Wpf 刷新在样式中使用值转换器的绑定

我在项目中使用Telerik RadTimeline控件，我有一个TimelineItemTemplate模板：

<telerik:RadTimeline x:Name="myTimeline" 
                             PeriodStart="{Binding PeriodStart}"
                             PeriodEnd="{Binding PeriodEnd}"
                             VisiblePeriodStart="{Binding VisiblePeriodStart, Mode=TwoWay}"
                             VisiblePeriodEnd="{Binding VisiblePeriodEnd, Mode=TwoWay}"
                             StartPath="StartDate"
                             DurationPath="Duration"        
                             GroupPath="Title"
                             GroupExpandMode="Multiple"
                             ItemsSource="{Binding myData}"
                             TimelineItemTemplate="{StaticResource myTemplate}"
                             ScrollMode="ScrollOnly" 
                             IsSelectionEnabled="True" SelectionMode="Extended"
                             DataContext="{Binding ElementName=vm}">
</telerik:RadTimeline>

opdSettings是ObjectDataProvider：

<ObjectDataProvider x:Key="odpSettings" ObjectType="{x:Type src:AppSettings}"/>

加载应用程序时，控件会正确显示，但当应用程序运行时，我需要更改odpSettings的一些属性，这些属性会影响时间线布局，但不会显示新值

是否有方法刷新转换器绑定，以便控件显示更改？我尝试使用UpdateSourceTrigger=PropertyChanged，但没有成功

还是有其他方法可以实现我的目标

提前谢谢

我认为这是因为您在绑定中使用了Source=StaticResource，所以WPF假定该值是静态的，并且永远不会更改。您可以改为将其更改为DynamicSource，并确保它实现INotifyPropertyChanged吗？我已经在使用INotifyPropertyChanged，我尝试更改为DynamicSource，但出现了下一个错误：无法在类型绑定的源属性上设置DynamicResourceExtension。只能对DependencyObject的DependencyProperty设置DynamicResourceExtension。

<Style x:Key="myStyle" TargetType="controls:CustomTimelineControl">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="controls:CustomTimelineControl">
            <Border Height="{Binding Source={StaticResource odpSettings}, UpdateSourceTrigger=, Converter={StaticResource visibleToHeightConverter3}, ConverterParameter=Largos}" Margin="{Binding Source={StaticResource odpSettings},Path=ItemBorderMargin,Mode=OneWay}">
