When binding UI controls to Xomega data properties, Xomega Framework allows you to automatically mark required fields properties on the screen to help users visually identify them. A typical approach could be to highlight the corresponding label with a bold font. You can also set a red text color for the label for required fields, but this may be potential confused with marking invalid fields with red color.

Different UI technologies mandate different implementations of this approach. The following tutorials described the steps for each of the UI technologies.
