Are using Delphi 7 development, now have a problem. So, is the main table lookup table, the table is the entity list, master-slave relationship between tables,
When changes and save from the table, the picture is empty, which means that the query and edit table is not synchronized, seek a solution

CodePudding user response:

Is directly used to control set of master-slave mode?

I write my own code principal-subordinate: from that it corresponds to the current record of the main table
