推荐答案

public void GetControl(Control control)
    {
        //parent could be listview ..so use its id
        foreach (Control ctrl in parent.Controls)
        {

            if (ctrl.GetType() == typeof(TextBox))
            {
              //control  found  ... return here
            }
           else
           {
              GetControl(ctrl);
