Answer 1

你是怎么在panel中添加窗体的。

Answer 2

new 了一个窗体。
然后
testFrm..TopLevel = false;
testFrm.Dock = DockStyle.Fill;
panel.Controls.Add(testFrm);
testFrm.Show();

Answer 3

是否要用外面的 tooltip。不能用子窗体的？

Answer 4

Form2 f2 = new Form2();
f2.TopLevel = false;
f2.Visible = true;
panel1.Controls.Add(f2);可以啊。

Answer 5

就是放在子窗体的Form2.designer.cs
