我做了一个DataGrid问题，它们工作得很完美，所以我认为这是解决我问题的最佳场所.

推荐答案

好吧，它可以通过2种方式完成

首先，获取子窗体的LocationChanged事件，不要让它超出主窗体的范围.

其次，将Panel添加到您的主窗体中，然后在其中添加子窗体，但是必须将子窗体的TopLevel属性设置为false.

像这样的东西

well, it can be done in 2 ways

first, grab LocationChanged event of subform and dont let it go outside the main form''s bounds.

second, add a Panel to your main form and add the subform in it but to do that you must set sub form''s TopLevel property to false.

something like this

subform.TopLevel = false;
subform.Show();
panel1.Controls.Add(subform);
