checkbox - 我可以更改 LongListMultiSelector 中的 CheckBox 颜色吗？ WP8

Question

我需要更改 Windows Phone 8 中 LongListMultiSelector 的复选框的颜色，因为我的背景是白色，这可能吗？

谢谢。

Answer 1

为此，您必须首先通过在 visual studio 中的文档大纲中右键单击 longlistselector 来编辑 ItemContainerSyle，然后选择“编辑其他样式”->“编辑 ItemContainerSyle”->“创建空”

然后您必须将生成的模板的 setter 替换为来自 codeplex 的原始 setter 代码。

以下 setter 代码使复选框居中，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，但内部的实际勾号仍为白色(因为它们继承自移动设备的资源)。

您可以使用相同的方式编辑复选框样式。 以下代码将使勾号变为灰色:
