将telerik控件绑定到可见性属性会引发运行时错误

Question

当我试图将可见性属性绑定到telerik控件时遇到问题。当我将同一个属性绑定到一个常规控件时，它可以正常工作。

Visibility。Collapsed和Telerik.Windows.Controls.Charting.SeriesVisibility.Collpsed我都试过了，但我仍然得到以下错误

Set属性引发了"Telerik.Windows.Controls.Charting.SeriesDefinition.Visibility"一个例外。

在Initialize（）上引发此错误；

这是我的代码

视图（代码隐藏）：

public ChartView(ViewModel viewModel)
{
    InitializeComponent();
}

ViewModel:

private Telerik.Windows.Controls.Charting.SeriesVisibility _startDateVisible;
public Telerik.Windows.Controls.Charting.SeriesVisibility StartDateVisible 
{ 
    get {return _startDateVisible;} 
    set 
    {
        _startDateVisible = value;
        OnPropertyChanged("StartDateVisible");
    }
}
public ViewModel(IEventAggregator eventAggregator)
            : base(eventAggregator)
{
     StartDateVisible = Telerik.Windows.Controls.Charting.SeriesVisibility.Collapsed;
     //StartDateVisible = Visibility.Collapsed;
}

视图（XAML）:

<telerikCharting:SeriesMapping x:Name="..." LegendLabel="..." CollectionIndex="1" ChartAreaName="...">
   <telerikCharting:SeriesMapping.SeriesDefinition>
       <telerikCharting:ScatterSeriesDefinition ShowItemLabels="True" ShowItemToolTips="True" PointShape="Circle" Visibility="{Binding StartDateVisible}"  />
       </telerikCharting:SeriesMapping.SeriesDefinition>
   <telerikCharting:SeriesMapping.ItemMappings>
   <telerikCharting:ItemMapping DataPointMember="XValue" FieldName="..."/>
   <telerikCharting:ItemMapping DataPointMember="YValue" FieldName="..."/>
</telerikCharting:SeriesMapping.ItemMappings>
</telerikCharting:SeriesMapping>

发现由于依赖性问题，这是不可能的。
