A class for creating different types of pagination link in ASP.NET MVC.

Introduction

I was looking for a pagination class to use in ASP.NET MVC. I found ASP.NET MVC: PagedList<T> and ASP.NET MVC - Pagination View User Control. But I wanted an easier and customizable pagination class. I have developed many projects using the CodeIgniter framework and that time I found their pagination class is better and easier to use. So, I have decided to prepare a pagination class like this for ASP.NET MVC.

Using the Code

Controller

In your controller, to get your current (i.e. selected) page number page put this code snippet.

string pageString = "";

try
{
    pageString = Request.Url.Segments[3];
}
catch (Exception)
{
    pageString = null;
}

int page = (String.IsNullOrEmpty(pageString)) ? 1 : Int32.Parse(pageString);

Here 3 is the segment which holds the page number. It can vary as per your URL.

Then use the pagination class as shown in the following example.

Pagination pagination = new Pagination();

pagination.BaseUrl      = "/Users/List/";
pagination.TotalRows    = totalRows;
pagination.CurPage      = page;
pagination.PerPage      = 10;

string pageLinks = pagination.GetPageLinks();

int start   = (page - 1) * pagination.PerPage;
int offset  = pagination.PerPage;

In BaseUrl you can write a full path like http://www.sitename.com/Controller/Action/ or relative path like /Controller/Action/. Here start is the number from which row should be counted and offset is the number of rows that should be returned. totalRows is the total number of rows.

Now you can use this pageLinks string which is the generated page link.

Next, set your data in the ViewData like the following.

ViewData["title"]       = "Pagination in Asp.Net Mvc";
ViewData["totalRows"]   = totalRows;
ViewData["result"]      = result;
ViewData["pageLinks"]   = pageLinks;

Here, totalRows is the total number of rows and result is the desired resultset.

View

In view page, you can show the page link as follows:

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

   <%= ViewData["pageLinks"] %>
   <br /><br />
<% } %>

Model

You can create a model and make two methods to get total rows and the data from table using LINQ, as shown in the following example.

public int GetTotalUsers()
{
    return new MyDataContext().Users.Count();
}

public List<User> GetUsers(int start, int offset)
{
    var users = new MyDataContext().Users.Skip(start)
                                         .Take(offset);

    return users.ToList();
}

Configuration Settings

General Properites
`BaseUrl`	Full or relative URL to the controller/action (Mandatory).
`TotalRows`	Total number of rows in your resultset (Mandatory).
`CurPage`	Current page number, default 1 (Mandatory).
`PerPage`	Number of items you want to show per page (Optional).
`NumLinks`	Number of "digit" links before and after the current page number (Optional).
`ItemType`	Item type enumeration value (Optional).

Link Properites
`FirstLink`	The text to be shown in the "first" link on the left.
`NextLink`	The text to be shown in the "next" page link.
`PrevLink`	The text to be shown in the "previous" page link.
`LastLink`	The text to be shown in the "last" link on the right.

Tag Properties
`FullTagOpen`	The opening tag placed on the left side of the entire result.
`FullTagClose`	The closing tag placed on the right side of the entire result.
`FirstTagOpen`	The opening tag for the "first" link.
`FirstTagClose`	The closing tag for the "first" link.
`LastTagOpen`	The opening tag for the "last" link.
`LastTagClose`	The closing tag for the "last" link.
`CurTagOpen`	The opening tag for the "current" link.
`CurTagClose`	The closing tag for the "current" link.
`NextTagOpen`	The opening tag for the "next" link.
`NextTagClose`	The closing tag for the "next" link.
`PrevTagOpen`	The opening tag for the "previous" link.
`PrevTagClose`	The closing tag for the "previous" link.
`NumTagOpen`	The opening tag for the "digit" link.
`NumTagClose`	The closing tag for the "digit" link.
`ItemTagOpen`	The opening tag for the "Item".
`ItemTagClose`	The closing tag for the "Item".

You can set configuration settings in three ways.

