我有一个带有 DataTemplate 的 ListBox。我正在尝试将列表框中所选项目的文本/前景颜色更改为白色。我已经认真尝试了 30 种不同的方法来做到这一点,我在谷歌上找到了这些方法。我只是无法让它工作。如何更改前景色?
另外,我想指出我不想依赖使用 SystemColors 的方法,因为我读到它在 .net 4.5 中不起作用,所以我不希望它在我们移动应用程序时中断某天4.5。这是我的列表框 xaml:
<ListBox Grid.Row="1" x:Name="Alerts" ItemsSource="{Binding Alerts}" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled" AlternationCount="2">
<ListBox.ItemTemplate>
<DataTemplate>

<StackPanel Grid.Row="0" Orientation="Horizontal">
