  Hello,
  
  FastReport supports business objects. See the demo: Demos\C#\DataFromBusinessObject

  Could you please explain how can I add Business Object to report dataSource ??
  
  For example, the sample "DataFromBusinessObject" shows in the DataWindow "Categories" which is defined in the winforms project.
  
  I need to do the same as I have a "Customers" collection defined in my DAL project that I need to show in the DataWindow EXACTLY as the sample shows "Categories". How to do that in VS/FatsReport designers ???

  Hello,
  
  The easiest way to create a new report with BO is to use run-time designer, just like in this demo.
  1) add a button/menu item in your app ("design a report");
  2) write the following event handler for this button:
  

        // create report instance
        Report report = new Report();
  
        // register the business object
        report.RegisterData(Your_Business_Object, "name_of_BO");
  
        // design the report
        report.Design();
  
        // free resources used by report
        report.Dispose();
  

  
  3) run your app and press the button. Design a report and save it to a file.
  4) to run the report, use the following code:
  

        // create report instance
        Report report = new Report();
  
        // load the existing report
        report.Load("your_report.frx");
  
        // register the business object the same way as when you design a report
        report.RegisterData(Your_Business_Object, "name_of_BO");
  
        // run the report
        report.Show();
  
        // free resources used by report
        report.Dispose();
  

  
  In this way, you work with "live" data when designing a report and when previewing it. Later you may remove the "design a report" button from your app, or you may decide to keep this functionality (as it is royalty-free) - it will allow you to create/modify reports without need to recompile your app. This approach was used in the main demo program to create all demo reports.

  Hello,
  
  I think there are missing understand
  Let's ask in another way
  
  In FastRepoet Demo "DataFromBusinessObject "
  How could you add the "Categories" object (that designed in Form Class) to the FastRepoet Datasource in design Time (to enable me design my report in design Time) ??

  Use BindingSource component. But you will work with no data while designing a report. Why don't you like the solution described in my previous post?
