Question

我需要在Windows Phone 8中更改LongListMultiSelector的CheckBox的颜色，因为我的背景为白色，这是可能的吗？

感谢。

Answer 1

为了做到这一点，你必须首先通过在visual studio中的文档大纲中右键单击longlistselector来编辑ItemContainerSyle，然后选择Edit Additional Style - ＆gt;编辑ItemContainerSyle - ＆gt;创建空

然后，您必须使用codeplex中的原始setter代码替换生成的模板的setter。

以下setter代码将复选框居中，然后变为灰色：

<Style.Setters>
        <Setter Property="Background" Value="{StaticResource PhoneAccentBrush}"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="toolkit:LongListMultiSelectorItem">
                    <Grid MinHeight="52">
                        <Grid.Resources>
                            <ExponentialEase EasingMode="EaseIn" Exponent="8" x:Key="ExponentialEaseIn"/>
                            <QuadraticEase EasingMode="EaseOut" x:Key="QuadraticEaseOut"/>
                        </Grid.Resources>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="SelectionEnabledStates">

现在复选框将显示为灰色，但内部的实际刻度仍为白色（因为它们继承了移动设备的资源）。

您可以做的是以相同的方式编辑复选框样式。以下代码将勾选灰色：
