  I noticed also this :

  public class Test1
  {
      public string TestField1 { get; set;}
  }
  
  public class Test2 : Test1
  {
      public string TestField2 { get; set;} 
  }
  
  //in my FastReport code
  List<Test2> testList = new List<Test2>();
  // .... add objects ....
  
  report.RegisterData(testList,"Test");
  report.GetDataSource("Test").Enabled=true;
  
  //... later in TextObject t
  t.Text = "[Test.TestField2]";
  

  
  report.Prepare() throws the error "The name 'Test' does not exist in the current context"

  Hello,
  
  Did you register the data source in a report using the report.RegisterData call? Please look at the demos to see how to do this:
  Demos\C#\DataFromBusinessObject
  Demos\C#\Main

  Yes I did that... but.... [img]style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> Here is my class hierarchy : I have a base class (for example Base) with some public properties. I inherit from Base class into class Derived in which I have other public properties. My Data Source is a List<Derived> generic list, which I register and I still get the same error. But if Derived does not inherit from Base it works properly. The code example I gave earlier explains it.[/img]

  Could you make a simple demo for me and send it to tz@fast-report.com? Your code example is close to what we have in the demo, which is working fine.

  I found what the problem was.
  FastReport interprets differently between IEnumerable types. I used generic list of objects ( List<T> ).
  I tried it with ArrayList and it works.
  Thanks anyway

  Hello,
  
  The problem is that you are using List<TestClass>, which contains TestClass2 instances. Either use List<TestClass2>, or ArrayList.
