(最初对 nested 的猜测被证明是不正确的。问题似乎是 SplitContainer 面板无法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。很难相信它还没有被修复。我认为它消失了一段时间，但我开始再次看到问题。
控件嵌套得很深。 Midi 父窗体、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。当表单在加载后调整大小但 anchor 不正确并且部分控件被剪裁时，它会调整大小。
该问题似乎特定于 100% 桌面字体大小 - 具有 100+ 大小的桌面可以正常工作。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工作吗？
还有什么我错过了？
更仔细地观察它，SplitContainer 是不调整大小/尊重 anchor 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 anchor 大致相同。似乎 TabControl 报告了不正确的 ClientSize
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，它在 IDE 中显示为 100% 桌面上的选项卡上的控件未正确定位。

最佳答案
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错误较少的容器中。
试着把 TableLayoutPanel里面SplitPanel .设置TableLayoutPanel.Dock属性(property)给 Fill ，然后是 .Anchor你在里面的控件。 (不要在 .Dock 中使用 TableLayoutPanel ，这有点不稳定)。TableLayoutPanel 中的控件将有名为 .RowSpan 的新属性和 .ColumnSpan这允许控件跨越多个单元格。TableLayoutPanel 的右上角有一个小箭头这将允许您编辑行和列。我发现最好的办法是制作尽可能多的固定宽度/高度，然后使用百分比其余部分。我不使用 Autosize但你可以试试。
