Add

Answer 1

Try specifying a prefix to help the model binder correctly bind the Address.PostalCode and Address.State request values to their corresponding action parameters:

public ActionResult CheckState(
    [Bind(Prefix = "Address.State")]string State, 
    [Bind(Prefix = "Address.PostalCode")]string PostalCode
)
{
    ...
}
