WPF 网格内容不跨越整个宽度答案

摘要

为了让未来的读者更清楚，这里是问题及其解决方法的摘要。

我的网格位于一个页面中，该页面用作 tabitem 的内容。在运行时，网格拒绝填充整个 tabitem 区域，如下面的屏幕截图所示。

问题在于 tabitem 的样式包含一个内容模板，该模板通过 contentpresenter 显示页面，内部是一个水平堆栈面板。堆栈面板覆盖了页面中网格的拉伸属性。

解决方案是用网格替换样式中的堆栈面板。没有更多的布局问题。

原始问题

我有一个 StackPanel，在网格内有一个标签和文本框，我想将文本框的宽度绑定到网格中前两列的宽度。我通常使用将文本框宽度绑定到其父级的方法，并尝试将 that 值绑定到具有正确值的 something，但我尝试直接绑定也是如此，没有运气。

这是我的 xaml：

我已经从各种问题和其他网站尝试了几种推荐的解决方法，但没有任何效果。我尝试在要绑定的单元格上粘贴边框并绑定到其尺寸，使用标签，嵌套另一个网格，x：命名 ColumnDefinition 并绑定到 ActualWidth 等等。没有。作品。

这似乎在 wpf 中应该非常简单，而我只是缺少关键的、次要的部分。我在这件事上大概浪费了三个小时。我做错了什么？

编辑：

我刚刚意识到我似乎绑定到整个 GridMainContent 的宽度 - 我没有。这只是一种虚拟值，已被我尝试过的每种不同的解决方案所取代。

这是我的问题的图片。内容应填满整个选项卡。请注意，周围网格的大小 down 以适合内容，而不是内容大小 up 以适合网格。我已经为我的内容定义了在每个父元素上设置 HorizontalAlignment=Stretch 的隐式样式，但似乎没有任何效果。

我期望它做的是让左侧部分（带有下拉菜单）和右侧部分（带有销售代表等）的宽度相等，填充选项卡的整个内容区域。

【问题讨论】：

尽量避免绑定，使用 WPF 布局。
这是不可接受的。我需要宽度与其父宽度正确缩放。
给你的网格孩子 Grid.ColumnSpan = 4 有什么问题？
我需要其他元素来占据剩余的列。也许我误解了你的问题。
你能用实际的绑定源更新你的 XAML 吗？

【解决方案1】：

尝试将下面的 xaml 粘贴为 WPF 窗口内容，不要使用制表符 - 我已经这样做了，布局很好：

您能否确认布局是否正确？我最好的选择是 - 根网格的父级以某种方式限制了可用空间，因此可用宽度小于屏幕宽度。检查所有可用空间是否都用石灰粉刷。

我终于找到了问题的原因并纠正了它，感谢这个答案排除了我的本地标记的问题。我认为，这对每个人都是有用的策略。
