ItemsControl的绑定可视性

我已经使用下面的代码片段来绑定ItemsControl的可视性。ItemsControl的绑定可视性

<ItemsControl x:Name="PART_ItemsControl" 
     Margin="{Binding ExcelLikeFilterAdvVisibility, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource marginConverterForOldExcelLikeFiltering}, ConverterParameter=ItemsControl}" 
     ItemsSource="{TemplateBinding ItemsSource}" 
     Visibility="{Binding Path=Items.Count, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource itemsSourceCountConverter}}">

由于此代码片段，我在输出窗口中出现以下错误。

错误：

System.Windows.Data Error: BindingExpression path error: 'Items' property not found on 'ToolTipsDemo.StocksViewModel' 'ToolTipsDemo.StocksViewModel' (HashCode=42842654). BindingExpression: Path='Items.Count' DataItem='ToolTipsDemo.StocksViewModel' (HashCode=42842654); target element is 'System.Windows.Controls.ItemsControl' (Name='PART_ItemsControl'); target property is 'Visibility' (type 'System.Windows.Visibility')..

罗伯特你好，请立即检查。 – 2013-04-24 16:50:26

你的itemscontrol的datacontext似乎是Type StocksViewModel，并且该viewmodel没有Items属性 – 2013-04-24 16:51:55

Visibility="{Binding Path=Items.Count, 
        RelativeSource={RelativeSource Self}, 
        UpdateSourceTrigger=PropertyChanged, 
        Converter={StaticResource itemsSourceCountConverter}}">
