  • You can use the Blank State UI Pattern to inform end users, for example, to complete a task or when there is no data available for display etc.

    How to use the Blank Slate UI Pattern

    1. In Service Studio, in the Toolbox, search for Blank Slate.

      The Blank Slate widget is displayed.

      If the UI widget does not display, it may be because you used a ready-made app, which deletes unused widgets from the module. To make additional widgets available in your app:

      a. Go to Module > Manage dependencies.

      b. Search for and select the relevant Producer, for example OutSystemsUI. Ensure Show All is selected.

      c. On the Public elements for the selected Producer displayed on the right, ensure Show All is selected.

      d. Search for and select the element you want to add, and click Apply.

      e. In Service Studio, in the Toolbox, search for the widget again.

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

      By default, the Blank Slate widget contains icon, content, and action placeholders.

    3. Add your content to the placeholders.

      In this example, we change the icon to a calendar icon, enter some text in the Content placeholder, and add a button to the Actions placeholder. This button, when clicked, redirects the user to another page.

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


    Property Description
    FullHeight (Boolean): Optional Displays a larger Blank Slate, taking over full page height. If True, the Blank Slate takes over the full page height. This is the default value. If False, the Blank Slate doesn't take over the full height of the page.
    ExtendedClass (Text): Optional Adds custom style classes to the Pattern. You define your custom style classes in your application using CSS.


    • Blank - No custom styles are added (default value).
    • "myclass" - Adds the myclass style to the UI styles being applied.
    • "myclass1 myclass2" - Adds the myclass1 and myclass2 styles to the UI styles being applied.
    You can also use the classes available on the OutSystems UI. For more information, see the OutSystems UI Live Style Guide.
