Slider
in namespace DotVVM.BusinessPack.Controls
Renders a Slider control that allows the user to select a single numeric value on a scale.
Usage & Scenarios
Renders a slider with a numeric scale which allows the user to select a value.
For a range selection, you can use the RangeSlider 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 = $"{Price}$";
}
}
