Create Rules

Rules can do many things: You can retrieve images from a database, perform math, edit text, perform logic, create lists, create variables or implement functions. Rules implement business logic for the execution and managing of data.

You must have a valid Mobile Development Kit project with existing pages.

The following steps describe how to create a rule visually within your Mobile Development Kit application:

1. Right-click the Rules folder and select MDK: New Rule
2. Provide a rule name and select Finish to complete.
3. The Rule Editor displays.

For complex rule logic, it is recommended to write rules directly in JavaScript.

See Customizing Advanced Rules for more details.
