How Can I Convert My Paging Functionality To Use AJAX Insead?

Question

I currently have pagination working in my MVC 3 project using the PagedList library (https://github.com/TroyGoode/PagedList).

I would like to convert this code to update the page using ajax with the new results rather then refreshing the whole page. I'm not really sure how to go about that. Im rather new to MVC coming from Webforms. Any help would be greatly appreciated!

Heres my code:

Home Controller:

//#####################################
// ActionResult = Retrieve Comments
//#####################################
[ChildActionOnly]
public ActionResult _Comments(int ProductID, int? Page)
{
    //Perform the Database Query.
    try
    {
        //SQL Query - Get * records
        var Model = from r in DB.Comments where r.ProductID == ProductID select r;

        //Page number passed in via url. Default to 1 if not specified.
        var PageNumber = Page ?? 1;

        //Grab 6 results from the result set.
        var Results = Model.ToPagedList(PageNumber, 6);

        //Store Paged Result set in ViewBag for Paging.
        ViewBag.Results = Results;

        //Store in ViewBag for display (Page 1 of 43)
        ViewBag.PageNumber = PageNumber;

        //Get Total Pages: Divide Total Records by 6 Records per page.
        ViewBag.PageCount = Model.Count() / 6 + 1; 

        //Return Records to my view.
        return PartialView(Results);
    }
    //There was an error.
    catch
    {
        //ViewBag.ErrorMessage = ex;
        return PartialView("Error");
    }
}

PartialView: _Comments

@model IEnumerable<DH.Models.Comment>

@using PagedList.Mvc;
@using PagedList;

@{  
    //No Comments Yet
    if (@Model.Count() == 0)
    {
        <div id="CommentStatus">Be the first to comment on this product!</div>
    }
    //There are comments!
    else
    {
        foreach (var item in Model)
        {   
             //html for writing out the comments...
        }
    }
}

<div>Page @ViewBag.PageNumber of @ViewBag.PageCount</div>

@Html.PagedListPager((IPagedList)ViewBag.Results, Page => Url.Action("Index", new { Page = Page }), new PagedListRenderOptions { LinkToPreviousPageFormat = "< Prev", LinkToNextPageFormat = "Next >", LinkToLastPageFormat = "&Uacute;ltima >>" })

Model

namespace DH.Models
{
    public class Comment
    {  
        public int CommentID { get; set; }

        public int ProductID { get; set; }

        public string Author { get; set; }

        public string Message { get; set; }

        public DateTime MessageDate { get; set; }

        public int ThumbsUp { get; set; }

        public int ThumbsDown { get; set; }

        public string IP { get; set; }
    }
}

Poking around it looks like I need to use Ajax.Beginform? – Maddhacker24 May 13 '12 at 04:25 — Maddhacker24, May 13 '12 at 04:25

I'm the creator of the PagedList nuget package.

There is an example of doing Ajax pagination (as well as infinite scrolling) in the project's git repo:

https://github.com/TroyGoode/PagedList/tree/master/src/PagedList.Mvc4.Example

Controller: https://github.com/TroyGoode/PagedList/blob/master/src/PagedList.Mvc4.Example/Controllers/AjaxController.cs

View: https://github.com/TroyGoode/PagedList/blob/master/src/PagedList.Mvc4.Example/Views/Ajax/Index.cshtml

It looks like the links have moved. The Controller is now [here](https://github.com/TroyGoode/PagedList/blob/master/src/PagedList.Mvc4.Example/Controllers/AjaxController.cs) and the View is now [here](https://github.com/TroyGoode/PagedList/blob/master/src/PagedList.Mvc4.Example/Views/Ajax/Index.cshtml). – Splendor Dec 04 '12 at 22:42

you can easily do it with knockout and pagedlist package

   <script type="text/javascript">
$(function() {
    $('#users').pagify({
        dataUrl: '/User/UserLisr',
        callBack: function(){
           // Ajax remove preloader and some other callbacks  
        },
        beforeSend: function(){
           // Ajax show preloader and some other function before start
        }
    });
}
</script>

pagify.mvc package
