So like above video, below's cards does not shown. Until I click with mouse left inside that scrollview area.

How can I make it shown at first without the need of mouse click?

Here is code.

1. public void MakeBattleHand()
2.     {       //Make user's hand's card when battle mode
3.         foreach (CardBase cd in HandCardClass)
4.         {
5.             AddCardToBattleHand(cd);
6.         }
7.     }
8.     public void AddCardToBattleHand(CardBase cd)
9.     {
10.         GameObject go = Instantiate(cardPref);
11.         AdvenUI.Instance.MoveObjToNGUITransform(go, handGridBat);
12.         go.GetComponent<CardPreScript>().thisCard = cd;
13.         go.name = cd.name;
14.         MakeCardInfo(go, cd);
15.         handScrollBat.transform.localPosition = new Vector3(0, 0, 0);
16.         handScrollBat.UpdateScrollbars(true);
17.     }
18. ............
19. public void MoveObjToNGUITransform(GameObject go,  UIGrid grid)    
20.     {
21.         if (go == null)
22.             return;
23.         go.transform.parent = grid.transform;
24.         go.transform.position = CardManager.Instance.Tf_UI_Root.transform.position;
25.         go.transform.localScale = new Vector3(1f, 1f, 1f);
26.         go.transform.localRotation = Quaternion.identity;
27.         grid.Reposition();
28.         grid.repositionNow = true;
29.         grid.transform.parent.GetComponent<UIScrollView>().ResetPosition();
30.         NGUITools.MarkParentAsChanged(go);
31.         grid.transform.parent.localPosition = new Vector3(0, 0, 0);
32.         SetCard.Instance.ShowDeckNum();
33.     }
34.  
35.

You are changing the transform's parent, but never notify the NGUI that this happened.

Use NGUITools.MarkParentAsChanged(gameObject)

I called  NGUITools.MarkParentAsChanged(go);  already in my second function.

Ah, sorry guess I missed that. Should work then. If nothing else, just try calling NGUITools.ImmediatelyCreateDrawCalls on your panel at the very end.
