🔎 Demonstration Application

The demonstration application, Atc.Wpf.Sample, functions as a control explorer. It provides quick visualization of a given control, along with options for copying and pasting the XAML markup and/or the C# code for how to use it.

🎈 Playground and Viewer for a Given Control or Functionality

The following example is taken from the ReplayCommandAsync which illustrates its usage:

• The Sample tab shows how to use the control or feature.
• The XAML tab displays the corresponding XAML markup.
• The CodeBehind tab reveals the underlying code-behind.
• The ViewModel tab displays the associated ViewModel, if used.
• The Readme tab displays the associated [control]_Readme.md, if exist.

🚀 Quick Start Guide

Installation

Add the NuGet packages to your .csproj file:

<ItemGroup>
  <!-- Core packages -->
  <PackageReference Include="Atc.Wpf" Version="4.*" />
  <PackageReference Include="Atc.Wpf.Theming" Version="4.*" />

  <!-- For form controls (LabelTextBox, LabelComboBox, etc.) -->
  <PackageReference Include="Atc.Wpf.Forms" Version="4.*" />

  <!-- For composite components (dialogs, viewers) -->
  <PackageReference Include="Atc.Wpf.Components" Version="4.*" />

  <!-- Optional: Font icons -->
  <PackageReference Include="Atc.Wpf.FontIcons" Version="4.*" />
</ItemGroup>

Configuration

1. Update App.xaml

Add the required resource dictionaries to enable theming and control styles:

<Application
    x:Class="YourApp.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:atc="https://github.com/atc-net/atc-wpf/tree/main/schemas">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <!-- Base theming styles for Light/Dark mode -->
                <ResourceDictionary Source="pack://application:,,,/Atc.Wpf.Theming;component/Styles/Default.xaml" />

                <!-- Control library styles -->
                <ResourceDictionary Source="pack://application:,,,/Atc.Wpf.Controls;component/Styles/Controls.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

2. Use Controls in XAML

Now you can use all controls with full theming support:

<Window
    xmlns:atc="https://github.com/atc-net/atc-wpf/tree/main/schemas"
    ...>

    <!-- Labeled controls with validation -->
    <atc:LabelTextBox
        LabelText="User Name"
        Text="{Binding UserName}"
        IsMandatory="True" />

    <!-- Network endpoint input -->
    <atc:LabelEndpointBox
        LabelText="API Endpoint"
        NetworkProtocol="Https"
        Value="{Binding EndpointUri}" />

    <!-- Standard WPF controls automatically themed -->
    <Button Content="Save" Command="{Binding SaveCommand}" />
    <TextBox Text="{Binding Notes}" />
</Window>

All standard WPF controls (Button, TextBox, ComboBox, etc.) are automatically styled with Light/Dark theme support.

🎯 Four-Tier Architecture

Understanding the package hierarchy and when to use each:

Tier	Package	Purpose	Example Controls
1. Base	Atc.Wpf	MVVM, layouts, converters - no UI controls	ViewModelBase, GridEx, FlexPanel
2. Controls	Atc.Wpf.Controls	Atomic/primitive controls	IntegerBox, ToggleSwitch, Flyout, Carousel
3. Forms	Atc.Wpf.Forms	Labeled form fields with validation	LabelTextBox, LabelComboBox, LabelDatePicker
4. Components	Atc.Wpf.Components	Composite high-level components	InfoDialogBox, JsonViewer, ToastNotification

Quick Guidelines:

• Use Form Controls (Atc.Wpf.Forms) for standard forms - they include labels, validation, and mandatory indicators
• Use Base Controls (Atc.Wpf.Controls) when you need custom layouts or are building composite controls
• Use Components (Atc.Wpf.Components) for dialogs, viewers, and settings panels

📋 Control Catalog at a Glance

💝 MVVM Made Easy

For MVVM infrastructure, add the Atc.XamlToolkit package to your project. This provides powerful source generators and base classes for clean MVVM architecture.

Note: As of version 4.x, Atc.Wpf no longer directly depends on Atc.XamlToolkit to optimize build performance. Add Atc.XamlToolkit directly to your project to use source generators and MVVM base classes.

Key MVVM Features (from Atc.XamlToolkit)

• Observable Properties - Automatic INotifyPropertyChanged implementation via [ObservableProperty] attribute
• Relay Commands - Simple command implementation with CanExecute support via [RelayCommand] attribute
• Async Commands - Built-in support for async/await patterns
• Source Generators - Automatic code generation for ViewModels, DependencyProperties, and AttachedProperties

MVVM Components

Component	Source	Description
ViewModelBase	Atc.XamlToolkit.Mvvm	Base class for ViewModels
ObservableObject	Atc.XamlToolkit.Mvvm	Base class implementing INotifyPropertyChanged
RelayCommand<T>	Atc.XamlToolkit.Command	Command with CanExecute support
RelayCommandAsync<T>	Atc.XamlToolkit.Command	Async command with CanExecute support
[ObservableProperty]	Atc.XamlToolkit	Source generator for properties
[RelayCommand]	Atc.XamlToolkit	Source generator for commands
[DependencyProperty]	Atc.XamlToolkit.Wpf	Source generator for WPF dependency properties
[AttachedProperty]	Atc.XamlToolkit.Wpf	Source generator for WPF attached properties

Quick MVVM Example

public partial class MainViewModel : ViewModelBase
{
    [ObservableProperty]
    private string userName = string.Empty;

    [ObservableProperty]
    private bool isEnabled = true;

    [RelayCommand(CanExecute = nameof(CanSave))]
    private async Task SaveAsync()
    {
        await SaveUserDataAsync(UserName);
    }

    private bool CanSave() => !string.IsNullOrEmpty(UserName);
}
