How can I duplicate tabPage in c#?

I got it!

For those who has the same kind of problem, Here is what I’ve done:

I had created a UserControl (thanks a lot for @SLaks and @Brian for your tip), copied all objects from my TabControl to my new UserControl and used the follow code to create a dynamic tabs:

for (int x = 0; x < 3; x++)
{
   UserControl1 uc = new UserControl1();
   TabPage tp = new TabPage();
   tp.Controls.Add(uc);
   this.TabControl1.TabPages.Add(tp);
}

As Schabse mentioned in a comment above, I highly recommend that you do this with User Controls.
