Adding filter on form with one and multiple range values

1.Created two tables and on e form

2. Take an EDT and give relation to PCustomerTable.CustomerId and extends to outbound control on form(openmode:edit)

3.

In clicked method
PCustomerTable_ds.filter(fieldNum(PCustomerTable,CustomerId),FilterButton.valueStr());

4.

For multiple selection:

In form methods:

public void multiLookup()

{

    Query query = new Query();

    QueryBuildDataSource qbds;

    qbds = query.addDataSource(tableNum(PCustomerTable));

    msCtrlCust = SysLookupMultiSelectCtrl::constructWithQuery(element, CustomerIDFilter, query);

}

public void init()

{

    super();

    element.multiLookup();

}

public class FormRun extends ObjectRun

{

    SysLookupMultiSelectCtrl msCtrlCust;

    container                values;

}

5. In PCustomerTable -->executequery()

public void executeQuery()

{

    PCustomerTable       ptc;

    PItemTransactions    pit;

    query                query;

    QueryBuildDataSource qbds,qbds1;

    QueryBuildRange      qbr;

    QueryRun             qr;

    int                  i;

    int64                r;

    container            c;

    ;

    query = new query();

    qbds  = query.addDataSource(tableNum(PCustomerTable));

    qbds1 = qbds.addDataSource(tableNum(PItemTransactions));

    qbds1.relations(true);

    values = msCtrlCust.get();

    for (i = 1; i <= conLen(values);i++)

    {

        r = conPeek(values,i);

        Ptc = PCustomerTable::find(r);

        c = conIns(c,i,Ptc.CustomerId);

    }

    qbds.addRange(fieldNum(PCustomerTable,CustomerId)).value(con2Str(c));

    qr = new QueryRun(query);

    while (qr.next())

    {

        ptc = qr.get(tableNum(PCustomerTable));

        PCustomerTable_ds.query(qr.query());

    }

    super();

}
