Create lookup for simple unbound stringcontrol

The following code is intended to demonstrate how to add lookup functionality to a data-unbound StringControl.

[Control("String")]
class FormStringControl1
{
    public void lookup()
    {
        //super();
        SysTableLookup systableLookup =
            SysTableLookup::newParameters(tableNum(CustGroup), this);

        systableLookup.addLookupfield(fieldNum(CustGroup, CustGroup), true);
        systableLookup.addLookupfield(fieldNum(CustGroup, Name), false);
        systableLookup.performFormLookup();
    }
}

The next example is an extension of the above, but now a query is used to limit the values ??to be displayed.

[Control("String")]
class FormStringControl1
{
    public void lookup()
    {
        //super();
        SysTableLookup systableLookup =
            SysTableLookup::newParameters(tableNum(CustGroup), this);
        Query query;

        query = new Query();
        query.addDataSource(tableNum(CustGroup));

        query.dataSourceTable(tableNum(CustGroup)).addRange(
            fieldNum(CustGroup, CustGroup)).value("??");
        systableLookup.parmQuery(query);

        systableLookup.addLookupfield(fieldNum(CustGroup, CustGroup), true);
        systableLookup.addLookupfield(fieldNum(CustGroup, Name), false);

        systableLookup.performFormLookup();
    }
}

 

 


 
 
 

Override lookup of a field extending RecId

ScreenshotUsing the code example below, I want to show how to override the lookup method of a RecId/RefRecId field. Such a lookup is also referred to as a Referencelookup.

The example serves quite concretely to be able to select a financial dimension, but only one of the type cost center.
