Range
in namespace DotVVM.Framework.Controls.Bootstrap4
Renders Bootstrap Range input control.
Usage & Scenarios
Renders the Bootstrap range form control.
Sample 1: Basic Range
The MinValue
and MaxValue
properties specify the boundaries for selected values.
The Step
property defines the difference between selectable values.
The SelectedValue
property contains a binding to a viewmodel property with value selected in the range control.
<bs:Range MinValue="0" MaxValue="2000" Step="10"
SelectedValue="{value: Value}" />
{{value: Value}}
public class ViewModel : DotvvmViewModelBase
{
public double Value { get; set; } = 1000;
}
Sample 2: Range Changes
The Changed
event occurs when the user changes the selected value.
The Enabled
property can be used to enable and disable the control.
<bs:Range MinValue="0" MaxValue="2000" Step="10"
SelectedValue="{value: Value}"
Changed="{command: OnValueChanged()}"
Enabled="{value: Enabled}" />
<p>Value: {{value: Value}}</p>
<p>Number of changes: {{value: ValueChanges}}</p>
<p><bs:CheckBox Text="Allow changes" Checked="{value: Enabled}" /></p>
public class ViewModel : DotvvmViewModelBase
{
public double Value { get; set; } = 1000;
public int ValueChanges { get; set; }
public bool Enabled { get; set; } = true;
public void OnValueChanged()
{
ValueChanges++;
}
}
