C# Grabbing a Control from a UserControl that's somewhere in a MasterPage

_GetUCControl.cs

/* Function defined in a class
   Used to grab a control that's inside a UserControl
   on a page that uses a MasterPage
   App_Code\Globals.cs */

public static Control GetUCControl(string UserCtl, string Ctl)
{
  Page page = (Page)HttpContext.Current.CurrentHandler;
  MasterPage master = page.Master;
  // The UserControl is in the ContentPlaceHolder
  ContentPlaceHolder cph = (ContentPlaceHolder)master.FindControl("ContentplaceholderID");
  // Using a custom method to dig through the control hierarchy
  UserControl user_ctrl = (UserControl)FindControlRecursive(cph, UserCtl);
  Control ctrl = user_ctrl.FindControl(Ctl);

  return ctrl;
}

// Since it returns as a Control, need to cast it as the Control type expected
// Usage from page:

Label label_control = Globals.GetUCControl("UserControlID", "lblControlID") as Label;

// Now can access the control's properties

label_control.Text = "Wicked Sick 💥";

FindControlRecursive.cs

// Digs through the control hierarchy starting at a root control
// stopping when the ID matches

private static Control FindControlRecursive(Control root, string id)
{
  if (root.ID == id)
    return root;

  foreach (Control control in root.Controls)
  {
    Control child = FindControlRecursive(control, id);
    if (child != null)
      return child;
  }

  return null;
