Glossary Item Box

In ActiveReports Professional Edition, you can set up a custom end-user report designer on a Windows form. When designing a report in the end-user report designer, you can add a section or an ActiveReports control to a report, remove it from a report and modify the properties of the ActiveReports report, section and control classes in code-behind, thus making the changes undoable. This means that you can undo at run time any modification you have made to an ActiveReports report, section or control property in code-behind.
