如何在窗体应用程序的控件中嵌套控件

问题描述：

我想在另一个窗口中嵌入一个窗体应用程序。我可以在form1中嵌入form2进行一级嵌入。但是我想在form2中嵌入第三种形式，例如form3（它本身嵌入在form1中）。当我点击form2菜单条项时，它什么也没做（可能因为form3嵌入其中？）。

我该如何解决这个问题？

我尝试过：

I want to embed a window form app within another. I can do a one level embed from say embedding form2 in form1. However I want to embed a third form say form3 within form2(which is itself is embedded within form1). When i click the form2 menu strip item it does nothing(perhaps because form3 is embedded within it ?).
How can I solve this please?

What I have tried:

            var f2 = new Form2();//Within Form1
            f2.TopLevel = false;
            f2.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            f2.Size = this.Size;
            f2.BringToFront();
            f2.Visible = true;
            this.Controls.Add(f2);

var f3 = new Form3();//Within form2
            f3.TopLevel = false;
            f3.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            f3.Size = this.Size;
            f3.BringToFront();
            f3.Visible = true;
            this.Controls.Add(f3);

答

您显示的代码没有在Form2中嵌入Form3 - 它将它与Form2一起嵌入Form1中。如果我简化你的代码：

The code you show doesn't embed Form3 inside Form2 - it embeds it in Form1 alongside Form2. If I simplify your code:

var f2 = new Form2();
...
this.Controls.Add(f2);

var f3 = new Form3();
...
this.Controls.Add(f3);

您需要做的是：

What you would need to do is:

var f2 = new Form2();
...
this.Controls.Add(f2);

var f3 = new Form3();
...
f2.Controls.Add(f3);
