Answer 1

I will explain the way to implement pagination in asp.net mvc.

ProductController.cs

private ProductContext db = new ProductContext ();

public ActionResult Index()
{
    string pageString = "";
    try
    {
        pageString = Request.Url.Segments[3];
    }
    catch (Exception)
    {
        pageString = null;
    }

    int page = (String.IsNullOrEmpty(pageString)) ? 1 : Int32.Parse(pageString);
    Product userModel = new Product();
    int totalProducts = userModel.GetTotalProducts();

    PaginationFunction pagination = new PaginationFunction(true);
    pagination.BaseUrl = "/Product/Index/";
    pagination.TotalRows = totalProducts;
    pagination.CurPage = page;
    pagination.PerPage = 5;
    pagination.PrevLink = "Prev";
    pagination.NextLink = "Next";
    string pageLinks = pagination.GetPageLinks();
    int start = (page - 1) * pagination.PerPage;
    int offset = pagination.PerPage;

    List products = userModel.GetProducts(start, offset);

    ViewData["title"] = "Pagination in Asp.Net Mvc";
    ViewData["totalProducts"] = totalProducts;
    ViewData["products"] = products;
    ViewData["pageLinks"] = pageLinks;

    return View(db.Products.ToList());
}

ProductModel.cs

public class Product
    {
        private ProductContext db = new ProductContext ();

        public int GetTotalProducts()
        {
            return db.Products.Count();
        }

        public List GetProducts()
        {
            return db.Products.ToList();
        }
        public List GetProducts(int start, int offset)
        {
            IEnumerable query = from m in db.Products
                                       orderby m.Id descending
                                       select m;
            query = query.Skip(start).Take(offset);
            return query.ToList();
        }

    }

Index.aspx

    
View Users
    

    <%: Html.ActionLink("Create New", "Create") %>
    
    
Total Users: <%= ViewData["totalProducts"] %>

    <% if ((int)ViewData["totalProducts"] == 0)
       { %>
        
Sorry! No Users Found.
    <% }
       else
       { %>    
    

        <% foreach (Product u in (List)ViewData["products"]) 
           { %>        
             
        <% } %>
    

        

            
Name
            
Price
            
CreatedDate
            
UpdatedDate
            

        

                
<%= u.Name%>
                
<%= u.Price %>
                
<%= u.CreatedDate %>
                
<%= u.UpdatedDate%>
                

                    <%: Html.ActionLink("Edit", "Edit", new { id=u.Id }) %> |
                    <%: Html.ActionLink("Details", "Details", new { id=u.Id }) %> |
                    <%: Html.ActionLink("Delete", "Delete", new { id=u.Id }) %>
                
            

        

        <% if ((string)ViewData["pageLinks"] != "")
           { %>
           <%= ViewData["pageLinks"] %>
           


        <% } %>       
    <% } %>
