Selecting and working with portals
You can resize, edit, and delete portals in Layout mode.
To select a portal:
 •
With the arrow pointer, click the border of the portal, or any other area within the portal that doesn't contain a field or object.
See Selecting objects.
To resize a portal row:
1.
Select the portal by clicking the border of the portal, or any other area within the portal that doesn't contain a field or object.
You see selection handles at each corner of the first portal row.
2.
Drag a selection handle.
The first row resizes and each additional row resizes to match the first row.
3.
If necessary, resize the field objects and any other objects that appear within the portal.
To change the record options or display options for a portal:
 •
Double-click the portal. In the Portal Setup dialog box, change options as described above, then click OK.
To delete a portal and its contents:
 •
With the arrow pointer, select the portal, then press Backspace or Delete, or choose Edit menu > Clear.
Notes
 •
In Layout mode, a portal object displays its characteristics in the lower left corner of the object: its table name, the range of rows that the portal will display, a plus sign (+) if vertical scrolling is enabled, Filter if filtering is enabled, and Sort if sorting is enabled.
 •
Filtering records is performed before sorting records.
 •
Filtering records is intended for display purposes only, not for security purposes. Filtering records has no effect on the results of calculations, summaries, and find requests.
 •
In most cases, you should enable Show vertical scroll bar in the Portal Setup dialog box. If you don't and there are more related records than will fit in the number of portal rows you've defined, you won't be able to see all the related records or enter new related records.
 •
You can place more fields into a portal after you have created it. See Setting up a field to display a pop-up menu, checkbox set, or other control.
 •
You can display objects other than fields in the first row of a portal. An object placed in the first row of a portal is displayed once for each related record.
 •
When you add a portal to a layout, its format is based on the theme applied to the layout. You can apply a custom style to change the display attributes of the portal. See Creating new layout object, part, or background styles.
 •
You can’t place a tab control or a web viewer in a portal. If you place these objects in a portal, they appear as objects on the layout that overlap the portal.
 •
You can place a popover button in a portal as long as the associated popover does not contain a tab control, a slide control, a chart, a web viewer, or a portal.
 •
You can place portals in any layout part, but a portal cannot contain another portal. If you place a portal in a portal, the portals overlap.
 •
To number the rows in a portal, in Layout mode, click in the first portal row where you want numbers to display, then choose Insert menu > Record Number Symbol. Numbers appear in portal rows in Browse and Preview modes, and when you print the layout. See Inserting the date, page number, or other variable onto a layout.
 •
You can summarize data that appears in a portal. For example, if you have a portal that displays products and prices, you may want a field that displays a subtotal of all the prices listed in the portal. See Summarizing data in portals.
 •
If one or more records cannot be changed because they are being accessed elsewhere — either in another window by the same user or (if the file is shared) by other clients, then the record(s) is locked.
