Supporting Cross-Datasource Relations

The .NET DataProvider concept allows to bind to almost any data source. Basically, it mimics a relational database management system containing tables, relations, sort orders etc. However, often you'll find yourself needing to combine data from different sources, e.g. a server log file that contains customer logins and a SQL customer database that contains all pertinent information about the customers.

WPF Wrapper for PreviewControl

Version 22 of List & Label will introduce a new WPF wrapper control for the existing WinForms PreviewControl. While it uses a Windows­Forms­Host at the core, the wrapper is a drag & drop replacement for the existing WPF preview control which will continue to be supported.

In addition, the current Delphi data-binding engine still works against the BDE, a technology that has been deprecated quite a while ago by Embarcadero.
