Delete Button Processing

When the user selects a grid row and clicks the Delete button, the system does not update the database immediately. The engine first fires the Button Clicked event for the Delete button. At this point, the runtime structures have these values:

BC = Values from the database (from the last record read).
FC = Values from the database (if the field is a database field).
GC = Values from the database (from the selected row).
FI = Values passed from a calling form (if any).
PO = Values passed from POs.

This diagram illustrates the information in the runtime structures just before the system fires Button Clicked for the Delete button:
