Xamarin : Get all the child controls of type<T> of a form by sending in the root control (ContentPage)

GetAllControlsOfType<T>

private static IList<T> GetAllControlsOfType<T>(Element view) where T : View
        {
            var rtn = new List<T>();
            foreach (View item in view.Descendants())
            {
                var ctr = item as T;
                if (ctr != null)
                {
                    rtn.Add(ctr);
                }
                else
                {
                    rtn.AddRange(GetAllControlsOfType<T>(item));
                }
            }

            return rtn;
        }

        // Example Usage: IList<SfTextInputLayout> inputs = GetAllControlsOfType<SfTextInputLayout>(SignUpForm); 
        // where "SignUpForm" is the x:Name property of the ContentPage
