Script to make a textfield required field at run time

In a LiveCycle form a field is made required with the "mandatory" propertly. There have been many posts on this topic. Search the forms for "mandatory". You'll find plenty.

Thomp,

thanks for your guidance! I am able to do it now. But, I notice that the field that I want it to be mandatory does not have a red boder immediately. I need to click on that field, or scroll the form, after that I will see the red border.

Do I need to do have a script that refresh, or repaint for that field?

thanks,
Boon

Yes, it needs to be refreshed. But this action is not reliable. Acrobat highlights the fields when the form is submitted. Otherwise it's tricky. There is an AcroForm property for turning the required field highlighing on and off. You might try toggling this property:

app.runtimeHighlight = false;
app.runtimeHighlight = true;
