I have a program that dynamically creates controls when it starts, it works just fine when the code to do this is in the class of the actual form. I tried moving the code to a separate class and found that I could not use Controls.Add(). How can I add controls to the Form from a separate class? This is what I have so far:

            TextBox txtbx = new TextBox();
            txtbx.Text = "asd" + x.ToString();
            txtbx.Name = "txtbx" + x.ToString();
            txtbx.Location = new Point(10, (20 * x));
            txtbx.Height = 20;
            txtbx.Width = 50;
            Controls.Add(txtbx);

Error 1 The name 'Controls' does not exist in the current context
