c# – 在WinRT XAML中更改页面级别ListViewItem的选择颜色

我正在尝试在选择时更改ListViewItem的颜色.它的认颜色是 Windows 8紫色.

在我的App.xaml中,我可以设置以下行,这将更改整个应用程序的ListViews的选定颜色.

<SolidColorBrush x:Key="ListViewItemSelectedBackgroundThemeBrush" Color="Orange" />

但是,我想逐页进行,所以我想在页面资源中设置它.

但是,当我尝试这个时,它被忽略了,从未使用过.它似乎只适用于app.xaml.

有谁知道我怎么能绕过这个?

这适用于使用XAML和C#编写的Windows 8商店应用程序.

谢谢

解决方法

在visual studio xaml设计器中,您可以进入Outline窗口,单击树中ListView右键,单击Edit Additional Template> Edit Item Container Style> Edit a copy.
它将生成ListViewItem样式的副本,然后您可以用您想要的任何颜色替换此样式中的ListViewItemSelectedBackgroundThemeBrush.
如果只需要更改一种颜色,则可以使用Tag属性作为颜色,如果你有很多不同颜色的页面,你就不必在每个页面中都有整个样式.
这是一个例子:
ListViewItem样式使用Tag作为您在App.xaml中定义的选择颜色:
<Style x:Key="TagListViewItemStyle" targettype="ListViewItem">
        <Setter Property="FontFamily" Value="{StaticResource ContentControlThemeFontFamily}"/>
        <Setter Property="FontSize" Value="{StaticResource ControlContentThemeFontSize}"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="TabNavigation" Value="Local"/>
        <Setter Property="IsHoldingEnabled" Value="True"/>
        <Setter Property="Margin" Value="0,18,2"/>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
        <Setter Property="VerticalContentAlignment" Value="Top"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate targettype="ListViewItem">
                    <Border x:Name="OuterContainer">
                        <visualstatemanager.VisualStateGroups>

                                        </Grid>
                                    </Border>
                                    <TextBlock x:Name="MultiArrangeOverlayText" Foreground="{StaticResource ListViewItemDragForegroundThemeBrush}" FontSize="26.667" FontFamily="{StaticResource ContentControlThemeFontFamily}" IsHitTestVisible="False" Margin="18,9,0" Opacity="0" textwrapping="Wrap" Text="{Binding TemplateSettings.DragItemsCount,RelativeSource={RelativeSource Mode=TemplatedParent}}" TextTrimming="WordEllipsis"/>

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

然后在每个页面中,您只需定义一个样式:

<Style x:Key="OrangeListViewItemStyle" targettype="ListViewItem" BasedOn="{StaticResource TagListViewItemStyle}">
        <Setter Property="Tag">
            <Setter.Value>
                <SolidColorBrush Color="Orange"/>
            </Setter.Value>
        </Setter>
     </Style>

如果您需要定义多种颜色,则可以通过添加一些附加属性来使用相同的原则.
