Creating a simple application with pivot chart and OLAP data source (server mode)
This section covers the information required to create a simple pivot chart bound to OLAP data source.
NOTE
ASP.NET empty 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 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 “PivotChartDemo”.
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 Default.aspx, and then click Add.
Add the following dependency libraries as references to your empty 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.

</body>
</html>The “Url” property in pivot chart control points the service endpoint, where the data is processed and fetched in the form of JSON. The services used in the pivot chart control as endpoint are WCF and WebAPI.
NOTE
The above “Default.aspx” contains WebAPI URL, which is “/Olap”. If WCF service is used as endpoint, the URL will look like “/OlapService.svc”.
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 “OlapController.cs”, and then click Add.
Now, 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 following sections.
- OlapController.cs
NOTE
While adding the WebAPI controller class, add the mandatory suffix “Controller”. For example, in the demo, the controller is named as “OlapController”.
Next, remove all existing methods such as “Get”, “Post”, “Put”, and “Delete” present in the OlapController.cs file.
namespace PivotChartDemo
{
public class OlapController : ApiController
{
}
}List of namespaces
Following are the list of namespaces to be added on top of the main class in the OlapController.cs file:
using Syncfusion.Olap.Manager;
using Syncfusion.Olap.Reports;
using Syncfusion.JavaScript;
namespace PivotChartDemo
{
public class OlapController : ApiController
{
}
}Data source initialization
Now, the connection string to connect OLAP cube and pivot chart instances is created immediately in the main class of the OlapController.cs file.
namespace PivotChartDemo
{
public class OlapController : ApiController
{
string connectionString = "Data Source=https://bi.syncfusion.com/olap/msmdpump.dll; Initial Catalog=Adventure Works DW 2008 SE;";
PivotChart htmlHelper = new PivotChart();
//Other codes
}
}Service methods in WebAPI controller
Now, you can define the service methods in the OlapController class, find in the OlapController.cs file which was created while adding the WebAPI controller class to your web application.
namespace PivotChartDemo
{
public class OlapController : ApiController
{
string connectionString = "Data Source=https://bi.syncfusion.com/olap/msmdpump.dll; Initial Catalog=Adventure Works DW 2008 SE;";
PivotChart htmlHelper = new PivotChart();
[System.Web.Http.ActionName("InitializeChart")]
[System.Web.Http.HttpPost]
public Dictionary<string, object> InitializeChart(Dictionary<string, object> jsonResult)
{
OlapDataManager DataManager = null;
DataManager = new OlapDataManager(connectionString);
DataManager.SetCurrentReport(CreateOlapReport());
return htmlHelper.GetJsonData(jsonResult["action"].ToString(), DataManager);
}
[System.Web.Http.ActionName("DrillChart")]
[System.Web.Http.HttpPost]
public Dictionary<string, object> DrillChart(Dictionary<string, object> jsonResult)
{
OlapDataManager DataManager = new OlapDataManager(connectionString);
DataManager.SetCurrentReport(Syncfusion.JavaScript.Olap.Utils.DeserializeOlapReport(jsonResult["olapReport"].ToString()));
return htmlHelper.GetJsonData(jsonResult["action"].ToString(), DataManager, jsonResult["drilledSeries"].ToString());
}
private OlapReport CreateOlapReport()
{
OlapReport olapReport = new OlapReport();
olapReport.Name = "Default Report";
olapReport.CurrentCubeName = "Adventure Works";
DimensionElement dimensionElementColumn = new DimensionElement();
//Specifying the Name for the Dimension Element
dimensionElementColumn.Name = "Customer";
dimensionElementColumn.AddLevel("Customer Geography", "Country");
MeasureElements measureElementColumn = new MeasureElements();
//Specifying the Name for the Measure Element
measureElementColumn.Elements.Add(new MeasureElement { Name = "Customer Count" });
DimensionElement dimensionElementRow = new DimensionElement();
//Specifying the Dimension Name
dimensionElementRow.Name = "Date";
dimensionElementRow.AddLevel("Fiscal", "Fiscal Year");
///Adding Row Members
olapReport.SeriesElements.Add(dimensionElementRow);
///Adding Column Members
olapReport.CategoricalElements.Add(dimensionElementColumn);
///Adding Measure Element
olapReport.CategoricalElements.Add(measureElementColumn);
return olapReport;
}
}
}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, delete all methods in the Global class and 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 chart is rendered with customer count over a period of fiscal years across different customer geographic locations.
WCF
This section demonstrates the utilization of WCF service as endpoint binding the OLAP data source to a simple pivot chart. For more details on this topic, click here.
