Did you consider to keep a button inactive till all needed options become filled?
No, I didnt ...... I don't really understand what you mean
Do you mean that the OK button should be disabled until all fields are filled in?
Which would mean that each field would need a callback function which would check the fields - enabling the button when all are ok.
Is this your intention?
I mentioned button.enabled property set to false initially.
And yes - code should collect each mandatory field contents using, i.e. onChange event.
If "everything" is true ==> button.enabled == true;
Just in short...
It worked perfectly
Thanks for the advice!
