Remarks

Deleting DataRecords is supported for DataSources that implement the System.ComponentModel.IBindingList interface and return true from its System.ComponentModel.IBindingList.AllowRemove property. It is also supported for DataSources that only implement the System.Collections.IList interface and return false from both its System.Collections.IList.IsReadOnly and System.Collections.IList.IsFixedSize properties.

Assuming deleting of DataRecords is enabled then when the user selects one or more DataRecords and presses the Delete key the RecordsDeleting and RecordsDeleted events will be raised. DataRecords can also be deleted programmatically by first selecting them (via the Record.IsSelected property or the SelectedItems collection) and then calling ExecuteCommand(RoutedCommand) with the DataPresenterCommands.DeleteSelectedDataRecords command.

Note: Deleting records is enabled by default. To disable deleting records set the FieldLayoutSettings's FieldLayoutSettings.AllowDelete property to false.
