This section explains how to add the .NET MAUI SmartTextEditor control. It covers only the basic features needed to get started with the Syncfusion AI-Powered Text Editor. Follow the steps below to add a .NET MAUI AI-Powered Text Editor control to your project.

NOTE

The Smart Text Editor is distributed as part of the Syncfusion.Maui.SmartComponents package provides advanced AI-assisted features to enhance text editing and content management. Ensure your application has the required AI service configuration to enable these features.

Prerequisites

Before proceeding, ensure the following are set up:

  1. Install .NET SDK
  2. Set up a .NET MAUI Environment with Visual Studio. Supported Visual Studio Versions:
    • Visual Studio 2022: Version 17.13 or later (e.g., 17.14.7) for .NET 9 development.
    • Visual Studio 2026: Required for .NET 10 development.

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® .NET MAUI SmartComponents NuGet Package

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

using Syncfusion.Maui.Core.Hosting;
namespace GettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();

            builder.ConfigureSyncfusionCore();
            builder
            .UseMauiApp<App>()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });

            return builder.Build();
        }
    }
}

Step 4: Register the AI Service

To configure the AI services, you must call the ConfigureSyncfusionAIServices() method in the MauiProgram.cs file.

  • 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.SmartComponents.Hosting;

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

            string key = "<MENTION-YOUR-KEY>";
            Uri azureEndPoint = new Uri("<MENTION-YOUR-URL>");
            string deploymentName = "<MENTION-YOUR-DEPLOYMENT-NAME>";

            // Shows how to configure Azure AI service to the Smart Components.
            AzureOpenAIClient azureOpenAIClient = new AzureOpenAIClient(azureEndPoint, new AzureKeyCredential(key));
            IChatClient azureChatClient = azureOpenAIClient.GetChatClient(deploymentName).AsIChatClient();

            builder.Services.AddChatClient(azureChatClient);
            builder.ConfigureSyncfusionAIServices();

            return builder.Build();
        }
    }
}

    NOTE

    • You can refer to Configure Chat Client for services like Azure, OpenAI, and Ollama.
    • You can also refer to the Custom AI Service section to configure your own services, such as Claude, Gemini, DeepSeek, Groq, etc.
    • If you are using a custom AI service, there is no need to register ConfigureSyncfusionAIServices() in MauiProgram.

    Step 5: Add .NET MAUI Smart Text Editor control

    1. To initialize the control, import the Syncfusion.Maui.SmartComponents namespace into your code.
    2. Initialize SfSmartTextEditor.
    <ContentPage

    xmlns:smarttexteditor="clr-namespace:Syncfusion.Maui.SmartComponents;assembly=Syncfusion.Maui.SmartComponents">

    <smarttexteditor:SfSmartTextEditor />
</ContentPage>
    using Syncfusion.Maui.SmartComponents;
. . .

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        SfSmartTextEditor smarttexteditor = new SfSmartTextEditor();
        this.Content = smarttexteditor;
    }
}
