This section guides you through setting up and configuring a Slider in your .NET MAUI application. Follow the steps below to add a basic Slider to your project.

To quickly get started with the .NET MAUI Slider, watch this video.

Prerequisites

Before proceeding, ensure the following are in place:

1. Install .NET 7 SDK or later.
2. Set up a .NET MAUI environment with Visual Studio 2022 (v17.3 or later) or Visual Studio Code. For Visual Studio Code users, ensure that the .NET MAUI workload is installed and configured as described here.

Step 1: Create a New MAUI Project

Visual Studio

1. Go to File > New > Project and choose the .NET MAUI App template.
2. Name the project and choose a location. Then, click Next.
3. Select the .NET framework version and click Create.

Visual Studio Code

1. Open the Command Palette by pressing Ctrl+Shift+P and type .NET:New Project and press Enter.
2. Choose the .NET MAUI App template.
3. Select the project location, type the project name and press Enter.
4. Then choose Create project

Step 2: Install the Syncfusion MAUI Sliders NuGet Package

1. In Solution Explorer, right-click the project and choose Manage NuGet Packages.
2. Search for Syncfusion.Maui.Sliders and install the latest version.
3. Ensure the necessary dependencies are installed correctly, and the project is restored.

Step 3: Register the Handler

Syncfusion.Maui.Core nuget is a dependent package for all Syncfusion controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion core.

C#

using Microsoft.Maui;
using Microsoft.Maui.Hosting;
using Microsoft.Maui.Controls.Compatibility;
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Syncfusion.Maui.Core.Hosting;

namespace SliderGettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });

            return builder.Build();
        }
    }
}

Step 4: Add a Basic Slider control

Import the SfSlider namespace and initialize the slider as shown below.

XAML

<ContentPage
    . . .
    xmlns:sliders="clr-namespace:Syncfusion.Maui.Sliders;assembly=Syncfusion.Maui.Sliders">
    <Grid>
        <sliders:SfSlider />
    </Grid>
</ContentPage>

C#

using Syncfusion.Maui.Sliders;

namespace SliderGettingStarted
{
    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();
            SfSlider slider = new SfSlider();
            this.content = slider;
        }
    }
}

Enable labels

The ShowLabels property enables the labels which renders on given interval.

XAML

<sliders:SfSlider Minimum="0"
                  Maximum="10"
                  Value="5"
                  ShowLabels="True"
                  Interval="2" />

C#

SfSlider slider = new SfSlider()
{
    Minimum = 0,
    Maximum = 10,
    Value = 5,
    Interval = 2,
    ShowLabels = true,
};

Enable ticks

The ShowTicks property enables the ticks in the range selector, while the MinorTicksPerInterval property enables the minor ticks between the major ticks.

XAML

<sliders:SfSlider Minimum="0"
                  Maximum="10"
                  Value="5"
                  Interval="2"
                  ShowTicks="True"
                  ShowLabels="True"
                  MinorTicksPerInterval="1" />

C#

SfSlider slider = new SfSlider()
{
    Minimum = 0,
    Maximum = 10,
    Value = 5,
    Interval = 2,
    ShowLabels = true,
    ShowTicks = true,
    MinorTicksPerInterval = 1
};

Orientation

The Orientation property allows you to show the slider in both horizontal and vertical directions. The default value of the Orientation property is Horizontal.

XAML

<sliders:SfSlider Orientation="Vertical"
                  Minimum="0"
                  Maximum="10"
                  Value="5"
                  Interval="2"
                  ShowLabels="True"
                  ShowTicks="True"
                  MinorTicksPerInterval="1" />

C#

SfSlider slider = new SfSlider()
{
    Orientation = SliderOrientation.Vertical,
    Minimum = 0,
    Maximum = 10,
    Value = 5,
    Interval = 2,
    ShowLabels = true,
    ShowTicks = true,
    MinorTicksPerInterval = 1
};

Inverse the slider

Invert the slider using the IsInversed property. The default value of the IsInversed property is False.

XAML

<sliders:SfSlider Minimum="0"
                  Maximum="10"
                  Value="5"
                  IsInversed="True"
                  Interval="2"
                  ShowTicks="True"
                  ShowLabels="True"
                  MinorTicksPerInterval="1" />

C#

SfSlider slider = new SfSlider()
{
    Minimum = 0,
    Maximum = 10,
    Value = 5,
    IsInversed = true,
    Interval = 2,
    ShowLabels = true,
    ShowTicks = true,
    MinorTicksPerInterval = 1
};

Formatting labels

Add prefix or suffix to the labels using the NumberFormat property.

XAML

<sliders:SfSlider Minimum="20"
                  Maximum="100"
                  Value="60"
                  Interval="20"
                  NumberFormat="$##"
                  ShowLabels="True"
                  ShowTicks="True"
                  MinorTicksPerInterval="1" />

C#

SfSlider slider = new SfSlider()
{
    Minimum = 20,
    Maximum = 100,
    Value = 60,
    Interval = 20,
    NumberFormat = "$##",
    ShowLabels = true,
    ShowTicks = true,
    MinorTicksPerInterval = 1
};
