accessing the text in a textbox from a usercontrol

Hello,
 
i have a usercontrol which is added to my main form via a click button event.
Each time the button is clicked a newbox is added and a counter called "nextbox" is incremented. Does any one know how to get the text from the textboxes within the usercontrol? It seems like it should be easier than it is. The two textboxes within the usercontrol have their modifiers set to public.
Regards.
 

// *** Add New Box ***

        private void button2_Click(object sender, EventArgs e)
        {
            newBox box = new newBox();
 
            if (newBox1.textBox1.Text == "0")
            {
                MessageBox.Show("Please Enter Length!");
            }
 
            {
                draw = true;
                box.BringToFront();
                box.Location = new System.Drawing.Point(panel1.AutoScrollPosition.X + boxXcoord, panel1.AutoScrollPosition.Y + boxYcoord);
                box.TabIndex = nextBox;
                panel1.Controls.Add(box);
                boxYcoord += newboxcoord;
                box.Name = nextBox.ToString();
                nextBox++;
 
                length = box.textBox1.Text;
 
                angle = box.TextBox2.Text;
 
                lineClass.sideLengthA = double.Parse(length);
                lineClass.angleInDegs = double.Parse(angle);
                lineClass.angleInRads = (Math.PI*(lineClass.angleInDegs+90)/180);
 
                MessageBox.Show("Length = " + length.ToString());
                MessageBox.Show("Angle = " + angle.ToString());
                
                Xdestin = (Convert.ToInt32(sideA * Math.Sin(lineClass.angleInRads)) + Xorigin);
                Ydestin = (Convert.ToInt32(sideA * Math.Cos(lineClass.angleInRads)) + Yorigin);
                
                panel2.Refresh();
            }
