How can i do paging in asp.net mvc3?

I am working on asp.net mvc3 application and have many records coming from database. I want to display only 10 records first then user can click on button to see next 10 records and so on... Like facebook wall posting more开发者_StackOverflow中文版 records.

How can I implement this thing in my application using jQuery and ajax?

How can I control display data in view using paging?

var Entity = (from a
    in context.Data
    where <Condition>
    select a).Take(10);

The following articles should give you an idea :

http://weblogs.asp.net/andrewrea/archive/2008/07/01/asp-net-mvc-quot-pager-quot-html-helper.aspx

http://weblogs.asp.net/gunnarpeipman/archive/2010/02/21/simple-pager-for-asp-net-mvc.aspx

On the other hand, you can implement it like this :

Get the nuget package called TugberkUg.MVC

Then, your controller should look like below :

    public ActionResult Index(int page = 0) {

        const int pageSize = 10;

        #region _filter the model

        IQueryable<myModel> model = _myrepo.GetAll()

        #endregion

        #region _convert the model to paginatedList

        var paginatedModel = 
            new TugberkUg.MVC.Helpers.PaginatedList<myModel>(model, page, pageSize);

        #endregion

        return View(paginatedModel);
    }

And, here how your controller should look like :

@model TugberkUg.MVC.Helpers.PaginatedList<myModel>

@foreach(var item in Model) { 

     <p>@item.id</p>

}

You need to handle the pager as well and here is a sample for you :

ASP.NET MVC PaginatedList Pager - Put wise "..." after certain point

This TugberkUg.MVC.Helpers.PaginatedList class will provide all the necessary fields for pager.

I'm not aware of any .net library that will do pagination for you out of the box, so I will roll out a DIY solution for you to think about.

How can i implement this thing in my application using jquery and ajax?

It is probably wise to have a specific Controller for ajax requests. Just have a separate Area (Ajax), and send your ajax requests to that url you set up.

How can i control display data in view using paging?

Set up a controller that takes in a "page" parameter.

public ActionResult GetData(int? page){ // page is nullable to allow for default page

// Do your query here to get the specific page.

}

I'm not sure if you require more information other than this. If I were trying to do what you were doing, this is what I would do. Hope that helps.

If your are using Webgrid to display data then rowsperpage will do.

 var grid = new WebGrid(source: Model, selectionFieldName: "SelectedRow", rowsPerPage: 10, canPage: true, canSort: true);

I would suggest using a telerik mvc control. They are really easy to use, powerful and free.
