ScrollNextPage

Scrolls to the next page in a DataWindow.

To scroll

Use

To the next group of rows in a DataWindow (when the DataWindow does not have the RichTextEdit presentation style)

Syntax 1

A RichTextEdit DataWindow to view the next page within the document (PowerBuilder only)

Syntax 2


Syntax 1 For DataWindow controls and child DataWindows

Description

Scrolls a DataWindow control forward one page, displaying the next 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.) ScrollNextPage changes the current row, but not the current column.

Applies to

DataWindow type

Method applies to

PowerBuilder

DataWindow control, DataWindowChild object


Syntax

PowerBuilder

long dwcontrol.ScrollNextPage ( )

Argument

Description

dwcontrol

A reference to a DataWindow control or child DataWindow


Return value

Returns the number of the row displayed at the top of the DataWindow control when the scroll finishes or tries to scroll past the last row. ScrollNextPage returns 1 with nested or composite reports and child DataWindows since, in these cases, the current row cannot be changed. ScrollNextPage returns -1 if an error occurs.

If dwcontrol is null, in PowerBuilder and JavaScript the method returns null.

Usage

ScrollNextPage does not highlight the current row. Use SelectRow to let the user know what row is current.

For an example that uses RowCount and Describe to check whether the user has scrolled to the last page, see RowCount.

Events

ScrollNextPage can trigger these events:

ItemChanged
ItemError
ItemFocusChanged
RowFocusChanged
RowFocusChanging

Examples

This statement scrolls dw_employee forward one page:

dw_employee.ScrollNextPage()

Syntax 2 For RichTextEdit DataWindows

Description

Scrolls to the next page of the document in a RichTextEdit DataWindow.

Applies to

DataWindow type

Method applies to

PowerBuilder

DataWindow control


Syntax

PowerBuilder

integer rtedwname.ScrollNextPage ( )

Argument

Description

rtedwname

A reference to a DataWindow control. The DataWindow object in the DataWindow control must be a RichTextEdit DataWindow.


Return value

Returns 1 if it succeeds and -1 if an error occurs. If rtedwname is null, in PowerBuilder and JavaScript the method returns null.

Usage

A RichText DataWindow contains multiple instances of the document, one instance for each row. When the last page of the document for one row is visible, calling ScrollNextPage advances to the first page for the next row.

PowerBuilder RichTextEdit control

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

Examples

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

dw_rpt.ScrollNextPage()
