Radio Buttons

Last update: Edit

1 Introduction

Radio Buttons are used to display and, optionally, allow the end-user to edit the value of an attribute of data type Boolean or Enumeration.

When the page is displayed to the end-user, all the possible values are listed, with a filled-in circle next to the selected value and an empty circle next to the unselected value(s). Only one value can be chosen – choosing another value deselects the current value. For example:

Radio buttons must be placed in a data widget and display an attribute of the object(s) retrieved by that widget. The name of the attribute to be displayed is shown inside the radio button widget, between square brackets, and colored blue.

For example, the following image contains two sets of radio buttons. The first allows the end-user to see, and set, the value of an enumeration identifying the preferred time to contact this person (PreferredContact). The second allows the end-user to see, and set, a Boolean indicating whether this is a Personal contact.

2 Properties

An example of radio button properties is represented in the image below:

Radio button properties consist of the following sections:

2.1 Common Section

For more information on properties in this section, see the Common Section section in Properties Common for Widgets.

2.2 Data Source Section

This selects which attribute will be used within the widget. You can only select attributes which have the correct data type(s).

For more information on selecting a data source, see the Data Source Section section in Properties Common for Widgets.

2.3 Design Properties Section

The Design Properties allow you to change spacing and alignment of the widget and hide it on phone, tablet, or desktop, if needed.

2.4 Editability Section

Editability determines whether an end-user can change the value in an input widget.

For more information on properties of this section, see the Editability Section section of Properties Common for Widgets.

2.5 Events Section

2.5.1 On Change

The on-change property specifies an action that will be executed when leaving the widget, either by using the Tab key or by clicking another widget, after the value has been changed.

For more information on properties of this section, see the Event Actions section of On Click Event & Events Section.

2.5.2 On Enter

The on-enter property specifies an action that will be executed when the widget is entered, either by using the Tab key or by clicking it with the mouse.

2.5.3 On Leave

The on-leave property specifies an action that will be executed when leaving the widget, either by using the Tab key or by clicking another widget.

This differs from the On change property in that the event will always be triggered, even if the value has not been changed.

2.6 General Section
