'Declaration Public Class RecordFilterCollection Inherits System.Collections.ObjectModel.ObservableCollection(Of RecordFilter)
public class RecordFilterCollection : System.Collections.ObjectModel.ObservableCollection<RecordFilter>
To specify record filters, use the FieldLayout's FieldLayout.RecordFilters or the RecordManager's RecordManager.RecordFilters depending on the FieldLayoutSettings.RecordFilterScope property setting. For the root records, FieldLayout's RecordFilters are used. For child records, by default the RecordManager's RecordFilters are used unless RecordFilterScope is set to AllRecords, in which case the FieldLayout's RecordFilters are used.
To enable the filtering UI, set the FieldSettings.AllowRecordFiltering and FieldLayoutSettings.FilterUIType properties. With the UI enabled, when the user enters filter criteria through the UI, the underlying RecordFilterCollection will be modified to reflect the entered filter criteria.
