Implementation of lookup

Business Central/NAV Developers Forum

I can’t work out how the table lookup is implemented for the City field on the Customer Card Form. Neither the Lookup or LookupFormID is defined for the control, yet the lookup function is available. TIA

If a table relation is defined on a control’s source field, the system will automagically use the LookupForm for the related table (which is defined in the related table).

Thanks for that Heinz.
