This example shows how to creating report with Business Objects collection. Business Objects - an object class data with which the data can be presented in different structures: tables, lists, arrays, etc. This example uses two variants of Business Objects - IEnumerable and ITypedList:

private void btPreviewIEnumerable_Click(object sender, System.EventArgs e){
	StiReport report = new StiReport();
	report.RegData("EmployeeIEnumerable", CreateBusinessObjectsIEnumerable.GetEmployees());
	report.Load("..\\BusinessObjects_IEnumerable.mrt");
	report.Show();
}

private void btPreviewITypedList_Click(object sender, System.EventArgs e)
{
	StiReport report = new StiReport();
	report.RegData("EmployeeITypedList", CreateBusinessObjectsITypedList.GetEmployees());
	report.Load("..\\BusinessObjects_ITypedList.mrt");
	report.Show();
}

As IEnumerable object the EmployeeIEnumerable model is used, to populate data the GetEmployees() method of the CreateBusinessObjectsIEnumerable class is used:

public static EmployeeIEnumerableCollection GetEmployees()
{
	EmployeeIEnumerableCollection employees = new EmployeeIEnumerableCollection();
	Company company = new Company("Company1");
	Department storeDepartment = new Department(company, "Store Department");
	Department salesDepartment = new Department(company, "Sales Department");
	
	EmployeeIEnumerable emp = new EmployeeIEnumerable(storeDepartment, "Nicholas", "Nicholas@company1.com");
	emp.Phones.Add(new Phone("(206) 555-9857"));
	emp.Phones.Add(new Phone("(206) 555-6546"));
	emp.Phones.Add(new Phone("(206) 555-7651"));
	employees.Add(emp);
	
	emp = new EmployeeIEnumerable(storeDepartment, "Margaret", "Margaret@company1.com");
	emp.Phones.Add(new Phone("(206) 555-4546"));
	emp.Phones.Add(new Phone("(206) 555-0110"));
	employees.Add(emp);
	
	emp = new EmployeeIEnumerable(storeDepartment, "Janet", "Janet@company1.com");
	emp.Phones.Add(new Phone("(206) 555-5462"));
	emp.Phones.Add(new Phone("(206) 555-8400"));
	emp.Phones.Add(new Phone("(206) 555-9842"));
	employees.Add(emp);
	
	emp = new EmployeeIEnumerable(salesDepartment, "Laura", "Laura@company1.com");
	emp.Phones.Add(new Phone("(206) 555-0022"));
	employees.Add(emp);
	
	emp = new EmployeeIEnumerable(salesDepartment, "Mark", "Mark@company1.com");
	emp.Phones.Add(new Phone("(206) 555-9980"));
	emp.Phones.Add(new Phone("(206) 555-5567"));
	employees.Add(emp);
	
	emp = new EmployeeIEnumerable(salesDepartment, "Michael", "Michael@company1.com");
	emp.Phones.Add(new Phone("(206) 555-5642"));
	employees.Add(emp);
	
	emp = new EmployeeIEnumerable(salesDepartment, "Thomas", "Thomas@company1.com");
	emp.Phones.Add(new Phone("(206) 555-8949"));
	employees.Add(emp);
	
	return employees;
}

As ITypedList object the EmployeeITypedList model is used, to populate data the GetEmployees() method of the CreateBusinessObjectsITypedList class is used:

public static EmployeeITypedListCollection GetEmployees()
{
	EmployeeITypedListCollection employees = new EmployeeITypedListCollection();
	Company company = new Company("Company1");
	Department storeDepartment = new Department(company, "Store Department");
	Department salesDepartment = new Department(company, "Sales Department");
	
	EmployeeITypedList emp = new EmployeeITypedList(storeDepartment, "Nicholas", "Nicholas@company1.com");
	emp.Phones.Add(new Phone("(206) 555-9857"));
	emp.Phones.Add(new Phone("(206) 555-6546"));
	emp.Phones.Add(new Phone("(206) 555-7651"));
	employees.Add(emp);
	
	emp = new EmployeeITypedList(storeDepartment, "Margaret", "Margaret@company1.com");
	emp.Phones.Add(new Phone("(206) 555-4546"));
	emp.Phones.Add(new Phone("(206) 555-0110"));
	employees.Add(emp);
	
	emp = new EmployeeITypedList(storeDepartment, "Janet", "Janet@company1.com");
	emp.Phones.Add(new Phone("(206) 555-5462"));
	emp.Phones.Add(new Phone("(206) 555-8400"));
	emp.Phones.Add(new Phone("(206) 555-9842"));
	employees.Add(emp);
	
	emp = new EmployeeITypedList(salesDepartment, "Laura", "Laura@company1.com");
	emp.Phones.Add(new Phone("(206) 555-0022"));
	employees.Add(emp);
	
	emp = new EmployeeITypedList(salesDepartment, "Mark", "Mark@company1.com");
	emp.Phones.Add(new Phone("(206) 555-9980"));
	emp.Phones.Add(new Phone("(206) 555-5567"));
	employees.Add(emp);
	
	emp = new EmployeeITypedList(salesDepartment, "Michael", "Michael@company1.com");
	emp.Phones.Add(new Phone("(206) 555-5642"));
	employees.Add(emp);
	
	emp = new EmployeeITypedList(salesDepartment, "Thomas", "Thomas@company1.com");
	emp.Phones.Add(new Phone("(206) 555-8949"));
	employees.Add(emp);
	return employees;
}
