I tried something like this

void RemoveRecursivce(Upp::Ctrl *ctrl) {
  if(ctrl == NULL) {
    return;
  }
  for(Upp::Ctrl *_ctrl = ctrl->GetFirstChild(); _ctrl; _ctrl = ctrl->GetNext()) {
    RemoveRecursivce(_ctrl);
    if(_ctrl != NULL) {
      ctrl->RemoveChild(_ctrl);
    }
  }
}

I also tried this, It seems to remove everything but the code to add it back in does not seem to work.

void RemoveRecursivce(Upp::Ctrl *ctrl) {
  if(ctrl == NULL) {
    return;
  }
  while(ctrl->GetChildCount()) {
    Upp::Ctrl *tctrl = ctrl->GetIndexChild(ctrl->GetChildCount() - 1);
    if(tctrl->GetChildCount()) {
      RemoveRecursivce(tctrl);
    } else {
      ctrl->RemoveChild(tctrl);
    }
  }
}

If I do all of it manually. eg Call RemoveChild for each and every element in the UI it works fine. but trying to do it recursively seems to mess it up.

not sure what I am doing wrong.
