DataWindow objects and all entities in them (such as columns, text, graphs, and pictures) each have a set of properties. You can look at and change the values of these properties during execution using DataWindow methods or property expressions. You can also create DataWindow objects during execution.
A DataWindow object that is modified or created during execution is called a dynamic DataWindow object.
About property expressions
Property expressions are available in PowerBuilder and the
Web DataWindow. Property expressions use dot notation to address
properties directly and are evaluated on the server component of
the Web DataWindow.
For the Web ActiveX, property expressions are not available; use the Describe and Modify methods.
Using this dynamic capability, you can allow users to change the appearance of the DataWindow object (for example, change the color and font of the text) or create ad hoc queries by redefining the data source. After you create a dynamic DataWindow object and the user is satisfied with the way it looks and the data that is displayed, the user can print the contents as a report.
