User Control

A minimal control customization starter without the capability to be restyled.

Minimal example

<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"
             mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
             x:Class="AvaloniaApplication1.MyUserControl">
    Welcome to Avalonia!
</UserControl>

As a templated control

As we mentioned earlier, a UserControl is a TemplatedControl with a default template. So we can set styles to make it a template.

<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:control="using:AvaloniaApplication"
             mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
             x:Class="AvaloniaApplication.MyUserControl">
    <UserControl.Styles>
        <Style Selector="control|MyUserControl">
            <Setter Property="Template">
                <ControlTemplate>
                    <TextBlock Text="Hello from template" TextAlignment="Center"  Width="200" Height="20" Background="Gray"/>
                </ControlTemplate>
            </Setter>
        </Style>
    </UserControl.Styles>
</UserControl>
