Question

Using the Windows 8 developer preview I’m trying to use a simple User Control I have created using the built in Windows Metro style template.
As yet I have not been able to get my application to resolve the reference to the control even though it is in the same project and namespace as the page referencing it. I just get “The type was not found”
I’ve looked through the “Build” samples and could not find an sample C# project that uses a user control.
Does anyone know where I could find one?

Check http://asyncui.codeplex.com/SourceControl/changeset/view/7969#139603

You can create a UserControl by right clicking your project and selecting Add/New Item (Ctrl+Shift+A) and selecting “User Control” from the list of item templates. You then name it and end up with the XAML that you can modify to add more UI like here:

<UserControl
    x:Class="Xyzzer.AsyncUI.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    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:DesignHeight="768"
    d:DesignWidth="1366">

    <Grid
        x:Name="LayoutRoot"
        Background="#FF0C0C0C">
        <Grid
            VerticalAlignment="Top"
            Height="140">
            <Grid.ColumnDefinitions>
                <ColumnDefinition
                    Width="120" />
                <ColumnDefinition
                    Width="*" />
            </Grid.ColumnDefinitions>
            <Button
                x:Name="BackButton"
                IsEnabled="False" />
            <TextBlock
                x:Name="PageTitle"
                Text="Some Page!"
                Grid.Column="1" />
        </Grid>
    </Grid>
</UserControl>

and code behind like this:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Windows.Foundation;
using Windows.UI.Popups;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Data;

namespace Xyzzer.AsyncUI
{
    partial class MainPage
    {
        public MainPage()
        {
            InitializeComponent();
        }
    }
}

You can then use that control elsewhere in XAML like this:

<xa:MainPage
    xmlns:xa="using:Xyzzer.AsyncUI" />
