Object Model

Syntax

[Visual Basic]
Public Class RecordManager 
   Inherits PropertyChangeNotifier

[C#]
public class RecordManager : PropertyChangeNotifier

Remarks

DataRecords are created to represent each item in the DataPresenterBase.DataSource. The DataRecord exposes a read-only DataRecord.DataItem property that returns the associated item from the data source as well as a corresponding DataRecord.DataItemIndex property. These DataRecords are managed by the RecordManager and exposed via its RecordManager.Unsorted, RecordManager.Sorted and RecordManager.Groups collection properties.

The RecordManager is responsible for listening to events raised by the DataPresenterBase.DataSource thru either the INotifyCollectionChanged or the IBindingList interfaces. Based on these notifcations it keeps its RecordManager.Sorted and RecordManager.Unsorted collections of DataRecords in sync and raises corresponding events on each thru their INotifyCollectionChanged interface implemenations.
