使用MVVMLight将命令绑定到TreeViewItem
我正在尝试使用MVVMLight将TreeViewItem Selected事件绑定到命令。
TreeViewItem是在HierarchicalDataTemplate中定义的，因此我无法添加Interaction.Triggers（如下所示）
<HierarchicalDataTemplate
x:Key="TreeViewItemTemplate"
ItemsSource="{Binding ChildReportViewModels}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Selected">
<MvvmLight_Command:EventToCommand Command="{Binding LoadReportCommand, Mode=OneWay}" />
</i:EventTrigger>
</i:Interaction.Triggers>
</HierarchicalDataTemplate>
没有找到相关结果

<HierarchicalDataTemplate x:Key="TreeViewItemTemplate" ItemsSource="{Binding ChildReportViewModels}" ItemContainerStyle="{StaticResource TreeViewItemContainerStyle}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Name}"> <i:Interaction.Triggers> <i:EventTrigger EventName="MouseLeftButtonUp"> <gs_cmd:EventToCommand Command="{Binding LoadPublicationCommand, Mode=OneWay}" CommandParameter="{Binding}" /> </i:EventTrigger> </i:Interaction.Triggers> </TextBlock> </StackPanel> </HierarchicalDataTemplate>屑凉赦
