EDIT

I have rewritten my solution to use reflection.

using System.Reflection;

// your TabControl will be defined in your designer
TabControl tc;
// as will your original TabPage
TabPage tpOld = tc.SelectedTab;

TabPage tpNew = new TabPage();
foreach(Control c in tpOld.Controls)
{
    Control cNew = (Control) Activator.CreateInstance(c.GetType());

    PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties(c);

    foreach (PropertyDescriptor entry in pdc)
    {
        object val = entry.GetValue(c);
        entry.SetValue(cNew, val);
    }

    // add control to new TabPage
    tpNew.Controls.Add(cNew);
}

tc.TabPages.Add(tpNew);

Answer 2

I know it's an old thread but I just figured out a way for myself and thought I should share it. It's really simple and tested in .Net 4.6.

Please note that this solution does not actually create new controls, just re-assigns them all to new TabPage, so you have to use AddRange each time you change tabs. New tab will show the exact same controls, content and values included.

// Create an array and copy controls from first tab to it.
Array tabLayout = new Control [numberOfControls];
YourTabControl.TabPages[0].Controls.CopyTo(tabLayout, 0);

// AddRange each time you change a tab.
YourTabControl.TabPages[newTabIndex].Controls.AddRange((Control[])tabLayout);

Your best bet would be to look at this article:

Code Project

Then apply the following code to add the cloned control (this would be in your button click handler code (based on article):

    private void button1_Click(object sender, EventArgs e)
    {
        // create new tab
        TabPage tp = new TabPage();

        // iterate through each control and clone it
        foreach (Control c in this.tabControl1.TabPages[0].Controls)
        {
            // clone control (this references the code project download ControlFactory.cs)
            Control ctrl = CtrlCloneTst.ControlFactory.CloneCtrl(c);
            // now add it to the new tab
            tp.Controls.Add(ctrl);
            // set bounds to size and position
            ctrl.SetBounds(c.Bounds.X, c.Bounds.Y, c.Bounds.Width, c.Bounds.Height);
        }

        // now add tab page
        this.tabControl1.TabPages.Add(tp);
    }

Then you would need to hook the event handlers up. Will have to think about this.
