When doing Update/Create/Destory operations, two operations get posted to the controller:

First Create operation then a Destroy/Update/Create.

And the ModelState is invalid always.

I have code:

Client side grid:

public ActionResult Read([DataSourceRequest] DataSourceRequest request)
{
var users = db.Users.Select<DAL.User, UserViewModel>(u => new UserViewModel
{
ID = u.ID,
FirstName = u.FirstName,
LastName = u.LastName,
Email = u.Email,
Password = u.Password
});

return this.Json(users.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit([DataSourceRequest] DataSourceRequest request, UserViewModel user)
{
if (user != null && ModelState.IsValid)
{
var userToUpdate = db.Users.FirstOrDefault<DAL.User>(u => u.ID == user.ID);
if (userToUpdate != null)
{
userToUpdate.FirstName = user.FirstName;
userToUpdate.LastName = user.LastName;
userToUpdate.Email = user.Email;
userToUpdate.Password = user.Password;

db.SaveChanges();
}
}

return Json(new[] { user }.ToDataSourceResult(request, ModelState));
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create([DataSourceRequest] DataSourceRequest request, UserViewModel user)
{
if (user != null && ModelState.IsValid)
{
var userToCreate = new DAL.User();
userToCreate.FirstName = user.FirstName;
userToCreate.LastName = user.LastName;
userToCreate.Email = user.Email;
userToCreate.Password = user.Password;
db.Users.Add(userToCreate);

db.SaveChanges();
}

return Json(new[] { user }.ToDataSourceResult(request, ModelState));
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Destroy([DataSourceRequest] DataSourceRequest request, UserViewModel user)
{
if (user != null && ModelState.IsValid)
{
var userToDelete = db.Users.FirstOrDefault<DAL.User>(u => u.ID == user.ID);
if (userToDelete != null)
db.Users.Remove(userToDelete);

db.SaveChanges();
}

return Json(new[] { user }.ToDataSourceResult(request, ModelState));
}

// GET: Users
public ActionResult Index()
{
return View();
}

Something seems to be wrong with:

destroy: {
url: crudServiceBaseUrl + "/Users/Destroy",
type: "POST",
dataType: "json"
},

parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}

and the receiving function:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Destroy([DataSourceRequest] DataSourceRequest request, UserViewModel user)

The data is there in the parameterMap function but it's empty when it's received in the controller.
