The event data class exposes the following methods:

Method Description

IsFilteredBy(String) Gets whether the GridControl is filtered by the field name.
IsGroupedBy(String) Gets whether the GridControl is grouped by the field name.
IsSortedBy(String) Gets whether the GridControl is sorted by the field name.
