Hi!
I am working with Paradox 10.

I have created a form where you can enter Data to a table. If the user leaves one of the fields blank, I want this field on the form to turn red.
I have tried it with this code, but it doesn't work:

method action(var eventInfo ActionEvent)
if eventInfo.id() = DataArriveRecord then
doDefault
if Seminarnummer.Value = ("blank") then
self.Color = red
else
self.Color = transparent
endif
endif
endmethod

I also tried this method, but Paradox 10 seems to not know this method:

method changeColor()
if Seminarnummer.Value = ("blank") then
self.Color = red
else
self.Color = transparent
endif
endMethod


How can I solve this Problem?

You should experiment with the two methods NewValue and ChangeValue.

Do remember that they're visible only if you've turned on the Avdanced ObjectPAL mode from paradox's options dialog box.

Bye!
