In this article we are going to see how to create a custom deferred grid in MVC using Web API and Angular JS. We will be creating a custom UI for the grid and using web API and angular JS $http services we will fetch the data from the database. Normally we uses ADO.Net Entity data model as the model class when we work with a Web API right? Instead of using an Entity data model, here we are going to use our normal SqlDataAdapter and SqlConnection and stored procedure to get the data from our database. We uses Virtual Repeat in Angular JS for loading the data in UI, so that the data will be loaded when ever there is a user action that is scrolling (Virtual Scrolling). So that in the view port we will load only few items first. Now shall we go and see this in detail? I hope you will like this.

Download the source code

You can always download the source code here:

  • Custom Deferred Grid Using MVC Web API And Angular JS
  • Trials Database SQL Script
  • Background

    We have so many plugins available to show the data in a grid format. Isn’t it? if you want to know few of them, you can find it here. Now what if you need to show the data in a grid format without using any additional plugins? What if you need to load the data to that grid dynamically that is whenever user scrolls the grid? If you could not find the answer for these questions, here in this post I am going to share an option. I hope you will enjoy reading.

    Create a MVC application

    Click File-> New-> Project then select MVC application. Before going to start the coding part, make sure that Angular JS is installed. You can all the items mentioned above from NuGet. Right click on your project name and select Manage NuGet packages.

    Angular JS NuGet Package Visual Studio

    Angular JS NuGet Package Visual Studio

    Once you have installed, please make sure that all the items are loaded in your scripts folder.

    Using the code

    I hope everything is set now, then it is time to start our coding. First we will create a controller action and a view. Below is the code snippet of our controller.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.Mvc;
    namespace Custom_Deffered_Grid_Using_MVC_Web_API_And_Angular_JS.Controllers
    {
        public class DefaultController : Controller
        {
            // GET: Default
            public ActionResult Index()
            {
                return View();
            }
        }
    }
    

    Here Default/em> is my controller name. Now create a view for this action, and load the needed references.

    
    @{
        ViewBag.Title = "Index";
    }
    
    <h2>Index</h2>
    <link href="~/Content/angular-material.css" rel="stylesheet" />
    <script src="~/scripts/angular.min.js"></script>
    <script src="~/scripts/angular-route.min.js"></script>
    <script src="~/scripts/angular-aria.min.js"></script>
    <script src="~/scripts/angular-animate.min.js"></script>
    <script src="~/scripts/angular-messages.min.js"></script>
    <script src="~/scripts/angular-material.js"></script>
    <script src="~/scripts/svg-assets-cache.js"></script>
    <script src="~/scripts/Default/Default.js"></script>
    

    You can get this files from the source code attached with this article. And the file Default.js is the additional file where we are requested to do our additional scripts. So far the basic implementation of our view is done. Now we will create a Web API and additional model class to fetch the data from the database. Are you ready?

    Below is my Web API controller.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Net;
    using System.Net.Http;
    using System.Web.Http;
    using Custom_Deffered_Grid_Using_MVC_Web_API_And_Angular_JS.Models;
    namespace Custom_Deffered_Grid_Using_MVC_Web_API_And_Angular_JS.Controllers
    {
        public class DataAPIController : ApiController
        {
            DataModel dm = new DataModel();
            public string getData(int id)
            {
                var d = dm.fetchData(id);
                return d;
            }
        }
    
    }
    

    Have you noticed that I have included using Custom_Deffered_Grid_Using_MVC_Web_API_And_Angular_JS.Models; in the section? This is to ensure that we can use the model classes whatever we have creates so far. In this case DataModel is our model class and we are creating an instance for the same.

