Access controls in created TabPage from separate function C# WinForms

I have the following code in my WinForms C# app:

        private void button2_Click(object sender, EventArgs e)
        {
            var txtbox2 = new System.Windows.Forms.RichTextBox();
            TabPage createdtabpage = new TabPage("I am a tab");
            tabControl1.TabPages.Add(createdtabpage);
            createdtabpage.Controls.Add(txtbox2);
        }

And I want to access the text of txtbox2 when a separate button is clicked. I have this code:

        private void button1_Click(object sender, EventArgs e)
        {
           //Either this:
           string text = txtbox2.Text;
           //or maybe this:
           string text = createdtabpage.Controls[txtbox2]
        }

However, this code doesn't work because the variables are not accessible to outside functions.
Does anybody have a good way to access these TabPage controls from an outside function?

Thanks for any help

From the control tab, the tab is selected and then the desired control is found by name.

use this code

private void button1_Click(object sender, EventArgs e)
{           
     var textBox = (RichTextBox)tabControl1.SelectedTab.Controls["txtbox2"];
     MessageBox.Show(textbox.Text);
}

Without a name, you have to navigate through all the controls, and for example, if you have multiple richTextBox controls, know the order in which they are located.

foreach (Control control in tabControl1.SelectedTab.Controls)
{
    if(control is RichTextBox)
    {
        MessageBox.Show(control.Text);
    }
}
