When you are building a UX component, you add controls to the UX by selecting controls from the toolbox on the left edge of the UX Builder. The Data section has an item called [More...] which allows you to select from several additional control types. These additional control types are created by Alpha Software. Now, you can create your own controls and when you click the [More...] item, your user-defined controls will be listed. The controls that you create are all based on the ViewBox control.

In this video we show how to create a Custom UX Data Control and then how to add a new control to your UX that is based on this custom control.
