【问题描述】：

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 DataGrids 的网格。我尝试在 Grid 和 DataGrids 上设置 height=Auto。我尝试在 Grid 和 DataGrids 上设置 HorizontalContentAlignment="Stretch"。对象标签的高度=“100%” 我在网格的 RowDefinitions 上设置了 Height="*"

任何帮助将不胜感激！

这是代码清单：

【问题讨论】：

不清楚哪个方向不适应？水平的还是垂直的？

【解决方案1】：

您似乎有过多的 RowDefinitions，您没有为 Grid.Row="1" 分配任何内容。也许您应该消除这一行并调整元素上的 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"。
