How do I do pagination in ASP.NET MVC?

Well, what is the data source? Your action could take a few defaulted arguments, i.e.

ActionResult Search(string query, int startIndex, int pageSize) {...}

defaulted in the routes setup so that startIndex is 0 and pageSize is (say) 20:

        routes.MapRoute("Search", "Search/{query}/{startIndex}",
                        new
                        {
                            controller = "Home", action = "Search",
                            startIndex = 0, pageSize = 20
                        });

To split the feed, you can use LINQ quite easily:

var page = source.Skip(startIndex).Take(pageSize);

(or do a multiplication if you use "pageNumber" rather than "startIndex")

With LINQ-toSQL, EF, etc - this should "compose" down to the database, too.

You should then be able to use action-links to the next page (etc):

<%=Html.ActionLink("next page", "Search", new {
                query, startIndex = startIndex + pageSize, pageSize }) %>

I wanted to cover a simple way of doing this with the front end too:

Controller:

public ActionResult Index(int page = 0)
{
    const int PageSize = 3; // you can always do something more elegant to set this

    var count = this.dataSource.Count();

    var data = this.dataSource.Skip(page * PageSize).Take(PageSize).ToList();

    this.ViewBag.MaxPage = (count / PageSize) - (count % PageSize == 0 ? 1 : 0);

    this.ViewBag.Page = page;

    return this.View(data);
}

View:

@* rest of file with view *@

@if (ViewBag.Page > 0)
{
    <a href="@Url.Action("Index", new { page = ViewBag.Page - 1 })" 
       class="btn btn-default">
        &laquo; Prev
    </a>
}
@if (ViewBag.Page < ViewBag.MaxPage)
{
    <a href="@Url.Action("Index", new { page = ViewBag.Page + 1 })" 
       class="btn btn-default">
        Next &raquo;
    </a>
}

I had the same problem and found a very elegant solution for a Pager Class from

http://blogs.taiga.nl/martijn/2008/08/27/paging-with-aspnet-mvc/

In your controller the call looks like:

return View(partnerList.ToPagedList(currentPageIndex, pageSize));

and in your view:

<div class="pager">
    Seite: <%= Html.Pager(ViewData.Model.PageSize, 
                          ViewData.Model.PageNumber,
                          ViewData.Model.TotalItemCount)%>
</div>

Here's a link that helped me with this.

It uses PagedList.MVC NuGet package. I'll try to summarize the steps

1. Install the PagedList.MVC NuGet package

2. Build project

3. Add using PagedList; to the controller

4. Modify your action to set page public ActionResult ListMyItems(int? page) { List list = ItemDB.GetListOfItems(); int pageSize = 3; int pageNumber = (page ?? 1); return View(list.ToPagedList(pageNumber, pageSize)); }

5. Add paging links to the bottom of your view @*Your existing view*@ Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount @Html.PagedListPager(Model, page => Url.Action("Index", new { page, sortOrder = ViewBag.CurrentSort, currentFilter = ViewBag.CurrentFilter }))
