有人可以告诉我为什么包装在这些文本块中不起作用吗？我只是不知道为什么，我将所有堆栈面板都更改为网格以避免无限空间问题，但它仍然不起作用......

<Border x:Name="SummaryRightSideContainerBorder" Grid.Column="1"
        Margin="10,10,10,10" BorderBrush="Black"
        BorderThickness="1">
    <ContentControl x:Name="SummaryRightSideContainerContentControl" Content="{Binding SelectedItem, ElementName=SummaryTreeView}">
        <ContentControl.Resources>
            <DataTemplate DataType="{x:Type ViewModelsProject:ProjectViewModel}">
                <StackPanel>
                    <TextBlock Text="Displaying Project DataContract stuff..." />
                </StackPanel>
            </DataTemplate>
            <DataTemplate DataType="{x:Type ViewModelsProject:SequenceViewModel}">
                <StackPanel>
                    <TextBlock Text="Displaying Sequence DataContract stuff..." />
                </StackPanel>
            </DataTemplate>
            <DataTemplate DataType="{x:Type ViewModelsProject:GroupViewModel}">

原来使这项工作的唯一方法是直接在 DataGrid 中使用属性：

MaxWidth="{Binding ElementName=SummaryRightSideContainerBorder, Path=ActualWidth}" ColumnWidth="*"

使用 MaxWidth 是为了使 Datagrid 本身不超过其容器边界，使用 ColumnWidth 是为了使列使用数据网格中可用空间的 100%。

Blam 的回答让我找到了解决方案。

作为答案，您需要将第二列设置为

<ColumnDefinition Width="*"/>

所以它受到约束。* 表示容器的大小。现在它正在容器（屏幕）之外生长

第一列自动是好的
