The quick start guides you through the steps of adding an OLAP control in a web application and displaying data in it.

Follow the steps given below to get started:

Create an MVC Application

Create a new MVC application using the ComponentOne or VisualStudio templates. For more information about creating an MVC application, see Configuring your MVC Application topic.

Create a Datasource for OLAP

Create a new class inside the Models folder to create a data source for the OLAP control.

1. Add a new class to the folder Models (for example: ProductData.cs). For more information about how to add a new model, see Adding controls.
2. Add the following code to the model to define the data for OLAP.
   • C#

   using System;
   using System.Collections.Generic;
   using System.Data;
   using System.Linq;
   using System.Web;
   
   namespace OlapSample.Models
   {
       public class ProductData
       {
           private static Random r = new Random();
           public int ID { get; set; }
           public string Product { get; set; }
           public string Country { get; set; }
           public DateTime Date { get; set; }
           public int Sales { get; set; }
           public int Downloads { get; set; }
           public bool Active { get; set; }
           public double Discount { get; set; }
   
           private static int randomInt(int max)
           {
               return (int)Math.Floor(r.NextDouble() * (max + 1));
           }
           public static IEnumerable<ProductData> GetData(int cnt)
           {
               string[] countries = "China,India,Russia,US,Germany,UK,Japan,Italy,Greece,Spain,Portugal".Split(',');
               string[] products = "Wijmo,Aoba,Xuni,Olap".Split(',');
               List<ProductData> result = new List<ProductData>();
               for (var i = 0; i < cnt; i++)
               {
                   result.Add(new ProductData
                   {
                       ID = i,
                       Product = products[randomInt(products.Length - 1)],
                       Country = countries[randomInt(countries.Length - 1)],
                       Date = new DateTime(2015, randomInt(5) + 1, randomInt(27) + 1),
                       Sales = randomInt(10000),
                       Downloads = randomInt(10000),
                       Active = randomInt(1) == 1 ? true : false,
                       Discount = r.NextDouble()
                   });
               }
               return result;
           }
       }
   }
   

Add an OLAP control

Create a Controller and View for OLAP control and follow the below steps to initialize an OLAP control.

Add a new Controller

1. In the Solution Explorer, right click the folder Controllers.
2. From the context menu, select Add | Controller. The Add Scaffold dialog appears.
3. Complete the following steps in the Add Scaffold dialog:
   1. Select Empty MVC Controller template.
   2. Set name of the controller (for example: OlapController).
   3. Click Add.
4. Replace the method Index() with the following method.
   • C#

   public class OlapController : Controller
   {
       private static System.Collections.IEnumerable Data = ProductData.GetData(10).ToList();
       // GET: PivotGrid
       public ActionResult Index()
       {
           return View(Data);
       }
   }
   

1. From the Solution Explorer, expand the folder Controllers and double click the OlapController.
2. Place the cursor inside the method Index().
3. Right click and select Add View. The Add View dialog appears.
4. In the Add View dialog, verify that the view name is Index and View engine is Razor (CSHTML).
5. Click Add to add a view is for the controller. Copy the following code and paste it inside Index.cshtml.

   Razor

   Copy Code

   @model IEnumerable<ProductData> <c1-pivot-engine id="indexEngine"> <c1-items-source source-collection="Model"></c1-items-source> <c1-view-field-collection c1-property="RowFields" items="Country"></c1-view-field-collection> <c1-view-field-collection c1-property="ColumnFields" items="Product"></c1-view-field-collection> <c1-view-field-collection c1-property="ValueFields" items="Sales"></c1-view-field-collection> </c1-pivot-engine> <c1-pivot-panel items-source-id="indexEngine"></c1-pivot-panel> <c1-pivot-chart items-source-id="indexEngine"></c1-pivot-chart> <c1-pivot-grid items-source-id="indexEngine"></c1-pivot-grid>

Build and Run the Project

1. Click Build | Build Solution to build the project.
2. Press F5 to run the project.
   Append the folder name and view name to the generated URL (for example: http://localhost:1234/Olap/Index) in the address bar of the browser to see the view.
