【问题描述】：

我在尝试将可见性属性绑定到 Telerik 控件时遇到问题。当我将相同的属性绑定到常规控件时，它可以正常工作。

Visibility.Collapsed 和 Telerik.Windows.Controls.Charting.SeriesVisibility.Collapsed 我都试过了，但我仍然收到以下错误

设置属性 'Telerik.Windows.Controls.Charting.SeriesDefinition.Visibility' 抛出一个例外。

Initialize() 会抛出此错误；

这是我的代码

查看（后面的代码）：

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

视图模型：

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;
}

查看 (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>
