C# - 奇怪的 ToolStripMenu 行为
我有一个 ToolStripMenu，它有许多子菜单。在任何给定时间，任何子菜单都可能被禁用，具体取决于程序的当前状态。
我对某个特定菜单项有疑问。我禁用了此菜单项，因此鼠标悬停时不会显示子菜单。如果我只是将鼠标悬停在该项目上，它就会按预期工作，子菜单不会出现。但是，如果我将鼠标悬停在任何其他启用的菜单项上并显示其子菜单，然后立即将鼠标悬停在禁用菜单项上，禁用的子菜单将出现，即使该项目仍处于禁用状态。正如您所期望的，菜单项呈灰色。
菜单项从未在代码中的任何位置显式启用。有人对此有什么想法吗？
I have a ToolStripMenu that has a number of sub menus. At any given time ay of the sub menus may be disabled, depending upon the current state of the program.
I have an issue with a particular menu item. I have this menu item disabled, so that the sub-menu does not show on mousehover. It works as expected if I simply hover my mouse over the item, the sub-menu does not appear. If, however, I hover my mouse over any of the other enabled menu items and have their sub menu appear, then immediately hover the mouse over the disable menu item, the disabled sub-menu will appear, even though this item is still disabled. The menu-item is greyed out as you would expect.
The menu item is never explicitly enabled anywhere within the code. Does anybody have any ideas on this?
