When you configure conditional formatting on a control based on the state of a control property such as Read-Only or Enabled, and you use the Set a control’s properties rule action to change the state of the property, the conditional formatting does not apply.
In this example we use the Read-Only property of the Comments control. The conditional format applies when the Read-Only property changes to false. The Set a control’s properties rule action changes the Read-Only property to false when a button is clicked.
Transfer the new value of the Read-Only property to a Data Label control after the Set a control’s properties rule, and then use the value of the Data Label control in the conditional format.
Follow the steps below for an example of this configuration:
