我有一个WPF窗口，其中有两个数据绑定的列表视图。一个绑定到业务对象（我的自定义类），另一个绑定到
字典
。运行时看起来一切正常，但在输出窗口中出现错误：

即使bost ListView按预期填充了项目，但实际上在加载窗口时会导致明显的延迟

为了寻找答案，我找到了这个线程，并实现了建议的解决方案，在两个列表视图中提供了
HorizontalContentAlignment
和
VerticalContentAlignment
的默认值。这没用

                        <ListView.Resources>
                            <Style TargetType="ListViewItem">
                                <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                                <Setter Property="VerticalContentAlignment" Value="Stretch" />

    为什么我会出错？如果我显式地设置了这些对齐属性的值，为什么要将它们绑定到任何东西上呢？

    请尝试下面的内容。不确定它是否能在您的环境中工作，但这是对我有效的语法

                            <ListView.Resources>
                            <Style TargetType="ListViewItem">

                                <Setter Property="VerticalContentAlignment" Value="Stretch" />
                                <EventSetter Event="Selected" Handler="lvItemSelected" />
                            </Style>
                            <Style x:Key="GrayOutMappedColumn" TargetType="{x:Type TextBlock}">
                                <Style.Triggers>

                            <GroupStyle>
                                <GroupStyle.HeaderTemplate>

    这可能是一个数据绑定问题。你能试试吗

                            <ListView.Resources>
                            <Style TargetType="ListViewItem">

                                <Setter Property="VerticalContentAlignment" Value="Stretch" />
                                <EventSetter Event="Selected" Handler="lvItemSelected" />
                            </Style>
                            <Style x:Key="GrayOutMappedColumn" TargetType="{x:Type TextBlock}">

    您知道ListView.ItemsPanel没有关闭。我很惊讶这会编译。

    您需要覆盖默认的
    ItemContainerStyle
    。因此，布拉姆的答案有一半是正确的。这是我的：

                            <ListView.Resources>
                            <Style TargetType="ListViewItem">
                                <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                                <Setter Property="VerticalContentAlignment" Value="Stretch" />
                                <EventSetter Event="Selected" Handler="lvItemSelected" />
                            </Style>
                            <Style x:Key="GrayOutMappedColumn" TargetType="{x:Type TextBlock}">
                                <Style.Triggers>
                                    <DataTrigger Binding="{Binding Mapped}" Value="False">
                                        <Setter Property="TextElement.Foreground" Value="Black" />
                                    </DataTrigger>
                                </Style.Triggers>
                                <Setter Property="TextElement.Foreground" Value="DarkGray" />
                            </Style>
                        </ListView.Resources>
                        <ListView.GroupStyle>
                            <GroupStyle>
                                <GroupStyle.HeaderTemplate>
                                    <DataTemplate>
                                        <Border BorderBrush="LightGray" BorderThickness="0,0,0,1">
                                            <TextBlock FontSize="12" FontWeight="Bold" Margin="0,10" Text="{Binding Name}" />
                                        </Border>
                                    </DataTemplate>

                            </DataTemplate>
                        </ListView.ItemTemplate>

    为什么要使用样式设置ListView的某些属性？作为共享资源或类似资源，这将是有用的。直接在ListView元素上声明它们。我在任何XAML中都没有看到
    RelativeSource
    绑定。你能贴出来吗？这就是我要找的，但是根本没有！XAML甚至根本不包含字符串“relat”（不区分大小写），您是否解决了问题？我现在也在为同样的事情挣扎，没有luck@XMight对不起，那是两年多前的事了（还有很多其他问题）：）我简直记不起来了。好luckI，你说得对（已经有一段时间了，我不再使用该应用程序了，所以我无法验证），但我仍然想了解原因。为什么必须重写
    ItemContainerStyle
    ？那么，
    ListViewItem
    的作用是什么？当您为ListViewItem内联一个样式时，您并没有覆盖整个默认样式。我的假设是，在默认样式的某个地方，VerticalContentAlignment有一个相对资源绑定（请参见此处的默认样式示例：）。感谢您的解释。天哪，我真的不会把WPF评为程序员友好型：）在不完全了解WPF的情况下，究竟有谁会得出这样的结论：这就是原始错误消息的含义！答案被接受是的，WPF的学习曲线是荒谬的。它真的很深。我也有和OP一样的问题。在实现分组后，它开始显示在我的调试窗口中。OverridesDefaultStyle解决了这个问题
