VB.NET MDI Children 仅关注标题栏单击
人们可能会想象，单击 MDI 子窗体（或任何控件）中的任意位置都会聚焦该窗体。但在我的应用程序中，我只能通过单击其标题栏来聚焦 MDI 子项，这是用户的异常行为。我的表单充满了控件或面板，因此我无法仅仅“单击表单”。但单击其中的任何位置都应该将其聚焦。
尽管其他人似乎也遇到了这个问题，但我一直无法找到解决方案。
One would imagine that clicking anywhere within the MDI Child form (or on any control) will focus that form. But in my application I can only focus a MDI child by clicking on its titlebar, which is an abnormal behavior on the part of the user. My forms are filled with either controls or panels so I don't have the luxury of just "clicking on the form." But clicking anywhere within it should focus it.
I haven't been able to find a solution to this problem although it seems others are having it as well.

我想通了。如果您在调用
Form.Show之后设置子表单mdiParent属性，那么它会扰乱所有子表单的焦点。当我首先设置表单的
mdiParent属性然后调用.Show()时，一切都按预期完美运行。I figured it out. If you are setting the child form
mdiParentproperty after you are callingForm.Showthen it messes up the focus of all the child forms.When I set
mdiParentproperty of the form first and then call.Show(), everything works perfectly as expected.
