Quick Start

1. Install NuGet Package

<PackageReference Include="Syncfusion.Sliders.WinUI" Version="Latest" />

2. Add Namespace

<Page xmlns:slider="using:Syncfusion.UI.Xaml.Sliders">

3. Basic Implementation

<slider:SfRangeSlider 
    RangeStart="30"
    RangeEnd="70"
    ShowLabels="True"
    ShowTicks="True" />

4. Code-Behind

using Syncfusion.UI.Xaml.Sliders;

SfRangeSlider rangeSlider = new SfRangeSlider();
rangeSlider.Minimum = 0;
rangeSlider.Maximum = 100;
rangeSlider.RangeStart = 30;
rangeSlider.RangeEnd = 70;
rangeSlider.ShowLabels = true;
rangeSlider.ShowTicks = true;
this.Content = rangeSlider;

Common Patterns

Price Range Filter

<slider:SfRangeSlider 
    Minimum="0"
    Maximum="1000"
    Interval="100"
    RangeStart="200"
    RangeEnd="800"
    ShowLabels="True"
    ShowTicks="True"
    ShowTooltip="True" />

Custom Styled Range Slider

<slider:SfRangeSlider 
    RangeStart="25"
    RangeEnd="75"
    ShowLabels="True"
    ShowTicks="True"
    ShowDividers="True"
    ActiveTrackHeight="4"
    InactiveTrackHeight="4"
    DividerHeight="4"
    DividerWidth="4"
    ThumbHeight="20"
    ThumbWidth="20" />

Value Change Tracking

<slider:SfRangeSlider 
    x:Name="rangeSlider"
    RangeStart="30"
    RangeEnd="70"
    RangeValueChanged="OnRangeChanged" />

private void OnRangeChanged(object sender, RangeValueChangedEventArgs e)
{
    double oldStart = e.RangeStartOldValue;
    double oldEnd = e.RangeEndOldValue;
    double newStart = e.RangeStartNewValue;
    double newEnd = e.RangeEndNewValue;
    
    // Update UI or perform validation
    Debug.WriteLine($"Range: {newStart} - {newEnd}");
}

Common Use Cases

E-Commerce Price Filters

Use RangeSlider for filtering products by price range with labels and tooltips showing currency values.

Date Range Pickers

Implement month/year range selection with custom label formatting for calendar applications.

Audio/Video Timeline Selection

Create clip selection tools with precise range control and visual feedback.

Data Filtering Dashboards

Enable users to filter datasets by numeric ranges (age, quantity, ratings, etc.).

Settings and Configuration

Provide intuitive range selectors for app settings (volume range, brightness range, etc.).

Troubleshooting

Range values not updating:

• Ensure RangeStart and RangeEnd are within Minimum and Maximum
• Check if two-way data binding is configured correctly
• Verify RangeValueChanged event is wired up

Labels not showing:

• Set ShowLabels="True"
• Configure Interval property for label spacing
• Check MaximumLabelsCount if using automatic intervals

Ticks not visible:

• Set ShowTicks="True"
• Ensure Interval is defined
• Adjust TickOffset if needed

Tooltip not appearing:

• Set ShowTooltip="True"
• Check TooltipPlacement property
• Verify tooltip template is valid
