Question

我想制作我的按钮（我为ControlTemplate定义Button）以在鼠标按下时触发我的动画（单击按钮并按住鼠标按钮）。这是因为Button在点击时没有VisualState MouseUp而只有Pressed。

我希望在没有按住按钮的情况下执行动画，我只想点击并释放。

这是我的代码（你可以看到我放了但是它没有产生任何影响：

<Window.Resources>
    <Style x:Key="ButtonStyle1" TargetType="Button">
        <Setter Property="HorizontalAlignment" Value="Stretch" />
        <Setter Property="VerticalAlignment" Value="Stretch" />
        <Setter Property="HorizontalContentAlignment" Value="Center" />
        <Setter Property="VerticalContentAlignment" Value="Center" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border x:Name="BorderOfTemplate" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" RenderTransformOrigin=".5,.5">

根据this article，Silverlight的普通EventTrigger仅支持Loaded事件。

但是，使用EventTrigger中的System.Windows.Interactivity，您似乎可以使用其他活动，例如点击或 MouseLeftButtonUp 。请参阅此文章以获取示例：codeproject.com
