Creating a simple application with pivot client and relational data sources (client mode)
This section covers the information required to populate a simple pivot client with Relational
data completely on the client-side
.
Scripts and CSS references
Create an HTML page and add scripts and style sheets that are required to render a pivot client widget that are listed below in the appropriate order:
- ej.web.all.min.css
- jQuery-3.0.0.min.js
- ej.web.all.min.js
- jsrender.min.js
Initialize pivot client
Place a div tag in the HTML page which acts as a container for the pivot client widget. Then, initialize the widget using the “ejPivotClient” method.

</div>
<script type="text/javascript">
$(function () {
//Set properties and initialize ejPivotClient widget
$("#PivotClient1").ejPivotClient();
});
</script>

</html>
Populate pivot client with data
This section explains the steps to populate the pivot client control using a sample JSON data as shown below:
var pivotData = [
{ Amount: 100, Country: "Canada", Date: "FY 2005", Product: "Bike", Quantity: 2, State: "Alberta" },
{ Amount: 200, Country: "Canada", Date: "FY 2006", Product: "Van", Quantity: 3, State: "British Columbia" },
{ Amount: 300, Country: "Canada", Date: "FY 2007", Product: "Car", Quantity: 4, State: "Brunswick" },
{ Amount: 150, Country: "Canada", Date: "FY 2008", Product: "Bike", Quantity: 3, State: "Manitoba" },
{ Amount: 200, Country: "Canada", Date: "FY 2006", Product: "Car", Quantity: 4, State: "Ontario" },
{ Amount: 100, Country: "Canada", Date: "FY 2007", Product: "Van", Quantity: 1, State: "Quebec" },
{ Amount: 200, Country: "France", Date: "FY 2005", Product: "Bike", Quantity: 2, State: "Charente-Maritime" },
{ Amount: 250, Country: "France", Date: "FY 2006", Product: "Van", Quantity: 4, State: "Essonne" },
{ Amount: 300, Country: "France", Date: "FY 2007", Product: "Car", Quantity: 3, State: "Garonne (Haute)" },
{ Amount: 150, Country: "France", Date: "FY 2008", Product: "Van", Quantity: 2, State: "Gers" },
{ Amount: 200, Country: "Germany", Date: "FY 2006", Product: "Van", Quantity: 3, State: "Bayern" },
{ Amount: 250, Country: "Germany", Date: "FY 2007", Product: "Car", Quantity: 3, State: "Brandenburg" },
{ Amount: 150, Country: "Germany", Date: "FY 2008", Product: "Car", Quantity: 4, State: "Hamburg" },
{ Amount: 200, Country: "Germany", Date: "FY 2008", Product: "Bike", Quantity: 4, State: "Hessen" },
{ Amount: 150, Country: "Germany", Date: "FY 2007", Product: "Van", Quantity: 3, State: "Nordrhein-Westfalen" },
{ Amount: 100, Country: "Germany", Date: "FY 2005", Product: "Bike", Quantity: 2, State: "Saarland" },
{ Amount: 150, Country: "United Kingdom", Date: "FY 2008", Product: "Bike", Quantity: 5, State: "England" },
{ Amount: 250, Country: "United States", Date: "FY 2007", Product: "Car", Quantity: 4, State: "Alabama" },
{ Amount: 200, Country: "United States", Date: "FY 2005", Product: "Van", Quantity: 4, State: "California" },
{ Amount: 100, Country: "United States", Date: "FY 2006", Product: "Bike", Quantity: 2, State: "Colorado" },
{ Amount: 150, Country: "United States", Date: "FY 2008", Product: "Car", Quantity: 3, State: "New Mexico" },
{ Amount: 200, Country: "United States", Date: "FY 2005", Product: "Bike", Quantity: 4, State: "New York" },
{ Amount: 250, Country: "United States", Date: "FY 2008", Product: "Car", Quantity: 3, State: "North Carolina" },
{ Amount: 300, Country: "United States", Date: "FY 2007", Product: "Van", Quantity: 4, State: "South Carolina" }
];
Now, set the JSON data to the “data” property present in the “dataSource” object. The “dataSource” object allows you to set both the raw data input and fields that need to be displayed in the row, column, value, and filter sections of the pivot client control.
<!DOCTYPE html>
<html>
//……
<body>
<div id="PivotClient1"></div>
<script type="text/javascript">
//Datasource
var pivotData = [
{ Amount: 100, Country: "Canada", Date: "FY 2005", Product: "Bike", Quantity: 2, State: "Alberta" },
{ Amount: 200, Country: "Canada", Date: "FY 2006", Product: "Van", Quantity: 3, State: "British Columbia" },
{ Amount: 300, Country: "Canada", Date: "FY 2007", Product: "Car", Quantity: 4, State: "Brunswick" },
{ Amount: 100, Country: "Canada", Date: "FY 2007", Product: "Van", Quantity: 1, State: "Quebec" },
{ Amount: 200, Country: "France", Date: "FY 2005", Product: "Bike", Quantity: 2, State: "Charente-Maritime" },
{ Amount: 250, Country: "France", Date: "FY 2006", Product: "Van", Quantity: 4, State: "Essonne" },
....
....
];
$(function () {
$("#PivotClient1").ejPivotClient({
dataSource: {
//Datasource bound to PivotClient control.
data: pivotData,
//Required fields in row, column, value and filter areas of PivotClient control.
rows: [
{
fieldName: "Country",
fieldCaption: "Country"
}
],
columns: [
{
fieldName: "Product",
fieldCaption: "Product"
}
],
values: [
{
fieldName: "Amount",
fieldCaption: "Amount"
}
]
}
});
});
</script>
</body>
</html>
Now, the pivot client is rendered with pivot chart, and the pivot grid is rendered with “Country” field in the row, “Product” field in the column, and “Amount” field in the value section.
The following table will explain the relational
and datasource
properties at client-side
in detail:

Creating a simple application with pivot client and relational data source (server mode)
This section covers the information required to create a simple pivot client bound to Relational
data source from the server-side
.
NOTE
This section illustrates creating a simple web application through Visual Studio IDE, since the pivot client with
server-side
data source requires .NET dependency. The web application contains an HTML page and a service that will transfer the data toserver-side
, process it, and return it to the client-side for control re-rendering. The service utilized for communication can be either WCF or WebAPI based on user requirement. Here, both are illustrated for user convenience.
Project initialization
Create a new ASP.NET Empty Web Application by using Visual Studio IDE and name the project as “PivotClientDemo”.
Next, you should add an HTML page. To add an HTML page in your web application, right-click the project in the solution explorer and select Add > New Item. In the Add New Item window, select HTML Page and name it “GettingStarted.html,” and then click Add.
You can set the “GettingStarted.html” page as start-up page. To do so, right-click the “GettingStarted.html” page and select “Set As Start Page”.
Scripts and CSS initialization
The scripts and style sheets that are mandatorily required to render a pivot client widget in the HTML page are highlighted below:
- ej.web.all.min.css
- jQuery-3.0.0.min.js
- ej.web.all.min.js
- jsrender.min.js
The scripts and style sheets listed above can be found in any of the following locations:
Local disk: Click here to know more about script and style sheets installed in the local machine.
CDN link: Click here to know more about script and style sheets available in online.
NuGet package: Click here to know more about script and style sheets available in NuGet package.
Control initialization
To initialize a pivot client widget, first you can define a div tag with an appropriate id attribute which acts as a container for the pivot client widget. Then, you can initialize the widget using the ejPivotClient
method.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>PivotClient - Getting Started</title>
<link href="http://cdn.syncfusion.com/24.2.3/js/web/flat-azure/ej.web.all.min.css" rel="stylesheet" type="text/css" />
<script src="http://cdn.syncfusion.com/js/assets/external/jquery-3.0.0.min.js" type="text/javascript"></script>
<script src="http://cdn.syncfusion.com/24.2.3/js/web/ej.web.all.min.js" type="text/javascript"></script>
<script src="http://cdn.syncfusion.com/js/assets/external/jsrender.min.js" type="text/javascript"></script>
</head>
<body>
<div>
<!--Create a tag which acts as a container for ejPivotClient widget.-->
<div id="PivotClient1"></div>
<script type="text/javascript">
//Set properties and initialize ejPivotClient widget.
$(function()
{
$("#PivotClient1").ejPivotClient(
{
url: "/Relational"
});
});
</script>
</div>
</body>
</html>
The url
property in the pivot client widget points the service endpoint, where the data is processed and fetched in the form of JSON. The service used for the pivot client widget as endpoint are WCF and WebAPI.
WebAPI
Adding a WebAPI controller
To add a WebAPI controller in your existing web application, right-click the project in the solution explorer and select Add > New Item. In the Add New Item window, select WebAPI Controller Class and name it “RelationalController.cs,” and then click Add.
The WebAPI controller is added to your application, which, in turn, comprises the following file. The utilization of this file will be explained in the immediate sections.
- RelationalController.cs
NOTE
While adding the WebAPI controller class, add the mandatory suffix “Controller”. For example, in the demo, the controller is named as “RelationalController”.
Next, remove all the existing methods such as “Get”, “Post”, “Put”, and “Delete” present in the RelationalController.cs
file.
namespace PivotClientDemo
{
public class RelationalController: ApiController
{
}
}
List of dependency libraries
Next, you can add the below mentioned dependency libraries to your web application. These libraries can be found in the GAC (Global Assembly Cache).
To add them to your web application, right-click References in the solution Explorer and select Add Reference. In the Reference Manager dialog, under Assemblies > Extension, the following Syncfusion libraries are found.
NOTE
If you have installed any version of Essential Studio, then the location of Syncfusion libraries is [system drive:\Program Files (x86)\Syncfusion\Essential Studio\24.2.3\Assemblies].
- Syncfusion.Compression.Base
- Syncfusion.Linq.Base
- Syncfusion.Olap.Base
- Syncfusion.PivotAnalysis.Base
- System.Data.SqlServerCe (Version: 4.0.0.0)
- Syncfusion.XlsIO.Base
- Syncfusion.Pdf.Base
- Syncfusion.DocIO.Base
- Syncfusion.EJ
- Syncfusion.EJ.Export
- Syncfusion.EJ.Pivot
List of namespaces
The following are the list of namespaces to be added on top of the main class in the RelationalController.cs
file.
using Syncfusion.JavaScript;
using Syncfusion.PivotAnalysis.Base;
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlServerCe;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Web;
using System.Web.Http;
using System.Web.Script.Serialization;
using Syncfusion.JavaScript.Olap;
namespace PivotClientDemo
{
public class RelationalController : ApiController
{
}
}
Data source initialization
A simple collection is provided as a data source for the pivot client in this demo section. This data source is placed inside a separate class “ProductSales” in RelationalController.cs
file. Refer to the following code example:
namespace PivotClientDemo
{
………
………
………
internal class ProductSales
{
public string Product { get; set; }
public string Date { get; set; }
public string Country { get; set; }
public string State { get; set; }
public int Quantity { get; set; }
public double Amount { get; set; }
public static ProductSalesCollection GetSalesData()
{
/// Geography
string[] countries = new string[] { "Australia", "Canada", "France", "Germany", "United Kingdom", "United States" };
string[] ausStates = new string[] { "New South Wales", "Queensland", "South Australia", "Tasmania", "Victoria" };
string[] canadaStates = new string[] { "Alberta", "British Columbia", "Brunswick", "Manitoba", "Ontario", "Quebec" };