    DataModel dm = new DataModel();
    

    The controller action getData accepting the parameter id right? This is actually the page offset value which we are passing from the client side. Now we will create our model class, you can find the code snippets below for that.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Data;
    using System.Data.Sql;
    using System.Data.SqlClient;
    using System.Configuration;
    namespace Custom_Deffered_Grid_Using_MVC_Web_API_And_Angular_JS.Models
    {
        public class DataModel
        {
            public string fetchData(int pageOffset)
            {
                string connection = ConfigurationManager.ConnectionStrings["TrialsDBEntities"].ConnectionString;
                using (SqlConnection cn = new SqlConnection(connection))
                {
                    SqlCommand cmd = new SqlCommand("usp_Get_SalesOrderDetailPage", cn);
                    cmd.Parameters.Add("@pageoffset", SqlDbType.Int).Value = pageOffset;
                    cmd.CommandType = CommandType.StoredProcedure;
                    try
                    {
                        DataTable dt = new DataTable();
                        SqlDataAdapter da = new SqlDataAdapter(cmd);
                        cn.Open();                    
                        da.Fill(dt);
                        return GetJson(dt);
                    }
                    catch (Exception)
                    {
                        throw;
                    }
    
                }
            }
        }
    }
    

    As I said before, instead of using an entity model we uses our normal sql connections and sql data adapter to load the data. Before going to use this function, please make sure that you have added the below references.

    using System.Data;
    using System.Data.Sql;
    using System.Data.SqlClient;
    using System.Configuration;
    

    Now coming back to the fetchData function , We uses the connection string TrialsDBEntities from the web config file. So it is mandatory that you must have a connection string with that name in your web config file. Once that is done, we calls the stored procedure usp_Get_SalesOrderDetailPage and fill the data using SqlDataAdapter.

    Another thing to be notified here is we are passing that DataTable to a function called GetJson. So you must have the definition for that too.

     public string GetJson(DataTable dt)
            {
                try
                {
                    if (dt == null)
                    {
                        throw new ArgumentNullException("dt");
                    }
                    System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
                    List<Dictionary<string, object>> rows =
                      new List<Dictionary<string, object>>();
                    Dictionary<string, object> row = null;
                    foreach (DataRow dr in dt.Rows)
                    {
                        row = new Dictionary<string, object>();
                        foreach (DataColumn col in dt.Columns)
                        {
                            row.Add(col.ColumnName.Trim(), dr[col]);
                        }
                        rows.Add(row);
                    }
                    return serializer.Serialize(rows);
                }
                catch (Exception)
                {
                    throw;
                }
            }
    

    What this function does it, converting the data table to a JSON format. So far, the coding related to Web API is done, now it is time to create a database, table, a stored procedure.

    Create a database

    The following query can be used to create a database in your SQL Server.

    USE [master]
    GO
    
    /****** Object:  Database [TrialsDB]    Script Date: 25-Feb-16 12:34:32 PM ******/
    CREATE DATABASE [TrialsDB]
     CONTAINMENT = NONE

    GO
    
    ALTER DATABASE [TrialsDB] SET COMPATIBILITY_LEVEL = 110
    GO
    
    IF (1 = FULLTEXTSERVICEPROPERTY('IsFullTextInstalled'))
    begin
    EXEC [TrialsDB].[dbo].[sp_fulltext_database] @action = 'enable'
    end
    GO
    
    ALTER DATABASE [TrialsDB] SET ANSI_NULL_DEFAULT OFF 
    GO
    
    ALTER DATABASE [TrialsDB] SET ANSI_NULLS OFF

    ALTER DATABASE [TrialsDB] SET  DISABLE_BROKER 
    GO
    
    ALTER DATABASE [TrialsDB] SET AUTO_UPDATE_STATISTICS_ASYNC OFF 
    GO
    
    ALTER DATABASE [TrialsDB] SET DATE_CORRELATION_OPTIMIZATION OFF 
    GO
    
    ALTER DATABASE [TrialsDB] SET TRUSTWORTHY OFF 
    GO
    
    ALTER DATABASE [TrialsDB] SET ALLOW_SNAPSHOT_ISOLATION OFF

    ALTER DATABASE [TrialsDB] SET HONOR_BROKER_PRIORITY OFF 
    GO
    
    ALTER DATABASE [TrialsDB] SET RECOVERY FULL 
    GO
    
    ALTER DATABASE [TrialsDB] SET  MULTI_USER

    ALTER DATABASE [TrialsDB] SET TARGET_RECOVERY_TIME = 0 SECONDS 
    GO
    
    ALTER DATABASE [TrialsDB] SET  READ_WRITE 
    GO
    

    Now we will create a table 🙂

    Create table in database

    Below is the query to create table in database.

