Answer 1

You could create an extension method like the following:

public static class ControlExtensions
{
    public static IEnumerable<Control> GetAllControls(this Control containerControl)
    {
        var controls = Enumerable.Empty<Control>();
        controls = controls.Concat(containerControl.Controls.Cast<Control>());
        foreach (Control control in containerControl.Controls)
        {
            controls = controls.Concat(control.GetAllControls());
        }
        return controls;
    }
}

And use it like this:

foreach (Control c in theForm.GetAllControls())
{
    Debug.WriteLine(c.Name);
}

Note the the method GetAllControls can be used with any Control , not only with Form

If controls are not placed into a TableLayoutPanel , then they are likely to be in the main form itself. So ypu can loop through them like this:

foreach(Control control in this.Controls)
{
  //do somthing with the controls
}
