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

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

Prerequisites

Before proceeding, ensure the following are set up:

  1. Install .NET 8 SDK or a later version.
  2. Set up a .NET MAUI environment with Visual Studio 2022 (v17.3 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 Core NuGet package

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

Step 3: Register the handler

The 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.Extensions.Logging;
using Syncfusion.Maui.Core.Hosting;

namespace BadgeViewGettingStarted
{
  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 Badge View

    1. To initialize the control, import the Core namespace into your code.
    2. Initialize SfBadgeView.
    <ContentPage
    . . .    
    xmlns:badgeView="clr-namespace:Syncfusion.Maui.Core;assembly=Syncfusion.Maui.Core">
    <Grid>
        <badgeView:SfBadgeView />
    </Grid>
</ContentPage>
    using Syncfusion.Maui.Core;
    namespace BadgeViewGettingStarted
    {
        public partial class MainPage : ContentPage
        {
            public MainPage()
            {
                InitializeComponent();           
                SfBadgeView badgeView = new SfBadgeView();
            }
        }   
    }

    Prerequisites

    Before proceeding, ensure the following are set up:

    1. Install the .NET 8 SDK or a later version.
    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, 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 Core 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.Core to install the Syncfusion® .NET MAUI Core package.
    4. To ensure all dependencies are installed, run dotnet restore.

    Step 3: Register the handler

    The 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.Extensions.Logging;
using Syncfusion.Maui.Core.Hosting;

namespace BadgeViewGettingStarted
{
  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 Badge View

    1. To initialize the control, import the Core namespace into your code.
    2. Initialize SfBadgeView.
    <ContentPage
    . . .    
    xmlns:badgeView="clr-namespace:Syncfusion.Maui.Core;assembly=Syncfusion.Maui.Core">
    <Grid>
        <badgeView:SfBadgeView />
    </Grid>
</ContentPage>
    using Syncfusion.Maui.Core;
    namespace BadgeViewGettingStarted
    {
        public partial class MainPage : ContentPage
        {
            public MainPage()
            {
                InitializeComponent();           
                SfBadgeView badgeView = new SfBadgeView();
            }
        }   
    }

    Prerequisites

    Before proceeding, ensure the following are set up:

    1. Ensure you have the latest version of JetBrains Rider.
    2. Install the .NET 8 SDK or a later version.
    3. Make sure the MAUI workloads are installed and configured as described here.

    Step 1: Create a new .NET MAUI project

    1. Go to File > New Solution, select .NET (C#), and choose the .NET MAUI App template.
    2. Enter the Project Name, Solution Name, and Location.
    3. Select the .NET framework version and click Create.

    Step 2: Install the Syncfusion® MAUI Core NuGet package

    1. In Solution Explorer, right-click the project and choose Manage NuGet Packages.
    2. Search for Syncfusion.Maui.Core 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

    The 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.Extensions.Logging;
using Syncfusion.Maui.Core.Hosting;

namespace BadgeViewGettingStarted
{
  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 Badge View

    1. To initialize the control, import the Core namespace into your code.
    2. Initialize SfBadgeView.
    <ContentPage
    . . .    
    xmlns:badgeView="clr-namespace:Syncfusion.Maui.Core;assembly=Syncfusion.Maui.Core">
    <Grid>
        <badgeView:SfBadgeView />
    </Grid>
</ContentPage>
    using Syncfusion.Maui.Core;
    namespace BadgeViewGettingStarted
    {
        public partial class MainPage : ContentPage
        {
            public MainPage()
            {
                InitializeComponent();           
                SfBadgeView badgeView = new SfBadgeView();
            }
        }   
    }

    Adding a badge notification text

    Add text to Badge View using the BadgeText property.

    <badgeView:SfBadgeView>        
    <badgeView:SfBadgeView BadgeText="20" />          
</badgeView:SfBadgeView>
    SfBadgeView badgeView = new SfBadgeView();

//Adding text to the badge view.

badgeView.BadgeText = "20";

this.Content = badgeView;

    Adding a content

    An image, button, label or any view can be added to the Badge View using the Content property. If you need to display a custom icon or image in the badge, ensure the image is included correctly in your project resources.

    <badgeView:SfBadgeView HorizontalOptions="Center" VerticalOptions="Center" >
        <badgeView:SfBadgeView.Content>
            <Button Text="Primary" WidthRequest="120"  HeightRequest="60"/>
        </badgeView:SfBadgeView.Content>
</badgeView:SfBadgeView>
    SfBadgeView badgeView = new SfBadgeView();
badgeView.HorizontalOptions = LayoutOptions.Center;
badgeView.VerticalOptions = LayoutOptions.Center;
//Adding image to the content of the badge view.
Button button = new Button();
button.Text = "Primary";
button.WidthRequest = 120;
button.HeightRequest = 60;
badgeView.Content = button;
Content = badgeView;

    The following code sample gives you the complete code for Badge View with badge notification types and text.

    <badgeView:SfBadgeView HorizontalOptions="Center" VerticalOptions="Center" BadgeText="20">
        <badgeView:SfBadgeView.Content>
            <Button Text="Primary" WidthRequest="120"  HeightRequest="60"/>
        </badgeView:SfBadgeView.Content>
</badgeView:SfBadgeView>
    public MainPage()
{
    InitializeComponent();
    SfBadgeView badgeView = new SfBadgeView();
    badgeView.HorizontalOptions = LayoutOptions.Center;
    badgeView.VerticalOptions = LayoutOptions.Center;
    badgeView.BadgeText = "20";

    //Adding image to the content of the badge view.
    Button button = new Button();
    button.Text = "Primary";
    button.WidthRequest = 120;
    button.HeightRequest = 60;
    badgeView.Content = button;
    Content = badgeView;
}

    The following screenshot illustrates the result of the above code.
