17 Sep 202417 minutes to read

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 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 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;
        }
    }
}

    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"
             xmlns:charts="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts"
             xmlns:local="clr-namespace:SliderTestbedSample.RangeSelector">
    
    <ContentPage.BindingContext>
        <local:ViewModel />
    </ContentPage.BindingContext>

    <sliders:SfRangeSelector Minimum="10"
                             Maximum="20"
                             RangeStart="13"
                             RangeEnd="17">
        <charts:SfCartesianChart>

            <charts:SfCartesianChart.XAxes>
                <charts:DateTimeAxis IsVisible="False"
                                    ShowMajorGridLines="False" />
            </charts:SfCartesianChart.XAxes>

            <charts:SfCartesianChart.YAxes>
                <charts:NumericalAxis IsVisible="False"
                                     ShowMajorGridLines="False" />
            </charts:SfCartesianChart.YAxes>

            <charts:SfCartesianChart.Series>
                <charts:SplineAreaSeries ItemsSource="{Binding Source}"
                                        XBindingPath="X"
                                        YBindingPath="Y">
                </charts:SplineAreaSeries>

            </charts:SfCartesianChart.Series>
        
        </charts:SfCartesianChart>
    
    </sliders:SfRangeSelector>
</ContentPage>
    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";
series.YBindingPath = "Y";
rangeSelector.Content = chart;

    RangeSelector labels

    Enable labels

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

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

    <sliders:SfRangeSelector Minimum="0" 
                             Maximum="10" 
                             RangeStart="2" 
                             RangeEnd="8"
                             Interval="2" 
                             ShowLabels="True">

        <charts:SfCartesianChart>
            ...
        </charts:SfCartesianChart>

    </sliders:SfRangeSelector>
</ContentPage>
    SfRangeSelector rangeSelector = new SfRangeSelector();
rangeSelector.Minimum = 0;
rangeSelector.Maximum = 10;
rangeSelector.RangeStart = 2;
rangeSelector.RangeEnd = 8;
rangeSelector.Interval = 2;
rangeSelector.ShowLabels = true;
SfCartesianChart chart = new SfCartesianChart();
rangeSelector.Content = chart;

    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.

    <ContentPage 
             ...
             xmlns:sliders="clr-namespace:Syncfusion.Maui.Sliders;assembly=Syncfusion.Maui.Sliders"
             xmlns:charts="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts">
    
    <sliders:SfRangeSelector Minimum="0" 
                             Maximum="10" 
                             RangeStart="2" 
                             RangeEnd="8"                       
                             Interval="2" 
                             ShowLabels="True"
                             ShowTicks="True" 
                             MinorTicksPerInterval="1">
        
        <charts:SfCartesianChart>
            ...
        </charts:SfCartesianChart>
    
    </sliders:SfRangeSelector>
</ContentPage>
    SfRangeSelector rangeSelector = new SfRangeSelector();
rangeSelector.Minimum = 0;
rangeSelector.Maximum = 10;
rangeSelector.RangeStart = 2;
rangeSelector.RangeEnd = 8;
rangeSelector.Interval = 2;
rangeSelector.ShowLabels = true;
rangeSelector.ShowTicks = true;
rangeSelector.MinorTicksPerInterval = 1;
SfCartesianChart chart = new SfCartesianChart();
rangeSelector.Content = chart;

    RangeSelector ticks

    Inverse the Range Selector

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

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

    <sliders:SfRangeSelector Minimum="0" 
                             Maximum="10" 
                             RangeStart="2" 
                             RangeEnd="8"
                             Interval="2"
                             ShowLabels="True"
                             ShowTicks="True" 
                             MinorTicksPerInterval="1" 
                             IsInversed="True">

        <charts:SfCartesianChart>
            ...
        </charts:SfCartesianChart>

    </sliders:SfRangeSelector>
</ContentPage>
    SfRangeSelector rangeSelector = new SfRangeSelector();
rangeSelector.Minimum = 0;

             xmlns:charts="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts">
    
    <sliders:SfRangeSelector Minimum="20" 
                             Maximum="100" 
                             RangeStart="40" 
                             RangeEnd="80"
                             Interval="20"
                             ShowLabels="True"
                             NumberFormat="$#" 
                             ShowTicks="True">
