Visual BasicCopy Code
Private Sub rptUnbound_DataInitialize(ByVal sender As Object, ByVal e As _
    System.EventArgs) Handles MyBase.DataInitialize
    Fields.Add("CategoryName")
    Fields.Add("ProductName")
    Fields.Add("UnitsInStock")
    Fields.Add("Description")
End Sub

Remarks

ActiveReports initializes the collection with all the fields in the DataSource if any.  You can add custom unbound fields to the collection in the DataInitialize event.  This allows you to create custom calculated fields and bind the report sections and controls to fields not available through the data source but provided at run time in the FetchData event.   This allows the report to bind to collections, arrays or any other custom data structure that your application handles.

Note:  Do not reference the Fields collection outside the DataInitialize and FetchData events.
