Class ReportsControllerBase

Base API controller for exposing a WebAPI to the report engine.

Inheritance
System.Object
ReportsControllerBase
ReportDesignerControllerBase
Namespace: Telerik.Reporting.Services.WebApi
Assembly: Telerik.Reporting.Services.WebApi.dll

Syntax

[ReportsExceptionFilter]
public abstract class ReportsControllerBase : ApiController
Remarks

A call to the RegisterRoutes(HttpConfiguration) method must be added to the WebApiConfig.Register method so that the controller actions are accessible from the routing mechanisms of the ASP.Net WebAPI framework.

Constructors

ReportsControllerBase()

Initializes a new instance of the ReportsControllerBase class.

Declaration
protected ReportsControllerBase()

Properties

ReportServiceConfiguration

Gets or sets the configuration of the report service.

Declaration
public IReportServiceConfiguration ReportServiceConfiguration { get; set; }
Property Value
IReportServiceConfiguration

Remarks

When inheriting the ReportsControllerBase controller basic configuration is needed. Provide an object implementing the IReportServiceConfiguration in order to configure the report service. This should be done in the controllers' constructor using static object to preserve the configuration between requests or using dependency injection.

Examples

This example shows how to configure WebAPI service using dependency injection.

  1. Setup method registering the configuration object in a dependency injection container. The example uses the Unity container. 
    using System.Web;
using Telerik.Reporting.Services;

public static class WebApiConfig
{
    public static void RegisterDependencies(System.Web.Http.HttpConfiguration config)
    {
        var container = new Microsoft.Practices.Unity.UnityContainer();

        container.RegisterInstance(
            typeof(Telerik.Reporting.Services.IReportServiceConfiguration),
            null,
            CreateReportServiceConfiguration(),
            new Microsoft.Practices.Unity.ContainerControlledLifetimeManager());

        config.DependencyResolver = new UnityResolver(container);
    }

    static IReportServiceConfiguration CreateReportServiceConfiguration()
    {
        var resolver = new UriReportSourceResolver(HttpContext.Current.Server.MapPath("~/Reports"))
            .AddFallbackResolver(new TypeReportSourceResolver());

        return new ReportServiceConfiguration
        {
            HostAppId = "Application1",
            ReportSourceResolver = resolver,
            Storage = new Telerik.Reporting.Cache.File.FileStorage(),
            // Storage = new Telerik.Reporting.Cache.StackExchangeRedis.RedisStorage(StackExchange.Redis.ConnectionMultiplexer.Connect("localhost:10001")),
            // Storage = new Telerik.Reporting.Cache.MsSqlServerStorage(@"Data Source=(local)\SQLEXPRESS;Initial Catalog=RSStorage;Integrated Security=SSPI"),
        };
    }
}

    Public NotInheritable Class WebApiConfig
    Private Sub New()
    End Sub
    Public Shared Sub RegisterDependencies(config As System.Web.Http.HttpConfiguration)
        Dim container = New Microsoft.Practices.Unity.UnityContainer()

        container.RegisterInstance(
            GetType(IReportServiceConfiguration),
            Nothing,
            CreateReportServiceConfiguration(),
            New Microsoft.Practices.Unity.ContainerControlledLifetimeManager())

        config.DependencyResolver = New UnityResolver(container)
    End Sub

    Private Shared Function CreateReportServiceConfiguration() As IReportServiceConfiguration
        Dim resolver = New UriReportSourceResolver(
                        HttpContext.Current.Server.MapPath("~/Reports")) _
                        .AddFallbackResolver(New TypeReportSourceResolver())

        Dim reportServiceConfiguration As New ReportServiceConfiguration()
        reportServiceConfiguration.HostAppId = "Application1"
        reportServiceConfiguration.ReportSourceResolver = resolver
        reportServiceConfiguration.Storage = New Telerik.Reporting.Cache.File.FileStorage()
        'reportServiceConfiguration.Storage = New Telerik.Reporting.Cache.StackExchangeRedis.RedisStorage(StackExchange.Redis.ConnectionMultiplexer.Connect("localhost:10001"))
        'reportServiceConfiguration.Storage = New Telerik.Reporting.Cache.MSSqlServerStorage("Data Source=(local)\SQLEXPRESS;Initial Catalog=RSStorage;Integrated Security=SSPI")

        Return reportServiceConfiguration
    End Function
End Class
    Example based on the article Dependency Injection in ASP.NET Web API 2
  2. ReportsController implementation 
    public class ReportsController : Telerik.Reporting.Services.WebApi.ReportsControllerBase
{
    public ReportsController(ReportServiceConfiguration configuration)
    {
        this.ReportServiceConfiguration = configuration;
    }
}

    Public Class ReportsController
    Inherits WebApi.ReportsControllerBase
    Public Sub New(configuration As ReportServiceConfiguration)
        Me.ReportServiceConfiguration = configuration
    End Sub
End Class
  3. Invoke the setup in the Application_Start method. 
    public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        WebApiConfig.RegisterDependencies(System.Web.Http.GlobalConfiguration.Configuration);
        //...
    }
}

    Public Class MvcApplication
    Inherits System.Web.HttpApplication
    Protected Sub Application_Start()
        WebApiConfig.RegisterDependencies(System.Web.Http.GlobalConfiguration.Configuration)
        '...
    End Sub
