Creating Client side Custom Controls in an Alpha Anywhere List Component

When you define a List control in a UX component, one of the 'control types' that you can insert into the List is a 'Custom Control'.

A 'custom control' is computed with an Xbasic function. Because Xbasic is used to render the custom control, it means that the custom control is rendered server-side when the List is initially rendered. If your UX component has code that modifies data in the List, the server-side custom control is obviously not re-rendered.

Therefore, you might want to define your custom control using client-side Javascript.

This video shows an approach to creating client-side custom controls in a List component.

The Alpha platform is the only unified mobile and web app development and deployment environment with distinct “no-code” and “low-code” components. Using the Alpha TransForm no-code product, business users and developers can take full advantage of all the capabilities of the smartphone to turn any form into a mobile app in minutes, and power users can add advanced app functionality with Alpha TransForm's built-in programming language.
