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 Unsorted, Sorted and Groups collection properties.

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