MAUI Community Toolkit

Community Toolkit Effects

Enhance your .NET MAUI applications with powerful and reusable effects from the Community Toolkit. These effects allow you to apply custom visual behaviors and modifications to your UI elements declaratively.

What are Effects?

Effects in the MAUI Community Toolkit provide a way to abstract platform-specific rendering logic for custom UI customizations. They allow you to define a common API and implement the platform-specific details in separate classes.

Getting Started

To use effects, you typically need to install the MAUI Community Toolkit NuGet package and register the necessary handler extensions in your application's MauiProgram.cs file.


// MauiProgram.cs
using CommunityToolkit.Maui;

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
            })
            .UseMauiCommunityToolkit(); // Register the toolkit

        return builder.Build();
    }
}

After registration, you can apply effects directly in your XAML.

Commonly Used Effects

UnderlineEffect

Adds an underline to a Label or Entry.

For custom effects, you can apply them using their attached property syntax.

BorderEffect

Applies a border to an element with customizable color, width, and radius.

Note: Frame control is a convenient way to achieve bordered content. Community Toolkit might offer more specific border effects for deeper customization.

ShadowEffect

Adds a shadow to an element.

Ensure the appropriate namespace for effects is included in your XAML.

GrayscaleEffect

Converts an image to grayscale.

This effect is particularly useful for image manipulation.

Creating Custom Effects

You can also create your own custom effects by inheriting from the appropriate base classes provided by the MAUI Community Toolkit or by implementing the necessary interfaces. This allows for maximum flexibility in tailoring your UI to your specific needs.
