  Hello,
  
  Here is how I do this in the demo:
  

        List<Category> list = new List<Category>();
        Category category = new Category("Beverages", "Soft drinks, coffees, teas, beers");
        category.Products.Add(new Product("Chai", 18m));
        category.Products.Add(new Product("Chang", 19m));
        category.Products.Add(new Product("Ipoh coffee", 46m));
        list.Add(category);
  
        category = new Category("Confections", "Desserts, candies, and sweet breads");
        category.Products.Add(new Product("Chocolade", 12.75m));
        category.Products.Add(new Product("Scottish Longbreads", 12.5m));
        category.Products.Add(new Product("Tarte au sucre", 49.3m));
        list.Add(category);
  
        category = new Category("Seafood", "Seaweed and fish");
        category.Products.Add(new Product("Boston Crab Meat", 18.4m));
        category.Products.Add(new Product("Red caviar", 15m));
        list.Add(category);
  
        FReport.Load(...);
        FReport.RegisterData(list, "Categories BusinessObject", BOConverterFlags.AllowFields, 3);
        FReport.Show();
  
  
  // business objects
      public class Category
      {
        public string Name;
        public string Description;
        public List<Product> Products;
  
        public Category(string name, string description)
        {
          Name = name;
          Description = description;
          Products = new List<Product>();
        }
      }
  
      public class Product
      {
        public string Name;
        public decimal UnitPrice;
  
        public Product(string name, decimal unitPrice)
        {
          Name = name;
          UnitPrice = unitPrice;
        }
      }

  Thanks but this is in code. I want to know how can I do this in Designer.
  For example, when you open Business Objects.frx report in Designer and click Data -> Data Sources you can see the Business Objects DataSource. However if I want to add a DataSource i can only add DB data sources, not lists.

  It can be done in Visual Studio IDE, "Data|Add New Data Source..." menu.
  - create new datasource which is bound to an object in your application;
  - add "BindingSource" component and connect it to your datasource;
  - put the "Report" component on your form, invoke its designer. You will be asked to choose a datasource. Select your BindingSource object.
  
  Note that in design-time, you cannot preview a report, because datasource is empty. This can be done in run-time only. In run-time, you should instantiate your datasource, fill it with data, then run a report.

  I have found solution by myself

  webReport.Report.Load(fileName);
  webReport.Report.Dictionary.RegisterBusinessObject(businessObjects, "BO", 10, true);
  webReport.Report.Save(fileName)
  

  And then I can open saved *.frx file in designer.
  Maybe someone can suggest better solution

  Hi,
  
  I am evaluating Fast Reports for .net.
  
  I have visual studio 2013. I am having trouble doing this step "add BindingSource component and connect it to your datasource;" can you make an example?
  
  Thanks.
