在我们的 Windows 10 UWP 应用程序中，我们在随机页面导航期间遇到堆损坏。时间和位置总是不同的，但结果相同，打开 Native 调试时堆损坏，关闭时立即崩溃。

下面是堆损坏时的调用堆栈，其中包含我们从 Visual Studio 收集到的尽可能多的信息。

有没有人遇到过这个确切的问题或接近问题并设法解决它？提前致谢。

编辑！得到了一些新信息！可悲的是还没有修复，但进展...... :)

原来问题是由用于创建自适应界面的 VisualStateGroups 引起的，如下所示：

<Style TargetType="controls:CollectionView">
    <Setter Property="RelativePanel.AlignLeftWithPanel" Value="True"/>
    <Setter Property="RelativePanel.AlignRightWithPanel" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="controls:CollectionView">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>

                    <GridView x:Name="List" 
                              Grid.Row="1" 
                              BorderBrush="Black" 
                              ItemsSource="{TemplateBinding ItemsSource}"
                              ItemTemplate="{TemplateBinding ItemTemplate}"
                              SelectedItem="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=SelectedItem, Mode=TwoWay}"
                              ShowsScrollingPlaceholders="False"
                              Background="Transparent"
                              RelativePanel.AlignLeftWithPanel="True"
                              RelativePanel.AlignRightWithPanel="True">
                    </GridView>

                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup>
                            <VisualState x:Name="UnSelectable">
                                <VisualState.StateTriggers>
                                    **<StateTrigger IsActive="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsNotSelectable}"/>**
                                </VisualState.StateTriggers>

                                <VisualState.Setters>
                                    <Setter Target="List.Background" Value="#AAAAAA"/>
                                    <Setter Target="List.IsHitTestVisible" Value="False"/>
                                </VisualState.Setters>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

如果我禁用上述 statetrigger 应用程序不会崩溃，遗憾的是我需要此状态内的逻辑......任何可能的解决方法或解释我做错了什么？

对于您的场景，ItemContainerStyleSelector可能会解决问题，或者您可以使用ItemTemplateSelector为Datatemplate您的GridView.

这是答案中使用 ItemTemplateSelector的示例ItemsControl。
