Description

I want to hide the InputAccessoryView buttons that appear on the keyboard toolbar when using the Telerik UI for .NET MAUI RichTextEditor control on iOS. This is required because the RichTextEditor internally uses the MAUI WebView, and the toolbar buttons are part of the WebView's native configuration.

This knowledge base article also answers the following questions:

Solution

To hide the InputAccessoryView buttons on iOS, add custom logic for the WebView inside the MauiProgram.cs file. Follow these steps:

1. Open the MauiProgram.cs file in your project.
2. Add the following code snippet to customize the WebViewHandler:

csharp

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .UseTelerik()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
            });
#if IOS
        Microsoft.Maui.Handlers.WebViewHandler.Mapper.AppendToMapping("MyCustomization", (handler, view) => 
        {
            var myView = handler.PlatformView;
            var item = myView.InputAssistantItem;
            if (item != null)
            {
                item.LeadingBarButtonGroups = System.Array.Empty<UIKit.UIBarButtonItemGroup>();
                item.TrailingBarButtonGroups = System.Array.Empty<UIKit.UIBarButtonItemGroup>();
            }
        });
#endif
        return builder.Build();
    }
}
