互动，触发了内部数据模板工作不与XamlReader

我试图与分析 XamlReader.Load() 一个 DataTemplate (WPF数据表格)创造的动态背后的代码:

DataTemplate dataTemplate;

StringReader template = new StringReader($@"
<DataTemplate
    xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation""
    xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml""
    xmlns:local=""clr-namespace:MyApp;assembly=MyApp"">
<DataTemplate.Resources>
    <local:ArrayMultiValueConverter x:Key=""arrayMultiValueConverter""/>
</DataTemplate.Resources>
    <StackPanel Orientation=""Vertical"">
        <Expander VerticalAlignment=""Center"" xmlns:i=""http://schemas.microsoft.com/xaml/behaviors"">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName=""IsExpanded"">
                <i:InvokeCommandAction Command=""{{Binding DataContext.TextFilterColumn}}""/>
            </i:EventTrigger>
        </i:Interaction.Triggers>
            <Expander.Header>
                <TextBlock x:Name=""{dtColumnName}"" VerticalAlignment=""Center"" Text=""{{TemplateBinding Content}}"" Margin=""5,5,5,0"" FontWeight=""SemiBold""/>
            </Expander.Header>
            <StackPanel Orientation=""Horizontal"">
                <TextBox x:Name=""{"TbxFilter" + dtColumnName}"" Width=""100"" Margin=""5""/>
                <TextBlock Margin=""0,0,5,0"" VerticalAlignment=""Center"" FontFamily=""Segoe MDL2 Assets"">
                    <Hyperlink TextDecorations=""{{x:Null}}"" Command=""{{Binding DataContext.FilterColumnName, RelativeSource={{RelativeSource FindAncestor, AncestorType={{x:Type Window}}}}}}"">
                        <Hyperlink.CommandParameter>
                            <MultiBinding Converter=""{{StaticResource arrayMultiValueConverter}}"">
                                <Binding Path=""Text"" ElementName=""{dtColumnName}"" />
                                <Binding Path=""Text"" ElementName=""{"TbxFilter" + dtColumnName}"" />
                            </MultiBinding>
                        </Hyperlink.CommandParameter>   
                        &#xE721;
                    </Hyperlink>
                </TextBlock>
                <TextBlock Margin=""0,0,5,0"" VerticalAlignment=""Center"" FontFamily=""Segoe MDL2 Assets"">
                    <Hyperlink TextDecorations=""{{x:Null}}"" Command=""{{Binding DataContext.FilterColumnName, RelativeSource={{RelativeSource FindAncestor, AncestorType={{x:Type Window}}}}}}"">
                        <Hyperlink.CommandParameter>
                            <MultiBinding Converter=""{{StaticResource arrayMultiValueConverter}}"">
                                <Binding Path=""Text"" ElementName=""{dtColumnName}""/>
                                <Binding Path=""Text"" RelativeSource=""{{RelativeSource FindAncestor, AncestorType={{x:Type TextBlock}}}}""/>
                            </MultiBinding>
                        </Hyperlink.CommandParameter>
                        &#xe75c;
                    </Hyperlink>
                </TextBlock>
            </StackPanel>
        </Expander>
    </StackPanel>
</DataTemplate>
");

XmlReader xmlReader = XmlReader.Create(template);
dataTemplate = XamlReader.Load(xmlReader) as DataTemplate;

textColumn.HeaderTemplate = dataTemplate;

所有的是工作时，我去掉的这一部分代码:

<i:Interaction.Triggers>
    <i:EventTrigger EventName=""IsExpanded"">
        <i:InvokeCommandAction Command=""{{Binding DataContext.TextFilterColumn}}""/>
    </i:EventTrigger>
</i:Interaction.Triggers>

但是，当我将它添加，还有一个 Exception Thrown :

系统。窗户。标记。XamlParseException："无法设置未知的成员 '{http://schemas.microsoft.com/xaml/behaviors}相互作用。触发'.' 线路数量'11'和线位置'10'.'

我使用"XAML行为，"以下这一条(但同样的事情发生 Interactivity):

https://devblogs.microsoft.com/dotnet/open-sourcing-xaml-behaviors-for-wpf/

这似乎是一个问题 XamlReader.Load(xmlReader).

如果有人知道的一个解决方法，我将表示感谢。

配置：

• 框架4.8(试图与4.7.2)
• Microsoft。停靠。行为。Wpf 1.1.39

谢谢。
