        <script src="Scripts/bold-reports/"></script>

    To learn more about rendering a report with data visualization report items, refer to the how to render data visualization report items section.

Initialize Report Viewer

Initialize the Report Viewer as shown in the following code sample on the Default.aspx page.

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
    <div style="height: 650px;width: 950px;min-height:404px;">
        <Bold:ReportViewer runat="server" ID="viewer">

Add already created reports

The Report Viewer is only for rendering reports. You must use a report generation tool to create a report. To learn more about creating new reports, refer to the create RDL report section.

  1. Create a folder Resources in your application to store the RDL reports.

  2. Add already created reports to the newly created folder.

    In this tutorial, the sales-order-detail.rdl report is used, and it can be downloaded from here. You can add the reports from the Syncfusion installation location. For more information, refer to the samples and demos section.

Configure Web API

The interface IReportController has a declaration of action methods that are defined in the Web API Controller for processing the RDL, RDLC, and SSRS reports and for handling requests from the Report Viewer control. The IReportController has the following action methods declaration.

Methods Description
PostReportAction Action (HttpPost) method for posting the request in the report process.
OnInitReportOptions Report initialization method occurs when the report is about to be processed.
OnReportLoaded Report loaded method occurs when the report and sub report start loading.
GetResource Action (HttpGet) method to get resources for the report.


The class ReportHelper contains helper methods that help to process a Post or Get request from the Report Viewer control and return the response to the Report Viewer control. It has the following methods:

Methods Description
GetResource Returns the report resource to the requested key.
ProcessReport Processes the report request and returns the result.

Add Web API Controller

  1. Right-click the Controller folder in your project and select Add > New Item from the context menu.

  2. Select Web API Controller Class from the listed templates and name it as ReportViewerController.cs. Provide controller name

  3. Click Add.

    While adding the Web API Controller class, naming it with the suffix Controller that is mandatory.

  4. Open the ReportViewerController and add the following using statement.

    using BoldReports.Web.ReportViewer;
  5. Inherit the IReportController interface, and implement its methods (replace the following code in the newly created Web API controller).

    public class ReportViewerController : ApiController, IReportController
        // Post action for processing the RDL/RDLC report
        public object PostReportAction(Dictionary<string, object> jsonResult)
            return ReportHelper.ProcessReport(jsonResult, this);
        // Get action for getting resources from the report
        public object GetResource(string key, string resourcetype, bool isPrint)
            return ReportHelper.GetResource(key, resourcetype, isPrint);
        // Method that will be called when initialize the report options before start processing the report
        public void OnInitReportOptions(ReportViewerOptions reportOption)
            // You can update report options here
        // Method that will be called when reported is loaded
        public void OnReportLoaded(ReportViewerOptions reportOption)
            // You can update report options here

Add routing information

To configure routing to include an action name in the URI, open the WebApiConfig.cs file and change the routeTemplate in the Register method as follows,

public static class WebApiConfig
    public static void Register(HttpConfiguration config)
        // Web API configuration and services

        // Web API routes

        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}/{id}",
        defaults: new { id = RouteParameter.Optional }

If you are looking to load the report directly from the SQL Server Reporting Services (SSRS), then you can skip the following steps and move to the SSRS Report.

Set report path and service URL

To render the reports available in the application, set the ReportPath and ReportServiceUrl properties of the Report Viewer. You can replace the following code on your Report Viewer page.

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
    <link href="Content/bold-reports/material/bold.reports.all.min.css" rel="stylesheet" />
    <script src="" type="text/javascript"></script>
    <script src="Scripts/bold-reports/common/bold.reports.common.min.js"></script>
    <script src="Scripts/bold-reports/common/bold.reports.widgets.min.js"></script>
    <script src="Scripts/bold-reports/"></script>
    <div style="height: 650px;width: 950px;min-height:404px;">
        <Bold:ReportViewer runat="server" ID="viewer" ReportPath="~/Resources/sales-order-detail.rdl"

The report path property is set for the RDL report that is added to the project Resources folder.
