метод Modified к stringControl

[Poleax]

в методе RUN класса я генерируется форма с гридом. в родителе формы я положил источник , связанный с временной таблицей, которая запоняется в RUN класса.

Вопрос:
Как к stringControl с именем "NameCtrl" добавить метод modified и по значению поля "NameCtrl" (выпадающий список, выбор пользователя) присвоить значение полю comboBoxControl с именем "TitleCtrl" ?

вот код

void run()
{
    Form            form = new Form(formStr(InventJournalPrint_RU));
    List            reportList = List::create(inventJournalReportPackable.packReportList());
    ListIterator    it = new ListIterator(reportList);
    DictEnum        dictEnum = new DictEnum(enumNum(InventJournalReportType_RU));

    FormBuildDataSource         formBuildDataSource;
    FormDataSource              formDataSource;
    InventJournalReport_RU      report;
    FormBuildTabControl         tabControl;
    FormBuildTabPageControl     pageControl;
    FormBuildGridControl        gridControl;
    FormBuildGroupControl       groupControl;
    FormBuildStringControl      stringControl;
    FormBuildComboBoxControl    comboBoxControl;
  
    FormBuildRealControl        realControl;
  
    Args                        args;
    FormRun                     formRun;
    QueryBuildDataSource        qbds;
    Str                         dsName;

    #define.DataGroupName("NamePosition");

    if (reportList.empty())
        return;

    control2Class = new Map(Types::Integer, Types::Class);

    groupControl = form.addControl(FormControlType::Group, "");
    groupControl.widthMode(1);
    groupControl.heightMode(1);
    groupControl.frameType(1);

    tabControl   = groupControl.addControl(FormControlType::Tab, "");
    tabControl.widthMode(1);
    tabControl.heightMode(1);

    while (it.more())
    {
        report = it.value();

        if (! report)
        {
            it.next();
            continue;
        }
     
        dsName = dictEnum.index2Symbol(report.reportType());

        formBuildDataSource = form.addDataSource(dsName);
        formBuildDataSource.table(tableNum(OfficialsTrans_RU));

        pageControl = tabControl.addControl(FormControlType::TabPage, "");
        pageControl.caption(report.description());
        pageControl.dataSource(dsName);
        pageControl.widthMode(1);
        pageControl.heightMode(1);
        gridControl = pageControl.addControl(FormControlType::Grid, "");
        gridControl.widthMode(1);
        gridControl.heightMode(1);
        gridControl.dataSource(dsName);

 
        realControl     = gridControl.addDataField(formBuildDataSource.id(), fieldNum(OfficialsTrans_RU, LineNum));
        realControl.name("LineNum");
 
        comboBoxControl = gridControl.addDataField(formBuildDataSource.id(), fieldNum(OfficialsTrans_RU, Position));
        comboBoxControl.name("PositionCtrl");

        control2Class.insert(comboBoxControl.id(), report);

        stringControl = gridControl.addDataField(formBuildDataSource.id(), fieldNum(OfficialsTrans_RU, Name));
        stringControl.name("NameCtrl");
        stringControl.lookupButton(2);


        control2Class.insert(stringControl.id(), report);

        comboBoxControl = gridControl.addDataField(formBuildDataSource.id(), fieldNum(OfficialsTrans_RU, Title));
        comboBoxControl.name("TitleCtrl");

        control2Class.insert(comboBoxControl.id(), report);

        it.next();
    }

    args = new Args();
    args.object(form);
    args.caller(this);

    formRun         = classFactory.formRunClass(args);
    form            = formRun.form();

    formRun.init();

    it.begin();

    while (it.more())
    {
        report = it.value();
   
        if (! report)
        {
            it.next();
            continue;
        }
   

        dsName = dictEnum.index2Symbol(report.reportType());

        formDataSource = formRun.dataSource(dsName);

        qbds = formDataSource.query().dataSourceName(dsName);
        qbds.addRange(fieldNum(OfficialsTrans_RU, OffsessionId)).value(report.getOffSessionId());
        qbds.addRange(fieldNum(OfficialsTrans_RU, reportType)).value(sysQuery::value(InventJournalReport_RU::inventJournalReportType2OffReportType(report.reportType())));
     
        qbds.addSortField(fieldNum(OfficialsTrans_RU, LineNum));

        offSessionId    = report.getOffSessionId(); 
        it.next();
    }

    formRun.run();
    formRun.wait();

}
