我一直在努力让WPF多数据触发器在基于此控件http://marcangers.com/animated-switch-togglebutton-style-in-wpf/的自定义ToggleButton上触发故事板动画。切换按钮是常规WPF ToggleButton的扩展,其自定义属性为Status,将显示为Modified或Unmodified。我的MultiDataTrigger触发了togglebutton IsChecked以及状态是修改还是未修改。问题是,故事板根本没有触发。当我在常规触发器中有故事板动画时它可以正常工作。这是自定义切换按钮。
CustomToggleButton.xaml
<ToggleButton x:Class="DPC9600CustomControlLibrary.CustomToggleButton"

<ToggleButton.Style>
<Style TargetType="{x:Type ToggleButton}" BasedOn="{StaticResource CustomToggleButton}"/>
</ToggleButton.Style>
</ToggleButton>
CustomToggleButton.xaml.cs
public partial class CustomToggleButton : ToggleButton
{
public static readonly DependencyProperty StatusProperty =
DependencyProperty.Register("Status", typeof(ConfigurationValueStatus), typeof(CustomToggleButton));
public ConfigurationValueStatus Status
{
get { return (ConfigurationValueStatus) GetValue(StatusProperty); }
set { SetValue(StatusProperty, value); }
}
public CustomToggleButton()
{
InitializeComponent();
}
}
这是我在Styles_CustomToggleButton.xaml中的多数据触发器

我不确定我做错了什么,使用常规触发器使动画工作。这是一个触发器的视图。

我无法在您的XAML中找到Myself
的定义。
如果这是Style.Triggers
(我很确定),我认为Status
的绑定应该是{Binding Status, RelativeSource={RelativeSource Self}
,就像你的IsChecked
一样} 捆绑。
如果我错了并且它在ControlTemplate.Triggers
中,我会尝试{Binding Status, RelativeSource={RelativeSource TemplatedParent}
- 同样适用于IsChecked
。

问题在于<Condition Binding="{Binding Status,ElementName=Myself}" Value="Modified"/>
所有我必须做的就是将其切换为<Condition Binding="{Binding Status, RelativeSource={RelativeSource=Self}}" Value="Modified"/>
此更改修复了样式触发器。
