使用 DataBinding 时在 RadGrid 内显示 ListBox

Question

我创建了一个内容应用程序，它显示代表不同情况的曲目列表（目前）。它们每个都有一个目标按钮、案例编号、案例类型和日期。我正在使用 telerik:radgridview 来实现这一点，并且每一行都是可点击的。展开该行时，您会看到有关情况的更多信息。一个部分称为“响应资产”。在本节中，我想显示一个 ListBox 或任何我可以用来再次显示这些相同曲目的东西。这只是为了测试目的，稍后我会给你一组特定的数据，但我无法在此处显示任何内容。我不知道尝试在 radgrid 中显示另一个列表是否存在问题或什么？任何想法为什么这不起作用？

.xaml 代码

<telerik:RadGridView.RowDetailsTemplate>
    <DataTemplate>
        <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" Background="#303134" Name="RowDetails">

                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>

            </Grid>

    </DataTemplate>
</telerik:RadGridView.RowDetailsTemplate>

我没有提供有关如何获取 FilteredTrackList 的代码，因为这显然有效，否则我将无法在 radgrid 中单击行。

Answer 1

ListBox 的DataContext 是一个单独的Entity 对象。如果您想绑定到与父级RadGridView 绑定的相同FilteredTrackList，您可以使用{RelativeSource}：

<ListBox ItemsSource="{Binding DataContext.FilteredTrackList, RelativeSource={RelativeSource AncestorType=telerik:RadGridView}}" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0 5 0 10">
