（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。很难相信它还没有得到修复。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锚点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。

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。

尝试TableLayoutPanel在SplitPanel. 将TableLayoutPanel.Dock属性设置为Fill，然后.Anchor在其中设置控件。（不要.Dock在 a中使用TableLayoutPanel，它有点片状）。

内部的控件TableLayoutPanel将具有调用的新属性.RowSpan，并.ColumnSpan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，然后使用百分比其余部分。我没用过Autosize，你可以试试。
