find control in page

Question

HTML

Answer 1

This should find any Control on page

private Control FindALL(ControlCollection page, string id)
{
  foreach (Control c in page)
  {
    if (c.ID == id)
    {
      return c;
    }

    if (c.HasControls())
    {
      var res = FindALL(c.Controls, id);

      if (res != null)
      {
        return res;
      }
    }     
  }
  return null;
}

Call like:

Button btn = (Button)FindALL(this.Page.Controls, "a");
btn.Text = "whatever";
