Answer 1

I improved/fixed my extension method.

public  static class ControlsExtensions
{
    public static void ClearControls(this Control frm)
    {
        foreach (Control control in frm.Controls)
        {
            if (control is TextBox)
            {
                control.ResetText();
            }

            if (control.Controls.Count > 0)
            {
                control.ClearControls();
            }
        }
    }
}
