Custom label on SysTableLookup column

Good evening,

This shows how to put a custom label on a SysTableLookup:

public static void lookupSalesId(FormStringControl _ctrl)
{
    SysTableLookup sysTableLookup =
        SysTableLookup::newParameters(tablenum(SalesTable), _ctrl);
    Query query = new Query();
    ;

query.addDataSource(tablenum(SalesTable));

//'true' is used to specify which field we are returning from the lookup.

//By default the first field added is returned, so here 'true' is superfluous.

sysTableLookup.addLookupfield(fieldnum(SalesTable, SalesId), true);

//Use this setLabel() call right after the adding the field you need to customize
sysTableLookup.setLabel("My custom SalesId label" );

sysTableLookup.addLookupfield(fieldnum(SalesTable, SalesName));

sysTableLookup.parmQuery(query);
sysTableLookup.performFormLookup();
}

Normally, you would define this static lookupSalesId() method on the table SalesTable, since it is closely related. Then you could call this method from a form by overriding the lookup() method of a Form's Data Source field as such (logically, a field of the same type as the one you're looking up):

public void lookup(FormControl _formControl, str _filterStr)
{

;

SalesTable::lookupSalesId(formControl);
}
