Using Choice Set

A choice set is a type of a Data Service field, used to store an enumerated list of selectable items.

You can use a choice set to select an expense type, a forum post category, or a certain edition of a recurring event.

You can bind choice sets to the following controls:

• Dropdown

• Multiselect dropdown

• List

• Radio Button

  note

  Binding choice sets to a list source returns the options in that choice set.

  Binding choice sets to a selected item binds the field value of that selected item.

  When bounding to a selected item, it will bind the field value to that selected item.

Before you start

Make sure:

• the entity with choice sets is imported in your app.
• you have the proper permissions from Data Service.

Procedure

This example uses an entity called Fauna that has the following fields:

• Animals - type Choice Set, multiple selection not allowed
• Continent - type Choice Set, multiple selection allowed
• Endangered - type Choice Set, multiple selection not allowed

1. In your app, add the Fauna entity. You must include at least one entity to use the GetChoiceSet() function.
2. Add a Dropdown control and configure it as follows:
   1. In the List Source field, reference the Animals choice set:

      GetChoiceSet("Animals")

   2. In the Column field, write "DisplayName". This displays the display name of the choice set as an option in your control.
3. Add a Multiselect dropdown control and configure it as follows:
   1. In the List Source field, reference the Continent choice set:

      GetChoiceSet("Continent")

   2. In the Column field, write "DisplayName". This displays the display name of the choice set as an option in your control.
4. Add a Radio Button control and configure it as follows:
   1. In the List Source field, reference the Endangered choice set:

      GetChoiceSet("Endangered")

   2. In the Column field, write "DisplayName". This displays the display name of the choice set as an option in your control.
