创建仅适用于设计时的属性 [英] Create properties that only apply on design time

问题描述

我正在使用 Visual Studio 深色主题.因此，在设计我的视图时，如果它是黑色的，我就看不到字体.解决方法是将视图的背景设置为白色.但是我们的应用程序具有不同的主题，因此我无法对其进行硬编码.

I am using visual studio dark theme. As a result when designing my views I cannot see the font if its black. A fix will be to set the background of the view to white. But our application has different themes so I cannot hard code that.

我在创建用户控件时使用了很多很棒的属性:

There are to great properties that I use when creating an usercontrol:

d:DesignWidth="1110" d:DesignHeight="400"

这些属性只在设计时影响视图.如果我可以创建一个属性 d:DesignBackground 就太好了，这样我就不必在每次运行应用程序时添加和删除背景属性.

those properties are only affecting the view at design time. It will be great if I can create a property d:DesignBackground just so that I do not have to be adding and removing the background property every time I run the application.

推荐答案

不确定这是否正是您要查找的内容，但我所做的只是在 app.xaml 中插入一个触发器以使用 进行调用IsInDesignMode 属性如;

Not sure if it's exactly what you're looking for, but what I do is just plop a trigger in the app.xaml to invoke using the IsInDesignMode property like;

命名空间(感谢 Tono Nam)；

Namespace (Thanks Tono Nam);

xmlns:componentModel="clr-namespace:System.ComponentModel;assembly=PresentationFramework"

XAML;

<Style TargetType="{x:Type UserControl}">
    <Style.Triggers>
        <Trigger Property="ComponentModel:DesignerProperties.IsInDesignMode"
                 Value="True">
            <Setter Property="Background"
                    Value="#FFFFFF" />
        </Trigger>
    </Style.Triggers>
</Style>

简单，但有效，有时我也根据需要定位其他依赖属性，如字体和东西.希望这会有所帮助.

Simple, but works, and sometimes I target other dependency properties like font and stuff too depending on the need. Hope this helps.

PS - 您可以以相同的方式定位其他具有自己属性的 TargetType，例如 ChildWindows、Popups、Windows 等等...

PS - You can target other TargetType's with their own properties the same way, like for example, ChildWindows, Popups, Windows, whatever...
