Range Slider

Range Slider

The RangeSlider component allows users to choose a range of numeric values. This demo shows how you can create and configure a RangeSlider.

Create a RangeSlider

To create a RangeSlider, declare it in markup and specify the following four properties:

  • start and end
    Specify the selected interval.

  • min and max
    Limit the range of accepted values.

You can see the resulting RangeSlider in the Default mode section of this demo.

Customize RangeSlider Appearance

The RangeSlider can display labels for the min and max values. To configure the labels, use the label object. In this object, set the visible property to true to display the labels. You can also specify the position and format properties.

The RangeSlider can also display a tooltip for slider handles. To display tooltips, you need to configure the tooltip object:

  • Set the enabled property to true to display tooltips.

  • Specify the tooltip position.

  • Specify the format property.

  • Assign 'onHover' or 'always' to the showMode property to change how the component shows tooltips.

Use the showRange property to specify if the selected range should be highlighted. You can also use the step property to specify the value change step for the RangeSlider.

If you want to disable the RangeSlider, set the disabled property to true.

Handle the Value Change Event

Specify the onValueChanged function to handle the value change. In this demo, the NumberBox components and the RangeSlider use this property to exchange values. You can use one of these components to change the range.
