How to add a control to a panel in a form from another user control

I have form1.cs, and in this form I have panel1, in the load event of form1.cs I add a control to panel1. Now my problem is: I have an element called Numbers.cs, I need to add another control to this panel1, but from this control to the button event. How can i do this?

public partial class Number : UserControl
{
    public Number()
    {
        InitializeComponent();
    }

    private void btnAcceptWelcome_Click(object sender, EventArgs e)
    {
          //HERE I NEED TO PASS A CONTROL TO THE PANEL1 IN FORM1.CS
          //NOT SURE HOW TO DO THIS.
    }
}
