Hi Jegan Priya,
You cant Directly add a Form inside another Form But in MDI, Because Form is a Ultimate Parent, But you can set Owner for a Form, That may help you to provide a relation between forms Like
Form1 form1 = new Form1();
Form2 form2 = new Form2();
form2.Owner = form1;

Hi Vulpe,

Yes, All solution working fine, But I need individual floating so I am choosing second one i.e., setting owner methods. Also Thank you so much

If you minimize the parent form, then it will automatically minimize the child form(s) using any of the above 3 approaches.

Hi Vulpes,

Really thanks for the help But I just want access Minimize all child while I am trying to minimize parent ? How can I do this?

Another way to do this without using MDI is to call the Win32 API function SetParent:

using System.Runtime.InteropServices;

// ....

// add this declaration within the parent form:

[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

// now use this code to open the child form within the parent:

ChildForm child = new ChildForm();
SetParent(child.Handle, this.Handle);
child.Show();

The usual way is to create a multiple document interface (MDI) application.

The parent form has its IsMdiContainer property set to true.

You can then open an MDI 'child' form from the parent with code such as this:

ChildForm child = new ChildForm();
child.MdiParent = this;
child.Show();

and the child form will appear and remain within the parent form's boundaries.
