Understand What Will Be Shown at Runtime

At runtime, VB evaluates all the rules from bottom to top, starting with the Default rule, then moving through the built-in rules.

As long as a rule's conditions are met at runtime, the rule's property values are applied to the display. However, since rules are evaluated one at a time (starting at the bottom), the topmost rule effectively takes precedence, as it can override what was previously set by lower rules.

To help you evaluate what will be shown for fields and regions at runtime, the editor provides a pop-up viewer. To display the pop-up viewer, hover over the field or region until you see an info label, then click it:

The pop-up viewer shows all the active rules that modify a region's properties, or a field’s properties within the same region:

Let's take a closer look at the pop-up viewer:

1. Name of the field (Organization Name) that these rules pertain to.
2. Currently viewed rule, which is shown with a blue background. The conditions for each rule appears beneath the rule's name.
3. Another rule. If a rule name appears in blue, you can click it to see all the fields/regions modified by that rule (as opposed to just the selected field).
4. The Default rule, which specifies the out-of-the-box behavior. The Default rule is always active and cannot be modified. And since it doesn't have any conditions, it will always be considered "true".
