问题描述

我已将 Interaction.Triggers 设置为 ListBox 并在SelectionChanged"事件发生时执行相应的 TargetedTriggerAction,如下所示.

I have set Interaction.Triggers to ListBox and perform respective TargetedTriggerAction when 'SelectionChanged' event occurs, like below.

<ListBox x:Name="WorksheetListBox" ItemsSource="{Binding WorkSheetCollection}"
                             ItemTemplate="{StaticResource workSheetTemplate}">                              
  <i:Interaction.Triggers>
    <i:EventTrigger EventName="SelectionChanged">
        <action:WorksheetListBoxAction />
    </i:EventTrigger>
  </i:Interaction.Triggers>
</ListBox>

但我的要求是我需要将 Interaction.Triggers 设置为 ListBoxItem 的PreviewMouseDown"事件(注意:通过 ItemsSource 填充的 ListBox)

But my requirement is I need to set Interaction.Triggers to ListBoxItem's 'PreviewMouseDown' event(Note: ListBox populated via ItemsSource)

推荐答案

你可以试试这样的:

    <Style TargetType="{x:Type ListBoxItem}">
        <Style.Triggers>
            <EventTrigger RoutedEvent="PreviewMouseDown">
                <EventTrigger.Actions>
                    <action:WorksheetListBoxAction />
                </EventTrigger.Actions>
            </EventTrigger>
        </Style.Triggers>
    </Style>
