DependencyObject source = e.OriginalSource as DependencyObject;
if (source == null) return;
DataRecordPresenter drp = Infragistics.Windows.Utilities.GetAncestorFromType(source, typeof(DataRecordPresenter), true) as DataRecordPresenter;
CellValuePresenter cvp = CellValuePresenter.FromRecordAndField(drp.DataRecord, drp.DataRecord.FieldLayout.Fields[0]);
ListBox lstSource = Infragistics.Windows.Utilities.GetDescendantFromName(cvp, "lstWorkUnit") as ListBox;
ListBox lstTarget = Infragistics.Windows.Utilities.GetDescendantFromName(cvp, "lstSelectedUnit") as ListBox;
var a = Infragistics.Windows.Utilities.GetDescendantFromType(cvp, typeof(XamTextEditor), false);
