Get Started

  1. Install package

    dotnet add package package Avalonia.Labs.CommandManager

  2. Add XML Namespace

    <UserControl xmlns="https://github.com/avaloniaui"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:lab="using:Avalonia.Labs.Catalog"
+             xmlns:rc="using:Avalonia.Labs.Input"
            mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
            xmlns:viewModels="using:Avalonia.Labs.Catalog.ViewModels"
            x:Class="Avalonia.Labs.Catalog.Views.RouteCommandView"
            x:DataType="viewModels:RouteCommandViewModel"
            HorizontalContentAlignment="Stretch"
            VerticalContentAlignment="Stretch"
            >
            ...
</UserControl>

  3. Define your's RouterCommands

    public static class ApplicationCommands
{
    public readonly static RoutedCommand Open = new RoutedCommand(nameof(Open));
    public readonly static RoutedCommand Save = new RoutedCommand(nameof(Save));
}

  4. Assign your RotedCommand

            <UniformGrid Columns="2"
                    Grid.Column="2">
            <Button Content="Open"
                    Command="{x:Static lab:ApplicationCommands.Open}"
                    CommandParameter="{Binding .}"/>
            <Button Content="Save"
                    Command="{x:Static lab:ApplicationCommands.Save}"
                    CommandParameter="{Binding .}"/>
        </UniformGrid>

  5. Binding RouterCommand to yours ViewModel

    <UserControl xmlns="https://github.com/avaloniaui"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:lab="using:Avalonia.Labs.Catalog"
            xmlns:rc="using:Avalonia.Labs.Input"
            mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
            xmlns:viewModels="using:Avalonia.Labs.Catalog.ViewModels"
            x:Class="Avalonia.Labs.Catalog.Views.RouteCommandView"
            x:DataType="viewModels:RouteCommandViewModel"
            HorizontalContentAlignment="Stretch"
            VerticalContentAlignment="Stretch"
            >
<rc:CommandManager.CommandBindings>
    <rc:CommandBinding Command="{x:Static lab:ApplicationCommands.Open}" ExecutingCommand="{Binding Open}" />
    <rc:CommandBinding Command="{x:Static lab:ApplicationCommands.Save}" ExecutingCommand="{Binding Save}" />
