Question

DesignData を使用して、デザインタイムに ItemsControl を作成しようとしています。

ファイル /DesignData/SampleAlerts.xaml の内容は次のとおりです。

<ext:AlertSource xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:ext="http://schemas.osterwalder.com/extensions"
             mc:Ignorable="d" d:IsDataSource="true" Guid="4D0E0886-575C-42F2-A777-2A36AB826D14" Name="Sample Alerts">
<ext:AlertSource.Alerts>
    <ext:AlertBase Cause="sdlfkhjsdlkfj" Id="0" IsActive="True" IsAutoReset="False" IsOwnerAlive="False" Message="skdjfhsdakjhf" Removal="skjfdhkjsdfhs" Severity="SystemFault" Source="{x:Null}"/>
    <ext:AlertBase Cause="sdlfkhjsdlkfj" Id="0" IsActive="True" IsAutoReset="False" IsOwnerAlive="False" Message="skdjfhsdakjhf" Removal="skjfdhkjsdfhs" Severity="EmergencyStop" Source="{x:Null}"/>
    <ext:AlertBase Cause="sdlfkhjsdlkfj" Id="0" IsActive="True" IsAutoReset="False" IsOwnerAlive="False" Message="skdjfhsdakjhf" Removal="skjfdhkjsdfhs" Severity="ImmediateStop" Source="{x:Null}"/>
    <ext:AlertBase Cause="sdlfkhjsdlkfj" Id="0" IsActive="True" IsAutoReset="False" IsOwnerAlive="False" Message="skdjfhsdakjhf" Removal="skjfdhkjsdfhs" Severity="CycleStop" Source="{x:Null}"/>
    <ext:AlertBase Cause="sdlfkhjsdlkfj" Id="0" IsActive="True" IsAutoReset="False" IsOwnerAlive="False" Message="skdjfhsdakjhf" Removal="skjfdhkjsdfhs" Severity="Warning" Source="{x:Null}"/>
</ext:AlertSource.Alerts>

また、ファイル /DesignData/SampleAlerts.xaml のビルドアクションは DesignData に設定されます。

このデザインデータを UI で使用しようとすると、次のようになります。

    <CollectionViewSource x:Key="AlertGroups" 
                          mc:Ignorable="d" d:DesignSource="{d:DesignData Source=/DesignData/SampleAlerts.xaml}">
        <CollectionViewSource.GroupDescriptions>
            <PropertyGroupDescription PropertyName="Severity"/>
        </CollectionViewSource.GroupDescriptions>
        <CollectionViewSource.SortDescriptions>
            <scm:SortDescription PropertyName="Severity" Direction="Descending"/>
        </CollectionViewSource.SortDescriptions>
    </CollectionViewSource>

VisualStudio ではすべて正常にビルドされますが、ビジュアルスタジオデザイナーで次の例外が発生します。

The resource 'file:///C:/Users/reto/Documents/Visual Studio 2010/Projects/PPS/HMI/DesignData/SampleAlerts.xaml#3' could not be found. It should be located at 'C:\Users\reto\Documents\Visual Studio 2010\Projects\PPS\HMI\DesignData\SampleAlerts.xaml#3' but the file is not present.

   at Microsoft.Expression.DesignModel.Core.ViewNodeManager.Instantiate(ViewNode viewNode)

また、Blend ではすべてが正常にビルドされますが、デザイナーには次のエラーが表示されます。 - タイプ 'AlertSource' は抽象的であり、明示的な値を含める必要があります。Ln 1 Col 0 - メンバー「Alerts」が認識されていないか、アクセスできません。Ln 7 列 4

タイプ AlertSource および AlertBase は、次のスケルトンを持つ抽象クラスです。

public abstract class AlertBase : IAlert
{
    public long Id { get { ... } }

    public abstract object Message { get; }

    public abstract object GetLocalizedMessage(CultureInfo culture);

    public abstract object Cause { get; }

    public abstract object GetLocalizedCause(CultureInfo culture);

    public abstract object Removal { get; }

    public abstract object GetLocalizedRemoval(CultureInfo culture);

    public AlertSource Source { get { ... } }
    AlertSource IAlert.Source { get { ... } }

    public bool IsOwnerAlive { get { ... } }

    public bool IsActive { get { ... } set { ... } }

    public abstract bool IsAutoReset { get; }

    public abstract AlertSeverity Severity { get; }

    public void Acknowledge() { ... }

    public AlertBase(long id, AlertSource owner) { ... }

    public event EventHandler Set;

    public event EventHandler Reset;

    public event EventHandler Acknowledged;
}

と

public abstract class AlertSource : IAlertSource
{
    public abstract Guid Guid { get; }

    public abstract string Name { get; }

    public ICollection<IAlert> Alerts { get { ... } }

    public AlertSource() { ... }

    public virtual bool Acknowledge(IAlert alert) { ... }

    public event NotifyCollectionChangedEventHandler CollectionChanged;

    public event EventHandler AlertSet;
    public event EventHandler AlertReset;
    public event EventHandler AlertAcknowledged;

    public IEnumerator<IAlert> GetEnumerator() { ... }

    IEnumerator IEnumerable.GetEnumerator() { ... }
}

誰かがこの問題を解決する方法を知っていますか?
