  • You can use the File Upload UI Pattern to allow users upload files to the app.

    The File Upload pattern is commonly used in a form, but it can also be used as a stand-alone element.

    How to use the File Upload Pattern

    1. In Service Studio, in the Toolbox, search for File Upload.

      The File Upload 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 File Upload widget into the Main Content area of your application's screen.

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