The Style Rules Panel

Use the Style Rules panel to define expressions that determine the appearance of features.

The elements in the Style Rules panel are:

1. Rule Editing Tools

   	Delete Selected Rule	Removes the selected rule from the Style Rules Panel. You can re-import it if you need it again.
   	Save Selected Rules	Saves all selected rules to an XML file that you specify. You can import the rules using the Load Rules option.

2. Style Rules — Each row in the list represents a rule. Rules are applied in the order that they appear in the list.
3. Category Tabs — Each tab contains catalogs of style rules for a particular feature class. Because style rules use expressions, and expressions use properties that are specific to a feature class, you must select the tab for the feature class whose rule you are defining or editing.
4. Select All/Deselect All — Use these buttons to select or deselect rules for any operation.
5. Global Rule Tools — Use these tools to affect all rules of all rule types.

   	Import All	Loads rules for all rule types from an XML file that you specify.
   	Commit	Saves changed rules of any rule type to the database.
   	Refresh	Saves changed rules of any rule type to the database and also initiates a regeneration of the model.
