C# Adding control dynamically to a tabpage problem?!!

Hi all.

I have a windows form, and it has a tabcontrol component on it with NO ANY TABS*. There is a toolstripbutton called newToolStripButton. When i click, it automatically adds a new tabpage to tabcontrol component with a string name. The problem is, i want it to add another control to the created tabPage. I am trying to do this with the following code, which is not working :)

private void newToolStripButton_Click(object sender, EventArgs e)
        {

            tabControl1.TabPages.Add("Untitled Page");

            foreach (Control c in this.tabControl1.TabPages)
            {
                if (c is RichTextBox)
                {
                    tabControl1.Controls.Add(rtb);
                }
            }
        }

Well, everytime i add a new tabPage by clicking the new toolstrip button, the richtextbox control should be added too to the current tabpage. Can someone help me? Other solutions than foreach loop are accepted :)

 

Thanks