    USE [TrialsDB]
    GO
    
    /****** Object:  Table [dbo].[SalesOrderDetail]    Script Date: 25-Feb-16 12:35:45 PM ******/
    SET ANSI_NULLS ON
    GO
    
    SET QUOTED_IDENTIFIER ON
    GO
    
    CREATE TABLE [dbo].[SalesOrderDetail](
    	[SalesOrderID] [int] NOT NULL,
    	[SalesOrderDetailID] [int] IDENTITY(1,1) NOT NULL,
    	[CarrierTrackingNumber] [nvarchar](25) NULL,
    	[OrderQty] [smallint] NOT NULL,
    	[ProductID] [int] NOT NULL,
    	[SpecialOfferID] [int] NOT NULL,
    	[UnitPrice] [money] NOT NULL,
    	[UnitPriceDiscount] [money] NOT NULL,
    	[LineTotal]  AS (isnull(([UnitPrice]*((1.0)-[UnitPriceDiscount]))*[OrderQty],(0.0))),
    	[rowguid] [uniqueidentifier] ROWGUIDCOL  NOT NULL,
    	[ModifiedDate] [datetime] NOT NULL,
     CONSTRAINT [PK_SalesOrderDetail_SalesOrderID_SalesOrderDetailID] PRIMARY KEY CLUSTERED 
    (
    	[SalesOrderID] ASC,
    	[SalesOrderDetailID] ASC
    )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
    ) ON [PRIMARY]
    
    GO
    

    Can we insert some data to the table now?

    Insert data to table

    To insert the data, I will attach a database script file along with the download file, you can either run that or insert some data by using the below query. By the way if you would like to know how to generate scripts with data in SQL Server, you can check here.

    USE [TrialsDB]
    GO
    
    INSERT INTO [dbo].[SalesOrderDetail]
               ([SalesOrderID]
               ,[CarrierTrackingNumber]
               ,[OrderQty]
               ,[ProductID]
               ,[SpecialOfferID]
               ,[UnitPrice]
               ,[UnitPriceDiscount]
               ,[rowguid]
               ,[ModifiedDate])
         VALUES
               (<SalesOrderID, int,>
               ,<CarrierTrackingNumber, nvarchar(25),>
               ,<OrderQty, smallint,>
               ,<ProductID, int,>
               ,<SpecialOfferID, int,>
               ,<UnitPrice, money,>
               ,<UnitPriceDiscount, money,>
               ,<rowguid, uniqueidentifier,>
               ,<ModifiedDate, datetime,>)
    GO
    

    Along with this, we can create a new stored procedure which will fetch the data. Following is the query to create the stored procedure.

    USE [TrialsDB]
    GO
    /****** Object:  StoredProcedure [dbo].[usp_Get_SalesOrderDetailPage]    Script Date: 25-Feb-16 12:53:07 PM ******/
    SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO
    -- =============================================
    -- Author:		<Author,Sibeesh Venu>
    -- Create date: <Create Date, 18-Feb-2016>
    -- Description:	<Description,To fetch SalesOrderDetail Page Wise>
    -- =============================================
    ALTER PROCEDURE [dbo].[usp_Get_SalesOrderDetailPage] @pageOffset int=0 AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from
     -- interfering with SELECT statements.
    
    SET NOCOUNT ON;
    
    WITH CTE_Sales(SlNo, SalesOrderID,SalesOrderDetailID,CarrierTrackingNumber,OrderQty,ProductID,UnitPrice,ModifiedDate) AS
      ( SELECT ROW_NUMBER() over (
                                  ORDER BY ModifiedDate DESC) AS SlNo,
                            SalesOrderID,
                            SalesOrderDetailID,
                            CarrierTrackingNumber,
                            OrderQty,
                            ProductID,
                            UnitPrice,
                            ModifiedDate
       FROM dbo.SalesOrderDetail)
    SELECT *
    FROM CTE_Sales
    WHERE SlNo>=@pageOffset
      AND SlNo<@pageOffset+10 END
    
    --[usp_Get_SalesOrderDetailPage] 4
    

    Here we are using Common Table Expressions in SQL Server. If you are new to CTE, you can always see here Common Table Expression Example for some more informations regarding that. It seems the database is ready with the data now. Then we can go back to our view. We will change our view as follows with the custom styles.

