我无法在 ViewModel 中的 RadTreeViewItem 上触发单击事件或鼠标按下事件。我应该使用什么语法?这是下面的相关 XAML:
<Toolkit:AccordionItem x:Name="Accordion1" Header="{Binding Header, Mode=TwoWay}" Width="200">
<ListBox x:Name="SitesList" Width="195" BorderThickness="0" ItemsSource="{Binding Games, Mode=OneWay}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<telerik:RadTreeView IsDragDropEnabled="True" IsSingleExpandPath="True"
telerikDragDrop:RadDragAndDropManager.AllowDrag="True" PreviewDragEnded="RadTreeView_PreviewDragEnded"
IsDragTooltipEnabled="False">
<telerik:RadTreeViewItem Header="{Binding siteName, Mode=TwoWay}" Tag="{Binding siteKey, Mode=TwoWay}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Click">
<cmd:EventToCommand Command="{Binding RadTreeItemClickCommand, Mode=TwoWay}" MustToggleIsEnabledValue="True"/>
</i:EventTrigger>
</i:Interaction.Triggers>
</telerik:RadTreeViewItem>
</telerik:RadTreeView>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Toolkit:AccordionItem>
