C# WinForms TableLayout赢得'；缩小规模

直截了当地问

---

资料: 我制作了这个自定义用户控件（称为ExpansivePanel），其中包含以下内容：

- TableLayoutPanel (Call it ProblemTable)
    - Label (C0, R0)
    - Button (C1, R0)
    - Panel (C0, R1, CSpan2)

单击按钮时，面板展开/折叠以显示内容

---

问题: 问题是，当我将其作为控件添加到另一个容器中并尝试调整其大小时，扩展面板下的操作都是正确的，但从问题表开始，只有当新大小大于当前大小时，它才会调整大小，当然，它的内容也不会调整大小，除非其大小在增长。 这在Linux上发生。在Windows上，只有当用户设置的大小太小时才会发生这种情况

---

我已经尝试过的事情：

• 在ProblemTable上设置Anchor而不是Dock（+将大小设置为ExpansivePanel本身，这在使用Anchors时是必需的），实际上不会改变任何东西
• 正在删除ProblemTable上的Dock（Fill）属性，这会使表的大小变小（并且已修复！），但它的内容仍然很大并且位于它下面
• 在ExpansivePanel上将Autosize设置为true，这会强制其大小为0，即使其内部有容器和控件
• 在ProblemTable上将Autosize设置为true，这根本不会影响任何内容
• 将ExpansivePanel和ProblemTable上的AutosizeMode设置为不同的值不会改变任何内容。（因为这里不能自动调整大小！）
• 。。。还有一些我不记得的事情，因为我已经两天都在想这个问题了

---

详细资料： 我正在使用Ubuntu 16.04（MonoDevelop+Mono/.NET4.0）和Windows10（MonoDevelopUnity+Mono/.NET4.0）来构建和运行这个东西。这些都发生在Linux上，但在Windows上似乎没有问题，除非用户给出的大小太小，我认为这可能是自然的！是吗

以下是ExpansivePanel的构建方法（包含一些调试代码！）：

下面是ExpansivePanel的父级的构建方法，它包含一个TableLayoutPanel容器，并将3个ExpansivePanel（Pnl_名称等）添加到它的表中。（构建不完整-包含一些调试代码！）：

截图：

• 初始状态。（i.stack.imgur.com/uOhWC.png）还没有发生任何事情。只是构建方法

• 表格的内容隐藏在它下面。其大小不变的是ProblemTable（ExpansivePanel中的aka.Cnt_MainTable）

• 表格会调整大小，其内容也会调整大小以适应表格大小。这里没有问题

• 第二次裁员。（i.stack.imgur.com/m47uH.png）自上次增长以来，表不会调整大小，但它的父表会调整大小，使表隐藏在其父表之下

这与Mono有什么关系？标记已删除。正如我所提到的，我在Linux和Windows上都使用Mono编译了它。对不起，没有看到。祝Mono上的WInForms好运。这与Mono有什么关系？标记已删除。正如我所提到的，我在Linux和Windows上都使用Mono编译了它。对不起，没有看到。祝Mono上的WInForms好运。
