  • You can use the Icon Badge UI Pattern to display numerical information as a notification. For example, the Icon Badge UI pattern is frequently used to notify users about the number of unread emails, unopened messages, or new tasks they may have.

    How to use the Icon Badge UI Pattern

    The following example demonstrates how you can display the number of registered users on your platform.

    1. In Service Studio, in the Toolbox, search for Icon Badge.

      The Icon Badge widget is displayed.

    2. From the Toolbox, drag the Icon Badge widget into the Main Content area of your application's screen.

      By default, the Icon Badge contains an Icon placeholder with a pre existing icon.

    3. To create an aggregate (in this example to retrieve all the users on the platform), right-click the screen name and select Fetch Data from Database.

    4. To add a database entity, click the screen, and from the Select Source pop-up, select the relevant entity and click OK. In this example, we select the User entity.

      The aggregate GetUsers is created.

    5. To reopen your screen, select the Interface tab, and double-click on your screen name.

    6. Select the Icon Badge widget, and on the Properties tab, from the Number drop-down, select Expression Editor, and in the Expression Editor enter the following expression and click Done.

      GetUsers.Count

      The Number property is now set to display the Count property of the Aggregate you created earlier, which gets and displays the number of users on your platform.

    7. On the Properties tab, you can customize the Icon Badge's look and feel by setting any of the optional properties, for example, the color.

    After following these steps and publishing the module, you can test the pattern in your app.
