This page is for data modellers or application developers who want to apply special formatting to data that meets specific criteria.
Overview
A formatting rule allows you to specify an expression which evaluated can apply the selected style to the parent object. It allows to apply styles conditionally, depending on current values displayed on the screen.
A formatting rule can be applied to a stream view attribute or to a layout component. If you apply a formatting rule to a layout template, all layout components created from the template will have a copy of the formatting rule applied.
Basic Settings
For information about the properties toolbar, and about the sections Parent Details, Analysis Models, Description and Audit Summary, see Common Properties. We recommend you always add a Description that explains the purpose of the item you are creating.
For a full list of all the PhixFlow property tabs and windows, see Properties, Windows, Menus and Toolbars.
| Field | Description |
|---|---|
| Rule Expression | Expression to be evaluated on order to determine should the Style be applied. This expression takes PhixFlow Internal Variables including _current, _field, _itemNumber and _this. See examples below. |
| Style | Style to be applied when the Rule Expression evaluates to true. |
| Order | Order of the Rule Expression. |
| Enabled | Flag showing is the Rule Expression enabled. |
| Stop If True | Flag showing if other rules shouldn't be applied if the current Rule applies. |

Using Variables in Expressions
In formatting rules , the _form, _grid and _current act on a specific record. The record depends on the structure of layout components on the dashboard.
| Formatting expression variable | Where | ||||
|---|---|---|---|---|---|
| Stream view directly on a dashboard | form on a dashboard | stream view on a form | form on a card | grid on a card | |
_form acts on the record | na | currently displayed on the form | currently displayed on the form | currently displayed on the card | backing the card |
_grid acts on the record | na | na | na | ||
_current acts on the record | currently displayed in the grid | na | currently displayed in the grid | currently displayed in the card | currently displayed in the grid |
