Scrolls to the prior page in a DataWindow control.
Description
Scrolls a DataWindow control backward one page, displaying another group of rows in the DataWindow's display area. (A page is the number of rows that can be displayed in the DataWindow control at one time.) ScrollPriorPage changes the current row but not the current column.

integer rtename.ScrollPriorPage ( )

rtename |
The name of the DataWindow control in which you want to scroll to the prior page. The DataWindow object in the DataWindow control must be a RichTextEdit DataWindow. |

You can use the same syntax with any PowerBuilder RichTextEdit control. See the section called “ScrollPriorPage” in PowerScript Reference.

This statement scrolls to the prior page of the RichText document in the DataWindow control dw_rpt. If there are multiple instances of the document, it can scroll to the prior instance:
dw_rpt.ScrollPriorPage()
