根据PresentationFramework.Aero重写WPF TextBox中的默认样式。

问题描述

我想使用Aero文本框样式，但仍要覆盖某些属性。我尝试通过以下方式实现此目的：

I want to use the Aero textbox styling, but still override some properties. I try to accomplish this by:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/PresentationFramework.Aero, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml" />
    </ResourceDictionary.MergedDictionaries>

    <Style x:Key="{x:Type TextBox}" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
        <Setter Property="Margin" Value="2" />
        <Setter Property="Padding" Value="2" />
    </Style>
</ResourceDictionary>

但是，这会导致 StackOverflowException 启动我的应用。
当我删除对PresentationFramework.Aero的引用时，此方法有效，但是我得到了默认的OS样式，这使应用程序难看。 ;）

However, this results in a StackOverflowException when starting my app.When I remove the reference to PresentationFramework.Aero, this works but I get the default OS styling, which makes the app ugly. ;)

因此，实际上：如果我想在所有文本框中覆盖某些样式，则无法获得Aero外观。如果要使用Aero外观，则不能覆盖任何样式。死锁。

So, in effect: if I want to override some style on all my textboxes I cannot get the Aero look. If I want the Aero look, I cannot override any styling. Deadlock.

有什么办法解决这个问题？

Any way to solve this?

推荐答案

似乎如果将 Style 放在较低级别的资源中，而不是放在同一ResourceDictionary中，则可以正常工作：

It seems to work if you put the Style as a lower-level resource, instead of in the same ResourceDictionary:

<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Grid.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/PresentationFramework.Aero, Version=3.0.0.0, Culture=Neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Grid.Resources>
    <Border BorderBrush="Blue" BorderThickness="3">
        <Border.Resources>
            <Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
                <Setter Property="Margin" Value="2" />
                <Setter Property="Padding" Value="2" />
            </Style>
        </Border.Resources>
        <TextBox />
    </Border>
</Grid>
