Grid layout group save order of gameobjects

Hi. I want to save in playerprefs order of LayoutElements in Grid layout group. I have 2 scripts to drag and drop UI elements.

Code (CSharp):

1. using UnityEngine;
2. public class DragOrderContainer : MonoBehaviour {
3.     public GameObject objectBeingDragged { get; set; }
4.     void Awake () {
5.         objectBeingDragged = null;
6.     }
7. }

and

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.EventSystems;
4. public class DragOrderObject : MonoBehaviour, IPointerEnterHandler, IBeginDragHandler, IDragHandler, IEndDragHandler {
5.     DragOrderContainer container = null;
6.     void Start () {
7.         container = GetComponentInParent<DragOrderContainer>();
8.     }
9.     public void OnBeginDrag(PointerEventData eventData)
10.     {
11.         container.objectBeingDragged = this.gameObject;
12.     }
13.     public void OnDrag(PointerEventData data)
14.     {
15.         // Do nothing
16.         // Apparently this interface needs to exist in order for BeginDrag and EndDrag to work,
17.         // but we don't actually have anything to do here
18.     }
19.     public void OnEndDrag(PointerEventData eventData)
20.     {
21.         if (container.objectBeingDragged == this.gameObject) container.objectBeingDragged = null;
22.     }
23.     public void OnPointerEnter(PointerEventData eventData)
24.     {
25.         GameObject objectBeingDragged = container.objectBeingDragged;
26.         if (objectBeingDragged != null && objectBeingDragged != this.gameObject)
27.         {
28.             objectBeingDragged.transform.SetSiblingIndex(this.transform.GetSiblingIndex());
29.         }
30.     }
31. }

How can i simple save order somethink like that ?

Code (CSharp):

1. using System.Collections;

8. {
9.  
10.  
11.     public GameObject[] panel;
12.  
13.     void Awake()
14.     {
15.         for (int i = 0; i < panel.Length; i++)
16.         {
17.  
18.             panel[i] = PlayerPrefs.transform.GetSiblingIndex(panel[i].name);
19.         }

22.  
23.  
24.     private void OnApplicationQuit()

27.  
28.         for (int i = 0; i < panel.Length; i++)
29.         {
30.             PlayerPrefs.transform.SetSiblingIndex(panel[i].name, panel[i]);
31.  
32.         }
33.     }
34.  
35.  
36.     private void OnApplicationPause(bool pause)
37.     {
38.  
39.  
40.  
41.  
42.         for (int i = 0; i < panel.Length; i++)
43.         {
44.             PlayerPrefs.transform.SetSiblingIndex(panel[i].name, panel[i]);
45.             PlayerPrefs.Save();
46.  
47.         }
48.  
49.
