实施pagedlist MVC后，没有数据返回到视图页面

Question

I am working on displaying data based on the user logged in. In this application, I have added couple of contact information in database. Before, I was able to display all data. Now the thing is I have implemented PagedList in table and while returning data I am not able to return the data of the user who is logged in. All contacts have appeared. Here is my code.

public ActionResult Index(ContactModel contact, string sortOrder, string CurrentSort, int? page)
    {
        var currentUserId = User.Identity.GetUserId();
        contact.UserId = currentUserId;

        int pageSize = 5;
        int pageIndex = 1;
        pageIndex = page.HasValue ? Convert.ToInt32(page) : 1;

        ViewBag.CurrentSort = sortOrder;

        sortOrder = String.IsNullOrEmpty(sortOrder) ? "ContactID" : sortOrder;

        IPagedList<ContactModel> cnt = null;
        switch (sortOrder)
        {
            case "ContactID":
                if (sortOrder.Equals(CurrentSort))
                    cnt = db.Contact.OrderByDescending
                            (m => m.ContactID).ToPagedList(pageIndex, pageSize);
                else
                    cnt = db.Contact.OrderBy
                            (m => m.ContactID).ToPagedList(pageIndex, pageSize);
                break;

            case "Contact_Name":
                if (sortOrder.Equals(CurrentSort))
                    cnt = db.Contact.OrderByDescending
                            (m => m.Name).ToPagedList(pageIndex, pageSize);
                else
                    cnt = db.Contact.OrderBy
                            (m => m.Name).ToPagedList(pageIndex, pageSize);
                break;

            case "Email":
                if (sortOrder.Equals(CurrentSort))
                    cnt = db.Contact.OrderByDescending
                            (m => m.Email).ToPagedList(pageIndex, pageSize);
                else
                    cnt = db.Contact.OrderBy
                            (m => m.Email).ToPagedList(pageIndex, pageSize);
                break;

            case "Default":
                cnt = db.Contact.OrderBy
                        (m => m.ContactID).ToPagedList(pageIndex, pageSize);
                break;
        }
        var contactData = db.Contact.Where(x => x.UserId == currentUserId);
        return View(cnt);

    }

How can I achieve the data of user who logged in with PagedList? Help would be appreciated.

Answer 1

In your code cnt is only ordered list but where clause is applied on contactData . You should apply where on cnt and the return contactData . Like as following

var contactData = cnt.Where(x => x.UserId == currentUserId);
return View(contactData);

This should solve your issue.
