layout property to HorizontalLayout.
The HorizontalList control displays a horizontal list of items. If there are more items than can be displayed at once, it can display a horizontal scroll bar so the user can access all items in the list.
The HorizontalList control has the following default sizing characteristics:
| Characteristic | Description |
|---|---|
| Default size | Four columns, with size determined by the cell dimensions. |
| Minimum size | 0 pixels. |
| Maximum size | 5000 by 5000. |
