I have an action based screen (no object), with a grid that the user needs to enter details into.
I need to validate that the user hasn't entered duplicate lines into the details grid.
The grid has multiple fields that make up the unique key, so I can't do an after change / control on a specific field.
I would like to validate the line after the user tabs off to the next line or clicks a button, which I can do in the NBLIG Control
action by trapping status = 75. However, setting mkstat = 2 doesn't prevent X3 from moving to the next grid line.
How can I prevent X3 moving to a new grid line if there are validation errors ?
e.g.
Subprog C_NBLIG
If (status = 75) Then
...
if (validation errors) then
mkstat = 2 # Doesn't do anything
end
endif
...
Regards,
Michael
