now taking this as an input i wanted the output to be formated with a Hierarchical data when parent is all means it is the topmost level kumar fes All. what i need to do here is i need to create an object[0] and then check in list whether kumar exists as a parent in the list if it exista then add those items as under the object[0] as a parent

i need  to create one more oject under
**manju      fes         kumar

anu         frank       kumar**

if you see this class file its shows how data is formatted. public class SampleProjectData { public static ObservableCollection GetSampleData() { DateTime dtS = DateTime.Now;

            ObservableCollection<Product> teams = new ObservableCollection<Product>();
            teams.Add(new Product() { PDName = "Product1", OverallStartTime = dtS, OverallEndTime = dtS + TimeSpan.FromDays(3),  });


            Project emp = new Project() { PName = "Project1", OverallStartTime = dtS + TimeSpan.FromDays(1), OverallEndTime = dtS + TimeSpan.FromDays(6)  };
            emp.Tasks.Add(new Task() { StartTime = dtS, EndTime = dtS + TimeSpan.FromDays(2), TaskName = "John's Task 3" });
            emp.Tasks.Add(new Task() { StartTime = dtS + TimeSpan.FromDays(3), EndTime = dtS + TimeSpan.FromDays(4), TaskName = "John's Task 2" });
            teams[0].Projects.Add(emp);
}
return teams;
}
