在XAML中设置TextBox/PasswordBox样式

Question

我一直想知道是否有更简单的方法来更改一个属性,然后在Windows Phone 8中重新整理整个ControlTemplate.

我最近发现自己需要更改PasswordBox的背景(选择/键入时显示的背景)而不更改任何其他内容.我知道有一种方法可以重新创建整个ControlTemplate(因为它对我的品味来说很大,而且我有点迷失它 - 我是一个新手).

其他(最好更容易)的选择是如何做到的？如果是这样,哪个？

我问的原因是因为我正在创建需要在Android,iOS和Windows Phone上看起来几乎相同的应用程序(Android和iOS应用程序由其他人完成,我正在使用WP App并且设计是给出).

应用程序需要在用户的手机上查看用户选择的主题的相同方面.

由于文本是白色的,并且在写入TextBox/PasswordBox时是黑色主题,因此背景也会变为白色 - 结果是您无法看到您正在键入的内容.

更改"前台打字时"或"打字后背景"更容易吗？如何在不重新创建整个ControlTemplate的情况下执行此操作？

Answer 1

这样做的方法是重新模板化和隐式样式.

不要害怕.这很容易,看,这是你要追求的:

            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
</phone:PhoneApplicationPage.Resources>

现在,每当在该页面上使用TextBox时,它将始终是黑色背景上的白色文本.(或者在选择时反转.)

这个:

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
    <StackPanel>
        <TextBox Text="something" />
        <TextBox />
    </StackPanel>
</Grid>

创建这个:

不幸的是,你不能对使用强调色的选择上的句柄做任何事情.
