Sorting Customization Rule

Sorting rules provide a way to either disable sorting or sort instances my specific properties. There are 2 types of sorting rules for both of these scenarios.

Property Sorting Rule

Rule to configure sorting for certain ECInstances in the hierarchy and/or content. It is possible to configure different sorting for different types of ECInstances.

Multiple sorting rules may be applied for the same instances - in this case the instances are first sorted by the highest priority rule and then the lower priority ones.

Note: This rule is not meant to be used to sort grouping nodes, custom nodes or other non ECInstance type of nodes.

Attributes

Name Required? Type Default Meaning
Filtering
priority No number 1000 Defines the order in which presentation rules are evaluated.
onlyIfNotHandled No boolean false Should this rule be ignored if there is already an existing rule with a higher priority.
condition No ECExpression "" Defines a condition for the rule, which needs to be met in order to execute it.
class No SingleSchemaClassSpecification All classes in current context Specification of ECClass whose ECInstances should be sorted.
isPolymorphic No boolean false Should class defined in this rule be handled polymorphically.
Sorting
propertyName Yes string Name of the property which should be used for sorting.
sortAscending No boolean true Should instances be sorted in ascending order.

  "class": { "schemaName": "MySchema", "className": "MyClass" },
  "isPolymorphic": true
}

Disabled Sorting Rule

Rule to disable sorting for certain ECInstances in the hierarchy and/or content.