/// Products
string[] products = new string[] { "Bike", "Van", "Car" };
Random r = new Random(123345345);
int numberOfRecords = 2000;
ProductSalesCollection listOfProductSales = new ProductSalesCollection();
for (int i = 0; i < numberOfRecords; i++)
{
ProductSales sales = new ProductSales();
sales.Country = countries[r.Next(1, countries.GetLength(0))];
sales.Quantity = r.Next(1, 12);
/// 1 percent discount for 1 quantity
double discount = (30000 * sales.Quantity) * (double.Parse(sales.Quantity.ToString()) / 100);
sales.Amount = (30000 * sales.Quantity) - discount;
sales.Date = dates[r.Next(r.Next(dates.GetLength(0) + 1))];
sales.Product = products[r.Next(r.Next(products.GetLength(0) + 1))];
switch (sales.Product)
{
case "Car":
{
sales.Date = "FY 2005";
break;
}
}
switch (sales.Country)
{
case "Australia":
{
sales.State = ausStates[r.Next(ausStates.GetLength(0))];
break;
}
case "Canada":
{

break;
}
case "United Kingdom":
{
sales.State = ukStates[r.Next(ukStates.GetLength(0))];
break;
}
case "United States":
{
sales.State = ussStates[r.Next(ussStates.GetLength(0))];
break;
}
}
listOfProductSales.Add(sales);
}
return listOfProductSales;
}
public override string ToString()
{
return string.Format("{0}-{1}-{2}", this.Country, this.State, this.Product);
}
public class ProductSalesCollection : List<ProductSales>
{
}
}
}
Service methods in WebAPI controller
You can define the service methods in the RelationalController class. To do this, found the RelationalController.cs
file which was created while adding the WebAPI controller class to your web application.

}
}
.....
..... // Initialize the datasource
.....
}
NOTE
The
customObject
is utilized to pass the additional information between the client-end and the service-end.
Configure routing in global application class
To add a Global.asax in your existing web application, right-click the project in the solution explorer and select Add > New item. In the Add New Item window, select Global Application class and name it “Global.asax,” and then click Add.
After adding the Global.asax file, immediately add the namespace “using System.Web.Http;”, and then you can configure the routing as shown in the following code example:
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
System.Web.Http.GlobalConfiguration.Configuration.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional });
AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
}
}
Now, the pivot client is rendered with the pivot chart, and the pivot grid is rendered with “Country” field in the row, “Product” field in the column, and “Amount” field in the value section.
WCF
This section demonstrates the utilization of WCF service as endpoint binding Relational
data source to a simple pivot client. For more details on this topic, click here.