Set as regular property is set. Example:

objPagination.PerPage  = 10;
objPagination.PrevLink = "Prev";
objPagination.NextLink = "Next";

Put a Pagination.xml file in Content folder and create object of Pagination class as:

Pagination objPagination = new Pagination(true);

Pagination.xml file should be as following pattern as example.

XML

<?xml version="1.0" encoding="utf-8" ?>
<Pagination>
    <NumLinks><![CDATA[5]]></NumLinks>
    <FullTagOpen><![CDATA[<p class='pagination'>]]></FullTagOpen>

    <FullTagClose><![CDATA[</p>]]></FullTagClose>
    <CurTagOpen><![CDATA[<span class='current'>]]></CurTagOpen>
    <CurTagClose><![CDATA[</span>]]></CurTagClose>

</Pagination>

Create any XML file like the above Pagination.xml file and call the method LoadPaginationXml with the file full path as argument. Example:
C#
```
objPagination.LoadPaginationXml("C:\\MyProject\\MyPagination.xml");
```

Different Types of Pagination

By this pagination class you can build different types of page links for your page. Just call the method GetPageLinks with your desired PaginationType as an argument. Example:

objPagination.GetPageLinks(PaginationType.FirstPreviousNextLastItemRight);

You can display item set or item type as follows:

objPagination.ItemType = ItemTypes.Page;

Conclusion

I think thats enough to use this pagination class easily. Bye for this time.

Comments and Discussions

Hello, I made some changes to my customization to support form posts the original pagination uses GET which won't help page a filtered list (unless I missed something), so I added pagination for form posts.

1. Alter the class to support post types
2. Add ajax to post the form
3. Call the class with PaginationActionMethod.Post

Step 1: replace the pagination.cs file

Step 2: Create an AJAX form to post the form for you...
The code below assumes a strongly typed view page of type 'Client' with a SSN, FirstName, LastName textboxes in the form and results being displayed in a div with ID of 'GridPage' that contains the filtered grid & pagination control.

 <script type="text/javascript" language="javascript">
     function PageClient(pageNum) {
         var ssn = $("#SSN").attr("value");
         var fname = $("#FirstName").attr("value");
         var lname = $("#LastName").attr("value");
         $.ajax(
        {
            type: "POST",
            url: "/Client",
            data: "name=" + ssn + "&FirstName=" + fname + "&LastName=" + lname + "&PageNum=" + pageNum,
            dataType: "html",
            success: function(result) {
                var domElement = $(result); // create element from html
                document.getElementById("GridPage").innerHTML = domElement.find("#GridPage").html(); //domElement[60].children[2].childNodes[3].lastChild.outerHTML;

            },
            error: function(error) {
                alert(error);
            }
        });
    }
</script>

Step 3: process the input with the overloaded method.

 [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Index(Client client, string PageNum)
        {
            List<Client> model;
            int skip, take;
            int pageNumber;
            
            if (!string.IsNullOrEmpty(client.SSN) || !string.IsNullOrEmpty(client.FirstName) || !string.IsNullOrEmpty(client.LastName))
            {
                int count = _clientSvc.GetClientCollection().WithSSN(client.SSN).WithFirstName(client.FirstName).WithLastName(client.LastName).Count();
                if (!Int32.TryParse(PageNum, out pageNumber))
                {
                    ViewData["pageLinks"] = Pagination.Paging("#' onclick='return PageClient", Request.Url.Segments, count, out skip, out take, PaginationActionMethod.Post);
                }
                else
                {
                    ViewData["pageLinks"] = Pagination.Paging("#' onclick='return PageClient", pageNumber, count, out skip, out take, PaginationActionMethod.Post);
                }
                model = _clientSvc.GetClientCollection().WithSSN(client.SSN).WithFirstName(client.FirstName).WithLastName(client.LastName).Skip(skip).Take(take).ToList();
            }
            else
            {
                model = _clientSvc.GetClientCollection().ToList();
            }
.....
return View(model);
            }

I hope this helps others. Sorry if I can't offer more insight on the AJAX - it's my first attempt at using it.

Note: if you want to just use the parts I've changed, just do a search on 'James Fleming' in the code
Good Luck!
