Yeah... except that the button show records does not allow for a lot of liberty, you must select whether a grid or a combobox which none of them are present in form where the ADD is called from, hence my request.
Anyway, I found a way of doing it with a single line of script instead of multiple lines which is not too bad. I wish the GUI "Show Record" button had more flexibility.
The Add button must not have any action but must have an On Click event and the script is as follow:
procedure Admin_addMaint_OnClick (Sender: TObject; var Cancel: boolean);
Syntax is ShowRecord(Target form name,'Source table name',Source form and object where dbItemID is acquired from);
AND the fields where you record the data in the target table must match the name of the original FieldNames otherwise you get an error about column names!!
If someone has a better way, please share!!
