Question

私はユーザーコントロールを持っています:

            <custom:Widget.Header>
                <StackPanel Orientation="Horizontal">
                    <TextBlock Text="{Binding Source={StaticResource DataViewResources}, Path=Resource.StaticDataText}"

            </StackPanel>
        </custom:Widget>
    </dxlc:Tile>

    <dxlc:Tile Style="{StaticResource customizedTileStyle}"
               Height="{Binding Source={StaticResource subplantMainActualControl}, Path=ActualHeight, Converter={StaticResource tileSizeConverter}}"
               Name="actualDataTile"
               VerticalContentAlignment="Top">
        <custom:Widget Name="actualDataWidget"
                       DataContext="{Binding Path=ActualViewModel}"

            </StackPanel>
        </custom:Widget>
    </dxlc:Tile>
</dxlc:TileLayoutControl>

views:SubplantMainActualControl は次のとおりです。

<UserControl x:Class="UserInterface.Views.SubplantMainActualControl"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

         dx:ThemeManager.ThemeName="Seven"
         xmlns:views="clr-namespace:UserInterface.Views">

    <views:LayoutLabelValueControl Grid.Row="0"
                               ItemsSource="{Binding Path=ActualRepresentations}" />

</UserControl>
