WinForms 深层嵌套控件调整内核大小错误 - 拆分面板无法正确缩放控件

Question

（对nested 的初步猜测被证明是不正确的。问题似乎是SplitContainer 面板没有正确缩放其托管控件。）

---

我有一些表单的选项卡控件在加载时无法正确调整大小。 https://support.microsoft.com/en-us/kb/953934在 2008 年描述了这样一个内核错误。很难相信它没有得到修复。我认为它消失了一段时间，但我又开始看到问题了。

控件嵌套得很深。Midi 父、子窗体、选项卡控件、带有两个面板和控件的拆分器控件。对于自上而下的第一个有问题的控件是选项卡控件。当加载后调整窗体大小但锚点不正确并且部分控件被剪切时，它会调整大小。

该问题似乎特定于 100% 桌面字体大小 - 100+ 大小的桌面工作正常。我使用 VS 2013 v5 以 125% 的速度开发 - 这个问题也出现在 v4 上。

任何人都知道缺少知识库文章中概述的自定义控件的解决方法吗？

我错过了其他事情？

---

仔细观察 SplitContainer 是不调整锚点大小/尊重锚点的控件。

---

我尝试在显示选项卡后运行此代码但它不起作用 - 看起来与使用锚点大致相同。似乎 TabControl 报告的 ClientSize 不正确

    SplitContainer1.Width = TabControl1.ClientSize.Width - 10
    SplitContainer1.Height = TabControl1.ClientSize.Height - TabControl1.ItemSize.Height - 10

---

这是显示问题的完整表格。在 125% 桌面上，它显示为在 100% 桌面上的 IDE 中，选项卡上的控件未正确定位。

如果SplitPanel没有正确锚定其内容，您可以尝试将内容放入另一个问题较少的容器中。

尝试TableLayoutPanel在SplitPanel. 将属性设置TableLayoutPanel.Dock为Fill，然后将.Anchor您的控件设置在其中。（不要.Dock在 a 内部使用TableLayoutPanel，它有点不稳定）。

内部的控件TableLayoutPanel将具有名为.RowSpan和的新属性.ColumnSpan，该属性允许控件跨越多个单元格。

右上角有一个小箭头TableLayoutPanel，可让您编辑行和列。我发现最好的办法是制作尽可能多的固定宽度/高度，然后使用百分比来处理其余的。我没用过Autosize，不过你可以试试。
