Creating Form Inside the Form

Question

I'm new to Visual Studio 2010 and I'm planning to create a Timekeeping system. I'm just want to ask how could I create a form that compose 2 forms in it. For example, if I will click a button it will open a new form inside a form. Please help. Thanks

dont nest a form inside another. you will only cause more problems — Ibu, Jun 24 '11 at 05:45
On the other hand, see [Hans Passant - turn a form into a child control](http://stackoverflow.com/a/7692113/199364). — ToolmakerSteve, May 20 '17 at 15:53

Form formA = new Form();
formA.IsMdiContainer = true;

Form formB = new Form();
formB.MdiParent = formA;
formB.Show();

You have to work with MDI (Multiple Document Interface), have alook at this article that might help.

You could create custom form, remove all borders, and toolbars to make it look as closely to a panel as possible. Then make that new custom form a MdiContainer / MDI-panel and show forms in that panel, something like the code below will do the job

Mdi-Panel definiton:

public class MdiClientPanel : Panel { private Form mdiForm; private MdiClient ctlClient = new MdiClient();

public MdiClientPanel()
{
    base.Controls.Add(this.ctlClient);
}

public Form MdiForm
{
    get
    {
        if (this.mdiForm == null)
        {
            this.mdiForm = new Form();
            /// set the hidden ctlClient field which is used to determine if the form is an MDI form
            System.Reflection.FieldInfo field = typeof(Form).GetField("ctlClient", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
            field.SetValue(this.mdiForm, this.ctlClient);
        }
        return this.mdiForm;
    }
}

}

Usage:

/// mdiChildForm is the form that should be showed in the panel
/// mdiClientPanel is an instance of the MdiClientPanel
myMdiChildForm.MdiParent = mdiClientPanel1.MdiForm;

I think, this is a very easy way:

    Form1 form= new Form1 ();
    form.TopLevel = false;
    this.Controls.Add(form);
    form.Show();

Maybe MDI interface will do what you want..
