Getting Started with .NET MAUI Range Selector

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

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

Prerequisites

Before proceeding, ensure the following are in place:

  1. Install .NET 8 SDK or later.
  2. Set up a .NET MAUI environment with Visual Studio 2022 (v17.8 or later).

Step 1: Create a New .NET MAUI Project

  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.

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 RangeSelector
{
    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 Range Selector

    Import the SfRangeSelector namespace and initialize the Range Selector as shown below.

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

namespace GettingStarted
{
    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();
            SfRangeSelector rangeSelector = new SfRangeSelector();
            content = rangeSelector;
        }
    }
}

    Prerequisites

    Before proceeding, ensure the following are set up:

    1. Install .NET 8 SDK or later is installed.
    2. Set up a .NET MAUI environment with Visual Studio Code.
    3. Ensure that the .NET MAUI extension is installed and configured as described here.

    Step 1: Create a New .NET MAUI Project

    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. Press Ctrl + ` (backtick) to open the integrated terminal in Visual Studio Code.
    2. Ensure you’re in the project root directory where your .csproj file is located.
    3. Run the command dotnet add package Syncfusion.Maui.Sliders to install the Syncfusion® .NET MAUI Sliders package.
    4. To ensure all dependencies are installed, run dotnet restore.

    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 RangeSelector
{
    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 Range Selector

    Import the SfRangeSelector namespace and initialize the Range Selector as shown below.

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

    using Syncfusion.Maui.Sliders;

namespace GettingStarted
{
    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();
            SfRangeSelector rangeSelector = new SfRangeSelector();
            content = rangeSelector;
        }
    }
}

    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. If not, Open the Terminal in Rider and manually run: dotnet restore

    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 RangeSelector
{
    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 Range Selector

    Import the SfRangeSelector namespace and initialize the Range Selector as shown below.

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

namespace GettingStarted

            SfRangeSelector rangeSelector = new SfRangeSelector();
            content = rangeSelector;
        }
    }
}

    Initialize RangeSelector

    Adding content to Range Selector

    The Content property will add the content to the Range Selector. Add any control within the Range Selector with this property. In most cases, the Charts will be added as a content.

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

    SfRangeSelector rangeSelector = new SfRangeSelector();
rangeSelector.Minimum = 10;
rangeSelector.Maximum = 20;
rangeSelector.RangeStart = 13;
rangeSelector.RangeEnd = 17;
SfCartesianChart chart = new SfCartesianChart();
DateTimeAxis primaryAxis = new DateTimeAxis();
chart.XAxes = primaryAxis;
NumericalAxis secondaryAxis = new NumericalAxis();
chart.YAxes = secondaryAxis;
SplineAreaSeries series = new SplineAreaSeries();
series.ItemsSource = (new ViewModel()).Source;
series.XBindingPath = "X";

rangeSelector.Content = chart;

    RangeSelector labels

    Enable labels

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

    RangeSelector labels

    Enable ticks

    The ShowTicks property enables the ticks in the Range Selector, while the MinorTicksPerInterval property enables the minor ticks between the major ticks.

    Inverse the Range Selector

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