Silverlight DataGrid 无法拉伸以容纳数据源中的所有项目？

Question

我在让 Silverlight DataGrid 拉伸以容纳其数据源中的所有项目时遇到问题。 我有一个包含两个 DataGrid 的网格。 我尝试在网格和数据网格上设置 height=Auto 。 我尝试在网格和数据网格上设置 Horizo​​ntalContentAlignment="Stretch"。 对象标签的 height="100%" 我已经在网格的 RowDefinitions 上设置了 Height="*"

任何帮助将不胜感激！

这是代码清单：

您似乎有过多的 RowDefinitions，您没有向 Grid.Row="1" 分配任何内容。也许您应该消除此行并调整元素上的 Grid.Row 分配。我还建议您将最后一个 RowDefinition 的高度设置为 Auto 并从外部网格中删除 Height="Auto" 。
