我使用上面的代码删除了工具箱中的PhoneTextBox的背景色，一切都很好，但是没有出现提示。应用此样式后。如果有人帮助我，我将不胜感激。

根据您的需要，我刚刚为PhoneTextBox创建了样式，并为其应用了此样式。背景在正常和聚焦状态下都是透明的。

<Style x:Key="PhoneTextBoxStyle1" TargetType="toolkit:PhoneTextBox">
        <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>
        <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>

        <Setter Property="SelectionBackground" Value="{StaticResource PhoneAccentBrush}"/>
        <Setter Property="SelectionForeground" Value="{StaticResource PhoneTextBoxSelectionForegroundBrush}"/>
        <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
        <Setter Property="Hint" Value="sample"/>

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

最后，将以下代码添加为提示样式。

<Style TargetType="ContentControl" x:Key="HintCustomStyle">
        <Setter Property="FontFamily" Value="Calibri"/>
        <Setter Property="Foreground" Value="Aqua"/>
        <Setter Property="FontSize" Value="30"/>
    </Style>

如果要自定义提示样式，请更改HintCustomStyle。
