Design form controls

For each form, define the applicable controls. A control is a UI element of the form, for example, a field, a button, or a text.
For several types of form controls, you also need to define the control event procedure. A control event procedure has one or more actions that are done on a specific control event, like text changed or button clicked.
If your company uses different types of mobile devices, controls can require a different layout for each device.
