Expression Blend 设计时特定的视觉效果是否可能？
我正在尝试在 Blend 3 中设计一些 UserControl 类。我希望它们的一部分在运行时创建时“折叠”，但我希望能够编辑它们的组成部分，而无需每次构建时都修改代码。
它适用于示例数据源，如以下示例所示。但它似乎不适用于其他属性......或者我做错了什么？
通过示例数据源SDS_AIVertexAction，我们可以在 Expression Blend 中执行此操作：
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
...>
<Grid x:Name="LayoutRoot"
d:DataContext="{Binding Source={StaticResource SDS_AIVertexAction}}" >
...
</Grid>
但似乎不可能做到这一点：
<Label Content="{Binding Name}" Visibility="Collapsed" d:Visibility="Visible" />
我意识到我可以更改“加载时”的可见性，但我真的不想每次制作这样的控件时都输入所有这些废话。有人知道让我们这样做的秘密吗？
I'm trying to design some UserControl classes in Blend 3. I want parts of them to be "collapsed" when created at runtime, but I want to be able to edit their component parts without fiddling with code every time I want to build.
It works with sample datasources, as the following example illustrates. But it doesn't appear to work with other properties... or am I doing something wrong?
With a sample data source SDS_AIVertexAction We can do this in Expression Blend:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
...>
<Grid x:Name="LayoutRoot"
d:DataContext="{Binding Source={StaticResource SDS_AIVertexAction}}" >
...
</Grid>
But it does not seem to be possible to do this:
<Label Content="{Binding Name}" Visibility="Collapsed" d:Visibility="Visible" />
I realise I could change visibility "on loaded" but I'd really rather not type all that guff every time I make a control like this. Does someone know a secret that lets us do this?

嗯，这是一个猜测。
d: 命名空间用于在设计时受到尊重但在运行时被忽略的内容。因此，我们希望在 d: 命名空间内以某种方式设置可见性，它会覆盖运行时设置的可见性。
内联样式会覆盖全局设置或通过 StaticResource 设置的样式，因此我建议这样做（从内存中 - 不要只是复制和粘贴它，而是理解概念）：
Well, here's a guess.
The d: namespace is for stuff that is respected at design time but ignored at runtime. So we want to set the visibility somehow within the d: namespace where it overrides visibility set for runtime.
Inline styles override styles set globally or via StaticResource, so I'd suggest doing this (from memory--don't just copy and paste it, understand the concept):
