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(选中/输入时显示的背景)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 - 我是新手)。
其他(最好是更容易)选项如何做?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并给出了设计。
应用程序需要看起来与用户在手机上选择的主题相同。
由于在写入TextBox / PasswordBox时文本为白色且主题为黑色,因此背景也会变为白色 - 结果是您无法看到正在键入的内容。
更改“Foreground-when-typing”或“background-when-typing”更容易吗?如何在不重新创建整个ControlTemplate的情况下完成?
答案 0 :(得分:6)
这样做的方法是使用重新模板和隐式样式。
不要害怕。这很简单,看,这就是你所追求的:

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。)
此:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<StackPanel>
<TextBox Text="something" />
<TextBox />
</StackPanel>
</Grid>
创建此:
不幸的是,你不能使用强调颜色对选择中的句柄做任何事情。
我没有提供禁用或只读状态,但它们应该很容易改变。
