For a range selection, you can use the RangeSlider control.

HTML Rendered by the Control

Sample 1: Basic Usage

The SelectedValue properties represent the value selected by the user.

The MinValue and MaxValue properties specify the start and end point of the scale.

<bp:Slider SelectedValue="{value: Value}"
           MinValue="0"
           MaxValue="100" />

<p>Selected value: {{value: Value}}</p>
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.Slider.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public int Value { get; set; } = 50;
    }
}

Sample 2: Step

The Step property defines a size of a step. The slider value is increased or decreased by this value.

<bp:Slider SelectedValue="{value: Value}"
           Step="0.1"
           MinValue="0"
           MaxValue="5" />

<p>Selected value: {{value: Value}}</p>
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.Slider.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {
        public double Value { get; set; } = 2.5;
    }
}

Sample 3: Changed Event

The Changed property specifies a command in the viewmodel that is triggered whenever the selected value change.

<bp:Slider SelectedValue="{value: Price}"
           Changed="{command: PriceChanged()}"
           MinValue="0"
           MaxValue="100" />

<p>Selected price: {{value: PriceString}}</p>
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.Slider.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {
        public int Price { get; set; } = 50;
        public string PriceString { get; set; }

        public void PriceChanged()
        {
            PriceString = $"{Price}$";
        }
    }
}
