Introduction

Lookups are the standard way to display a list of possible selection values to the user, while editing or creating database records. Normally, standard lookups are created automatically by the system, and are based on extended data types and table setup. It is also possible to override the standard functionality by creating your own lookups from the code or using the Dynamics AX forms.

In this chapter, we will cover various lookup types, such as file selector, color picker, or tree lookup, as well as the different approaches to create them.
