Render RDLC report

The data binding support, allows you to view RDLC reports that exist on the local file system with JSON array and custom business object data collection. The following steps demonstrates how to render a RDLC report with JSON array and custom business object data collection.

Add the RDLC report product-list.rdlc from Bold Reports installation location to your application Resources folder. For more information, see Samples and demos.

Bind data source at client side

1. Set the RDLC report path to the ReportPath property.

2. Assign the ProcessingMode property to ProcessingMode.Local.

3. Bind the data from viewdata collection to the DataSources property as shown in following code.

   @(Html.Bold().ReportViewer("viewer")
       .ProcessingMode(BoldReports.ReportViewerEnums.ProcessingMode.Local)
       .ReportPath("~/Resources/product-list.rdlc")
       .ReportServiceUrl("/api/ReportViewer")
       .DataSources(ds => ds.Name("list").Value(ViewData["DataSource"]).Add())
   )

4. Create a class and methods that returns business object data collection. Use the following code in your application Web API Service.

   public partial class HomeController : Controller
   {
       public ActionResult Index()
       {
           ProductList productList = new ProductList();
           ViewData["DataSource"] = productList.GetData();
           return View();
       }
   }
   
   public class ProductList
   {
       public string ProductName { get; set; }
       public string OrderId { get; set; }
       public double Price { get; set; }
       public string Category { get; set; }
       public string Ingredients { get; set; }
       public string ProductImage { get; set; }
   
       public IList GetData()
       {
           List<ProductList> dataList = new List<ProductList>();
           ProductList data = null;
           data = new ProductList() {ProductName = "Baked Chicken and Cheese",OrderId = "323B60",Price = 55,Category = "Non-Veg",Ingredients = "grilled chicken, corn and olives.",ProductImage = "" };
           dataList.Add(data);
           data = new ProductList() {ProductName = "Chicken Delite",OrderId = "323B61",Price = 100,Category = "Non-Veg",Ingredients = "cheese, chicken chunks, onions & pineapple chunks.",ProductImage = ""};
           dataList.Add(data);
           data = new ProductList() {ProductName = "Chicken Tikka",OrderId = "323B62",Price = 64,Category = "Non-Veg",Ingredients = "onions, grilled chicken, chicken salami & tomatoes.",ProductImage = ""};
           dataList.Add(data);
           return dataList;
       }
   }

Bind data source in Web API controller

The following steps help you to configure the Web API to render the RDLC report with business object data collection.

• Create a class and methods that returns business object data collection. Use the following code in your application Web API Service.

  public class ProductList
  {
      public string ProductName { get; set; }
      public string OrderId { get; set; }
      public double Price { get; set; }
      public string Category { get; set; }
      public string Ingredients { get; set; }
      public string ProductImage { get; set; }
  
      public static IList GetData()
      {
          List<ProductList> dataList = new List<ProductList>();
          ProductList data = null;
          data = new ProductList() {ProductName = "Baked Chicken and Cheese",OrderId = "323B60",Price = 55,Category = "Non-Veg",Ingredients = "grilled chicken, corn and olives.",ProductImage = "" };
          dataList.Add(data);
          data = new ProductList() {ProductName = "Chicken Delite",OrderId = "323B61",Price = 100,Category = "Non-Veg",Ingredients = "cheese, chicken chunks, onions & pineapple chunks.",ProductImage = ""};
          dataList.Add(data);
          data = new ProductList() {ProductName = "Chicken Tikka",OrderId = "323B62",Price = 64,Category = "Non-Veg",Ingredients = "onions, grilled chicken, chicken salami & tomatoes.",ProductImage = ""};
          dataList.Add(data);
          return dataList;
      }
  }

• Set the ProcessingMode to ProcessingMode.Local and ReportPath to the RDLC report location.

• Bind the business object data values collection by adding new item to the DataSources as in the following code snippet.

  [NonAction]
  public void OnInitReportOptions(ReportViewerOptions reportOption)
  {
      reportOption.ReportModel.ProcessingMode = ProcessingMode.Local;
      reportOption.ReportModel.ReportPath = System.Web.Hosting.HostingEnvironment.MapPath(@"~/Resources/product-list.rdlc");
      reportOption.ReportModel.DataSources.Add(new BoldReports.Web.ReportDataSource { Name = "list", Value = ProductList.GetData() });
  }

  Here the Name is case sensitive and it should be same as in the data source name in the report definition. The Value accepts IList, DataSet, and DataTable inputs.

Load report as stream

To load report as a stream, create a report stream using the FileStream class and assign the report stream to the Stream property.

[NonAction]
public void OnInitReportOptions(ReportViewerOptions reportOption)
{
    // Opens the report from application Resources folder using FileStream
    FileStream reportStream = new FileStream(System.Web.Hosting.HostingEnvironment.MapPath(@"~/Resources/product-list.rdlc"), FileMode.Open, FileAccess.Read);
    reportOption.ReportModel.Stream = reportStream;
    reportOption.ReportModel.ProcessingMode = ProcessingMode.Local;
    reportOption.ReportModel.DataSources.Add(new BoldReports.Web.ReportDataSource { Name = "list", Value = ProductList.GetData() });
}

In the above code, product-list.rdlc report is loaded from the Resources folder location.
