The Rich Text Formatted (RTF) field is used to display a formatted text. When you click this button, a menu appears where you can select other fields that are contained in the same report definition file to be displayed in RTF format. These are data-bound RTF fields.

RTF fields are particularly used in creating Mail Merge reports.

1. Create a new report C1FlexReportDesigner.
2. Bind the report to 'Customers' and 'Orders' Table by giving the following Sql statement:

   Customers.City, Customers.Region, Customers.Country, Customers.PostalCode,
   Orders.OrderID, Orders.OrderDate, [Order Subtotals].Subtotal
   FROM Customers INNER JOIN ([Order Subtotals] INNER JOIN Orders
   ON [Order Subtotals].OrderID = Orders.OrderID)
   ON Customers.CustomerID = Orders.CustomerID
   WHERE CompanyName = "Ernst Handel"
   

3. From the Insert tab add the RTF field.