    
    @{
        ViewBag.Title = "Index";
    }
    
    <h2>Index</h2>

    As you can see form the above code, our Angular JS controller is ng-controller=”AppCtrl as ctrl” and the Angular JS app is ng-app=”MyApp”. We uses md-virtual-repeat as a repeater control, so that it can be used to loop through the object item in ctrl.dynamicItems. Now it is time to create our Angular JS scripts. Shall we?

    We can create our Angular App and Controller as follows.

    (function () {
        'use strict';
        angular
          .module('MyApp', ['ngMaterial', 'ngMessages', 'material.svgAssetsCache'])
          .controller('AppCtrl', function ($http, $timeout) {
          });
    })();
    

    Now in the controller we will add a function with some predefined items as follows.

     var DynamicItems = function () {
                  this.loadedPages = {};
                  this.numItems = 0;
                  this.PAGE_SIZE = 10;
                  this.fetchNumItems_();
              };
    

    Here loadedPages is the data collection which is keyed by the page number (Our parameter id in the controller). And numItems is the total number of items. PAGE_SIZE is the number of items to be fetched from each requests.

    Now we will create a function to calculate the length of the records.

    DynamicItems.prototype.getLength = function () {
                  return this.numItems;
              };
    

    This numItems can be set in the below function.

    DynamicItems.prototype.fetchNumItems_ = function () {
                  $timeout(angular.noop, 300).then(angular.bind(this, function () {
                      this.numItems = 1000;
                  }));
              };
    

    Here we are setting the numItems as 1000 for demo purposes, you can always get the count from database and assign it here with a $http request as we load the data from database here, you are yet to see that, no worries.

    Below is the function to get the item by index.

     DynamicItems.prototype.getItemAtIndex = function (index) {
                  var pageNumber = Math.floor(index / this.PAGE_SIZE);
                  var page = this.loadedPages[pageNumber];
    
                  if (page) {
                      return page[index % this.PAGE_SIZE];
                  } else if (page !== null) {
                      this.fetchPage_(pageNumber);
                  }
              };
    

    Here is the main part that to load the data from database using a $http service in Angular JS.

     DynamicItems.prototype.fetchPage_ = function (pageNumber) {
                  this.loadedPages[pageNumber] = null;
                  $timeout(angular.noop, 300).then(angular.bind(this, function () {
                      var thisObj = this;
                      this.loadedPages[pageNumber] = [];
                      var pageOffset = pageNumber * this.PAGE_SIZE;
                      var myData;
                      var url = '';
                      url = 'api/DataAPI/' + pageOffset;
                      $http({
                          method: 'GET',
                          url: url,
                      }).then(function successCallback(response) {
                          // this callback will be called asynchronously
                          // when the response is available
                          myData = JSON.parse(response.data);
                          pushLoadPages(thisObj, myData)
                      }, function errorCallback(response) {
                          console.log('Oops! Something went wrong while fetching the data. Status Code: ' + response.status + ' Status statusText: ' + response.statusText);
                          // called asynchronously if an error occurs
                          // or server returns response with an error status.
                      });
                  }));
              };
    

    As you can see calls our Web API ( url = ‘api/DataAPI/’ + pageOffset;) from $http service, the callback function successCallback will get the data from database as a response. Once we get the response, we will pass the data to a function pushLoadPages to push the data items to the loadedPages. Cool right? Below is the code snippets for that function.

    function pushLoadPages(thisObj, servData) {
                          if (servData != undefined) {
                              for (var i = 0; i < servData.length; i++) {
                                  thisObj.loadedPages[pageNumber].push(servData[i]);
                              }
                          }
                      }
    

    Here is the complete code for our Angular JS.
