【中文标题】如何使堆栈面板内的按钮展开以占用整个空间？【英文标题】：How to make buttons inside a stackpanel expand to use up the whole space? 【发布时间】：2013-05-13 12:43:11 【问题描述】：

我有一个 Windows 8 C#- xaml 应用程序。我有一个堆栈面板，其中有 6 个堆栈面板。每个堆栈面板都有 7 个按钮。所以整个事情是形成日历的 6x7 按钮。主堆栈面板放置在网格中。

现在按钮没有设置内容。在后面的代码中，这些按钮的日期被设置为内容。

我的问题是，对于不同的分辨率，网格会扩展，因此堆栈面板会展开，但里面的按钮会更小，以适应内容。我希望按钮展开以填满整个堆栈面板。主网格、其中的主堆栈面板、子堆栈面板和按钮的高度和宽度设置为 Auto..

我一直在努力实现这一目标。但徒劳无功！有什么建议吗？

编辑：

有一个主网格，其中包含 BackButtonGrid、CalendarGrid、NotesGrid 和 StatusGrid。

CalendarGrid 有一个

2 个文本框来显示一些值。

【问题讨论】：

你可以尝试把按钮放在viewbox里面，viewbox默认行为是拉伸 【参考方案1】：

对于日历，我会考虑将您的 StackPanel 替换为 Grid。 Grid 让扩展子控件变得容易。为此，创建一个 6x7 Grid 并将高度和宽度都设置为 *。这将导致它们在父容器内均匀分布空间（即使在调整大小的情况下）。当您将按钮放入每个网格单元格时，它会自动填充整个空间。

Grid's 通常在元素需要相互对齐时是可取的。如果您不关心元素是否在特定轴上排列，请使用 StackPanel。

<Grid>
   <Grid.RowDefinitions>
      <RowDefinition Height="*" />
      <RowDefinition Height="*" />
      <RowDefinition Height="*" />
      <RowDefinition Height="*" />
      <RowDefinition Height="*" />
      <RowDefinition Height="*" />
      <RowDefinition Height="*" />
   </Grid.RowDefinitions>
   <Grid.ColumnDefinitions>
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="*" />
   </Grid.ColumnDefinitions>
   <Button
      Grid.Column="0"
      Grid.Row="0"
      Content="Test"
      />
</Grid>

【讨论】：

可能还值得一提的是StackPanel 的内容即使设置为Stretch 也不会填充父容器。它试图占用最少的空间来包含控件。然而，网格可以填充父容器（在拉伸模式下）它扩展到除了 27" 之外的所有内容！网格在一个角落。我已经更新了我的整个代码。 @alfah - 是的，您需要一些逻辑来处理当顶部和底部行未完全填满时边框的外观（例如，该月在星期二结束）。我会使用Grid 来设置您的布局，但可能会在每个单元格中嵌入一个边框，该边框仅在该单元格在该月的给定日期有效时才使用BorderThickness。
