Tab Control

Question

I have added a tab control to a win user form but the tabs will not display text!  I have the tab named tbctrl1 and I tried double clicking the form and adding in

        private void tbctrl1_Click(object sender, EventArgs e)

        {

                tbctrl1.Text = "This is Tab 1";

        }
but it continues to show a blank tab with no text for the name.  Did I place the naming code in the wrong location?  Or am I naming the tab the wrong way?
