在 UserControl 中找不到附加属性资源

Question

在为我的用户控件添加资源期间，出现上述错误。可能是什么问题？

<UserControl x:Class="PartitionManager.DocStorageView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        <WpfToolkit:DataGrid.Columns>
            <WpfToolkit:DataGridCheckBoxColumn
                Header="Select"
                Binding="{Binding Path=IsSelected}"/>
            <WpfToolkit:DataGridTextColumn
                Header="InterestingName" 
                Binding="{Binding Path=InterestingName}"/>
        </WpfToolkit:DataGrid.Columns>
    </WpfToolkit:DataGrid>
</UserControl>

您是否可能搞乱了代码隐藏中的继承？

您的类需要继承自 UserControl：

 public partial class DocStorageView : UserControl
 { /*...*/ }
