</Values>
</DataSource>
<ClientSideEvents Load="onLoad" />
</ej:PivotGrid>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>The values for filtering are given in the GettingStarted.aspx.cs file as shown in the following snippet:
protected void Page_Load(object sender, EventArgs e)
{
this.PivotGrid1.Model.DataSource.Rows[0].FilterItems.Values = new List<string>() { "United Kingdom" };
this.PivotGrid1.Model.DataSource.Columns[0].FilterItems.Values = new List<string>() { "Bike","Car" };
}
Apply summary types
Allows you to specify the required summary type to be used in summary cells of the pivot grid. “Sum” is the default summary type. Following are the summary types that are supported:
- Sum

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
Creating a simple application with pivot grid and relational data source(server mode)
This section covers the information required to create a simple pivot grid bound to the relational data source.
NOTE
ASP.NET MVC web application contains a service that will transfer the data to server-side, process it, and return it to client-side for control rendering and re-rendering. The service utilized for communication can be either the WCF or WebAPI based on user requirement.
Project initialization
Create a new ASP.NET Empty Web Application by using the Visual Studio IDE and name the project “PivotGridDemo”.
Now, add a Web Form to the empty web application. For adding a Web Form, right-click the project in the solution explorer and select Add > New Item. In the Add New Item window, select Web Form and name it GettingStarted.aspx, and then click Add.
To set an appropriate start page, right-click the “GettingStarted.aspx” in the solution explorer and select “Set As Start Page”.
Now, add the following dependency libraries as references to your web application. To add them to your application, right-click References in the solution explorer and select Add Reference. In the Reference Manager dialog, under Assemblies > Extension, the following Syncfusion libraries will be 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.Web
- Syncfusion.EJ.Export
- Syncfusion.EJ.Pivot
Scripts and CSS initialization
The scripts and style sheets that are required to render the control in a web application are mentioned below in an appropriate order:
- ej.web.all.min.css
- jQuery-3.0.0.min.js
- ej.web.all.min.js
Click here to know more about scripts and style sheets available in online (CDN link).
Scripts and style sheets are referred under the <head> tag in the GettingStarted.aspx page.
<head>
<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>
</head>Control initialization
You can drag and drop the pivot grid control from the toolbox (under Syncfusion BI Web category) or manually define the control as shown in the following code sample of the “GettingStarted.aspx” page.
After placing the control in the web page, add the ‘ScriptManager’ next to it to generate appropriate scripts.
<%@ Register Assembly="Syncfusion.EJ.Pivot, Version=24.2450.3, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" Namespace="Syncfusion.JavaScript.Web" TagPrefix="ej" %>
<html>
……
……
<body>
<form runat="server">
<ej:PivotGrid ID="PivotGrid1" Url="/Relational" runat="server" ClientIDMode="Static"></ej:PivotGrid>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
</form>
</body>
</html>The Url property in the pivot grid control points the service endpoint, where the data is processed and fetched in the form of JSON. The services used in the pivot grid control as endpoint are WCF and WebAPI.
NOTE
The above “GettingStarted.aspx” contains WebAPI URL, which is “/Relational”. If the WCF service is used as an endpoint, then the URL will look like “/RelationalService.svc”.
If you enter the code manually instead of drag and drop from the toolbox, then you need to register the referenced assemblies in the Web.config file.

Adding a WebAPI controller
To add a WebAPI controller in an 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.
Now, the WebAPI controller is added to the application that contains the “RelationalController.cs” file.
NOTE
While adding the WebAPI controller class, add the mandatory suffix ‘Controller’. For example, in this demo, the controller is named “RelationalController”.
Next, remove all the existing methods such as “Get”, “Post”, “Put”, and “Delete” present in the RelationalController.cs file.
namespace PivotGridDemo
{
public class RelationalController: ApiController
{
}
}Adding the list of namespaces
The following are the list of namespaces to be added on top of the main class in the RelationalController.cs file:

}Configure routing in global application class
To add a Global.asax, 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 configure the routing as shown in the following code example:
public class Global: System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
GlobalConfiguration.Configuration.Routes.MapHttpRoute(name: "DefaultApi", routeTemplate: "{controller}/{action}/{id}", defaults: new
{
id = RouteParameter.Optional
});
AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
}
}Now, the pivot grid will be rendered with sales amount over a set of products across different customer geographic locations.
