  • You can use the Range Slider Interval Pattern to allow users select a single value between two range values. This pattern enables the adjustment of content by predetermined intervals and within a chosen range. Moving the slider along the track, increases or decreases the value.

    How to use the Range Slider Interval UI Pattern

    In this example, we create a Range Slider Interval that allows the user select a price range between 1-50.

    1. In Service Studio, in the Toolbox, search for Range Slider Interval.

      The Range Slider Interval 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 Range Slider Interval widget into the Main Content area of your application's screen, and on the Properties tab, enter the MinValue, MaxValue, InitialIntervalStart, and InitialIntervalEnd values. In this example, we add static values.

    3. To create an OnChange event, on the Properties tab, from the Handler drop-down, select New Screen Action.

      By default, the SelectedMinValue and SelectedMaxValue input parameter are created.

    4. To create a variable for each of the expressions, right-click your screen name, select Add Local Variable, and on the Properties tab, enter a name and data type. In this example we create the LowerPrice and HighestPrice variables with the Currency data type.

    5. So that the parameters read the range slider selections, double-click your screen action, from the Toolbox, add the Assign action to the screen action, and set the variable and value assignments for the Assign action.

    6. To display your selection, go back to your screen, and from the Toolbox, drag the Container widget into the Main Content area of your application's screen, enter a name and add your content to the Container placeholder. In this example, we enter DisplayValue for the name and add some text and an expression for each of the input parameters.

    7. Go back to the screen action, and from the Toolbox, add the Ajax Refresh action to the screen action, and in the Select Widget pop-up, navigate to and select the Container widget name (in this example, DisplayValue), and click OK.

    8. To bind the SelectedMinValue variable to the expression, double-click the expression widget, and in the Expression Value editor, select the variable you just have created, and click Done.

    9. Repeat step 8 for the SelectedMaxValue input parameter.

    10. From the Properties tab, you can change the Range Slider's look and feel by setting the (optional) properties.

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