Question

因此，我正在尝试为我的样式设置EventTrigger，它似乎仅注册MouseOver事件，而不注册MouseDown事件。而且我不确定为什么。

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <Style TargetType="{x:Type Button}" x:Key="KiwiButton">
        <!--<Setter Property="Background" Value="#2ecc71"/>-->
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="FontFamily" Value="Fonts/#Roboto"/>


        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Border Background="{TemplateBinding Background}">
                        <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center">


                        </ContentPresenter>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>



        <Style.Triggers>
            <EventTrigger RoutedEvent="MouseEnter">
                <EventTrigger.Actions>
                    <BeginStoryboard>

您可以尝试使用PreviewMouseDown

为什么我的EventTrigger对我的左键不起作用？
