无法将“Style”类型的值添加到“UIElementCollection”类型的集合或字典中

Question

我有以下 XAML 代码。我希望列表视图中的备用行将在运行时通过代码动态填充。我正在使用以下 XAML 代码，但它给出了名为 Error8 的错误，“Style”类型的值无法添加到“UIElementCollection”类型的集合或字典中。

 <ListView Grid.Column="1" Grid.Row="10" BorderBrush="#FFA8CC7B" Height="133" HorizontalAlignment="Left" Margin="0,0,0,93" Name="lstViewAppsList" VerticalAlignment="Top" Width="596"
              ItemContainerStyle="{StaticResource alternatingStyle}" AlternationCount="2">
        <ListView.View>
            <GridView>
                <GridViewColumn  Header="Apps" Width="150" />
                <GridViewColumn  Header="Package" Width="350" />
            </GridView>
        </ListView.View>
    </ListView>

    <Style x:Key="alternatingStyle" TargetType="{x:Type ListViewItem}">
        <Style.Triggers>
            <Trigger Property="ItemsControl.AlternationIndex" Value="0">
                <Setter Property="BValue="LightSkyBlue"></Setter>
            </Trigger>
            <Trigger Property="ItemsControl.AlternationIndex" Value="1">
                <Setter Property="Background" Value="LightGray"></Setter>
            </Trigger>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Background" Value="Orange"/>
            </Trigger>
        </Style.Triggers>
    </Style>

Answer 1

它需要ResourceDictionary某种形式，您可以添加到ListView资源Window/Page或什至外部资源文件

<ListView.Resources>
   <Style x:Key="alternatingStyle" TargetType="{x:Type ListViewItem}">
       ......
   </Style>
<ListView.Resources>

因此，将其添加到上面的示例中

<ListView Grid.Column="1" Grid.Row="10" BorderBrush="#FFA8CC7B" Height="133" HorizontalAlignment="Left" Margin="0,0,0,93" Name="lstViewAppsList" VerticalAlignment="Top" Width="596" AlternationCount="2">
    <ListView.Resources>
       <Style TargetType="{x:Type ListViewItem}">
           ......
       </Style>
    <ListView.Resources>
     <ListView.View>
         <GridView>
             <GridViewColumn  Header="Apps" Width="150" />
             <GridViewColumn  Header="Package" Width="350" />
         </GridView>
     </ListView.View>
</ListView>
