CommonHelpers.Maui

This is a library containing some commonly needed helpers for .NET MAUI C#/XAML projects. The goal is to build on top of the more popular CommonHelpers package, but with .NET MAUI-specialized functionality.

Package NuGet.org Features & Docs
CommonHelpers.Maui # README

Features

Behaviors

A BehaviorBase<T> class that lets you create your own, or use the out-of-the-box EventToCommandBehavior implementation. To get started, Add the XML namespace to the view:

xmlns:behaviors="clr-namespace:CommonHelpers.Maui.Behaviors;assembly=CommonHelpers.Maui"

<SomeControl x:Name="MyControl">
    <SomeControl.Behaviors>
        <behaviors:EventToCommandBehavior EventName="Clicked" Command="{Binding MyCommand}">
    </SomeControl.Behaviors>
</SomeControl>

Converters

The library has some commonly needed value converters. To get started, Add the XML namespace to the view:

xmlns:converters="clr-namespace:CommonHelpers.Maui.Converters;assembly=CommonHelpers.Maui"

Now you can use any of these IValueConverter implementations:

  • IntToDoubleConverter
  • InvertBoolConverter
  • NullToBoolConverter
  • StringToUriConverter

As well as some boutique ones:

  • ConfigurableBoolConverter
<Grid>
    <Grid.Resources>
        <converters:ConfigurableBoolConverter x:Key="InvertBoolConv"
                                              x:TypeArguments="x:Boolean"
                                              TrueResult="False"
                                              FalseResult="True" />
    </Grid.Resources>

    <Label IsVisible="{Binding HasItems, Converter={StaticResource InvertBoolConv}}"
           Text="No Items!" />
<Grid>
  • NameToInitialsConverter
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:converters="clr-namespace:CommonHelpers.Maui.Converters;assembly=CommonHelpers.Maui"
             x:Class="YourApp.MainPage">
    <Grid>
        <ContentPage.Resources>
            <converters:NameToInitialsConverter x:Key="NameToInitialsConv">
        </ContentPage.Resources>

        <Label Text="{Binding FullName, Converter={StaticResource NameToInitialsConv}}"/>
    </Grid>
</ContentPage>

MauiApp Extensions

Extensions for platform-specific code that can be used in MauiProgram.cs.

  • For WinUI
    • window.TryMicaOrAcrylic();
  • For MacCatalyst
    • windowScene.RestrictWindowMinimumSize(new CGSize(600, 400))
    • windowScene.RestrictWindowMaximumSize(new CGSize(1920, 1080))
    • windowScene.RestrictWindowSize(new CGSize(600, 400), new CGSize(1920, 1080))
#if WINDOWS10_0_17763_0_OR_GREATER
using CommonHelpers.Maui.Platforms.Windows;

#elif MACCATALYST
using CommonHelpers.Maui.Platforms.MacCatalyst;
using UIKit;
using CoreGraphics;

#endif

public static MauiApp CreateMauiApp()
{
    // ... your other boiler plate startup code here

    builder.ConfigureLifecycleEvents(events =>
    {
    
#if WINDOWS10_0_17763_0_OR_GREATER
        events.AddWindows(wndLifeCycleBuilder =>
        {
            wndLifeCycleBuilder.OnWindowCreated(window =>
            {
                // For automatic Mica or Acrylic support
                window.TryMicaOrAcrylic();
            });
        });
    });
    
#elif MACCATALYST
    events.AddiOS(wndLifeCycleBuilder =>
    {
        wndLifeCycleBuilder.SceneWillConnect((scene, session, options) =>
        {
            if (scene is UIWindowScene windowScene)
            {
                // Can be used for restricting the MacOS window's min, max (or both) size.
                windowScene.RestrictWindowMinimumSize(new CGSize(600, 400));
            }
        });
    });
#endif
    return builder.Build();
}

More to come

This is only the beginning, I plan to build this out as an indispensable companion to the already fantastic CommonHelpers library.
