Change Field Style Trigger
The Change Field Style action enables you to change the style of the selected data entry (edit), check box, radio button, and note fields. Depending on the field type, you can apply the Normal, Read-Only, Required, or Required Read style. You can select one or multiple fields at a time using a single trigger.
For example, you can set up triggers to change the field style to Read-Only for all fields containing lab results after these fields are populated.
