DataTrigger上枚举作为一个WPF风格的触发值 [英] DataTrigger on Enums as the trigger value on a WPF Style

问题描述

因此​​，这里就是我想要做一点简单地说，我只是要开始与code和它很可能会是有意义的。

So here's what I'm trying to do in a little nutshell, I'm just gonna start with code and it will most likely make sense.

<bl:InnerGlowBorder x:Name="glow"
                    InnerGlowColor="Teal">
  <bl:InnerGlowBorder.Style>
    <Style TargetType="bl:InnerGlowBorder">
      <Style.Triggers>
        <DataTrigger Binding="{Binding ViewUnitStatus}"
                     Value="UnitStatusModel.Pass">
          <Setter Property="InnerGlowColor"
                  Value="Green" />
        </DataTrigger>
        <DataTrigger Binding="{Binding ViewUnitStatus}"
                     Value="UnitStatusModel.Fail">
          <Setter Property="InnerGlowColor"
                  Value="Red" />
        </DataTrigger>
        <DataTrigger Binding="{Binding ViewUnitStatus}"
                     Value="UnitStatusModel.Indeterminate">
          <Setter Property="InnerGlowColor"
                  Value="Yellow" />
        </DataTrigger>
        <DataTrigger Binding="{Binding ViewUnitStatus}"
                     Value="UnitStatusModel.Warning">
          <Setter Property="InnerGlowColor"
                  Value="Orange" />
        </DataTrigger>
      </Style.Triggers>
    </Style>
  </bl:InnerGlowBorder.Style>
</bl:InnerGlowBorder>

和枚举定义：

namespace SEL.MfgTestDev.ESS.ViewModel
{
    public enum UnitStatusModel
    {
        Indeterminate,
        Pass,
        Fail,
        Warning,
    }
}

我缺少了一块，使这项工作？我发现在依赖对象的数据源枚举一些WPF的文章，我真的不喜欢这种解决方案，是不是有更多的东西简单，我可以在这里做什么？

Am I missing a piece to make this work? I've found some WPF articles on enums that rely on object data sources and I don't really like that solution, isn't there something more simple I can do here?

推荐答案

我已经找到了解决办法，这是很愚蠢的。

I have found the solution and it was quite silly.

样式设计作为一种可视化模板控制的，但它们被设计为视觉实施的基础，而不是作为一个BE-全/最终所有的可视化模型。

Styles are designed as a sort of visual template for a control, but they are designed as a base for visual implementation, not as a be-all/end-all visual model.

这样一来，我有一种情况，就是我的模板决定什么InnerGlowColor应该的。然而，通过应用属性InnerGlowColor =蒂尔的元素，我创建了有效的覆盖，无视我的视觉风格。解决的办法是简单地删除元素声明扶养属性。

As a result, I had a situation in which my template dictated what the InnerGlowColor should be. However, by applying the attribute InnerGlowColor="Teal" to the element, I've created an override in effect, ignoring my visual style. The solution was to simply remove the dependancy property in the element declaration.
