Ajax.actionlink object route values returning null

问题

I have a view:

@model X.Models.Employee

@Ajax.ActionLink(Model.LastName[lastNameCount - 1].Value1, // <-- Text to display
   "Stuff", // <-- Action Method Name
   new
    {
     //LINE CAUSING ISSUE
      employee = Model
    },
   new AjaxOptions
    {
      bla
    },
   new
    {
     @id = "opener"
    })

and my controller action method looks like this

ActionResult Stuff(Employee employee) {
 //stuff
}

why is my employee returning null? can I not assign the Model to the object route values?

I've tried Model.property and the action method accepts the type associated with that and it works, but not with just Model

回答1:

You using the wrong overload. Employee is a complex object so replace the 3rd parameter

Ajax.ActionLink(...
  Stuff",
  new
  {
    employee = Model
  },
  new AjaxOptions
  ...

with

Ajax.ActionLink(...
  Stuff",
  Model,
  new AjaxOptions
  ...

However Model.LastName[lastNameCount - 1].Value1 suggests property LastName is a collection which wont work (route parameters cannot be created for collections and if you inspect the html you will see something like ...LastName=System.Collections.Generic.List...). In that case you will need to just pass the ID of the employee

Ajax.ActionLink(...
  "Stuff",
  new { ID = Model.ID },
  new AjaxOptions
  ....

public ActionResult Stuff(int ID) {
