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:

C#

            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);

Solution 1

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

C#

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

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

What you would need to do is:

C#

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

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

I've tried to apply the fix you proposed but it doesn't get the job done. How can f2.controls.add (f3) be called in form1.? I was under form2 when the code
var f3= new Form3 ();
......
This. Controls.add (f3)
Was written. When I call the variables you advice be called from form 1 it superposes them controls on the same form
