Wpf 将TextBox的BorderBrush动态应用于边框的BorderBrush

我的应用程序中有

textboxs

和

FakeTextBoxes

faketextbox

充当

textbox

，但它们有更多的功能，因为它们里面有按钮和/或图像

XAML

用于

FakeTextBox

的外观如下：

                <Border BorderThickness="1">
                    <StackPanel Orientation="Horizontal">
                        <TextBox BorderThickness="0" />
                        <Button>I'm a button inside textbox</Button>
                    </StackPanel>
                </Border>

我是文本框中的一个按钮

我的项目中的

TextBox

具有自定义样式，可根据其

IsMouseOver

和

GotFocus

属性更改其

BorderBrush

。通用样式来自mahapps.metro，您可以在此处找到：

问题是我不能对我的

FakeTextBox

的边框应用相同的行为。我希望在我的自定义

边框上具有完全相同的行为，以便它看起来与其他
文本框
完全相同

我在
Border
中尝试过但没有成功的内容：


绑定到内部
文本框的
BorderBrush
属性

绑定到
TextBox
的
IsFocused
属性：IsFocused没有setter
创建隐藏的
文本框
并绑定到其
边框笔刷

有一个通用和/或简单的解决方案吗？
既然您想复制边界行为，让我们在en中查找边界笔刷的实现方式。找到三个，去拿钥匙，去参观一下


#FF000000
#FF7F7F
#FFCCCC
我是文本框中的一个按钮

IsFocused BorderBrush很棘手，因为它是文本框的IsFocused属性。如果做得好，您可能希望在边框上声明一个IsFocused，并将其绑定到文本框的IsFocused，或者将其全部设置为自定义边框。
我在这方面遇到了无数问题

我的解决方案是创建三个不同的边界


FocusBorder
MouseOverBorder
NormalBorder

 <代码> FocusBorder <代码>停留在顶部，<代码> MouseOverBorder <代码>停留在中间层，<代码> NormalBorder <代码>在最低级。
FocusBorder
的可见性由
Control.GotFocus
和
Control.LostFocus
事件触发器决定。对于
Control.MouseEnter
和
Control.MouseLeave
事件，MouseOverBorder的行为相同

FakeTextBox

是否源自

文本框

？你也可以显示自定义文本框样式吗？实际上不是。它只是视图/用户控件中的一个代码段。这是文本框的自定义样式。你能给我们看一下组成FaketTextBox的代码（xaml）吗？谢谢你，芬克，我想我会选择这种方式。只是一个问题：我将

改为=“白色”

改为

改为=“{StaticResource BlackColor}”

它不起作用

BlackColor

在

MahApps

中定义，但：\。有什么想法吗？编辑：我刚刚意识到，这段代码会更改WPF视图中每个边框的颜色，尽管我只想更改

FakeTextBox

@U.Bulle的边框。该样式仅应用于外部边界。对于要应用于所有实例的样式，必须在参考资料中声明它。您所经历的是，Border.Resources中的颜色键被覆盖。你可以一个接一个地把它们拿出来，看看会发生什么。
