Trying to populate a draggable list by code yields to giant Content

[laurentl]

Out of an array I instantiate Draggable Content one by one and parent them under a grid. The grid is under the Draggable Panel.
When I do this process by hand the draggable content lines up properly and preserves its dimensions.
When I do it in Start however the elements are about 100x their size.
It seems I need to trigger some calculation by hand to resize these elements properly, I tried grid.Reposition and it doesn't change a thing.

What's the secret sauce ?

1.         [System.Serializable]
2.         public class Decal
3.         {
4.                 public string name;
5.                 public Texture decal;
6.                 public DraggableButton draggableButton;
7.         }
8.        
9.         public List<Decal> decals;
10.        
11.         public DraggableButton buttonPrefab;
12.         public UIGrid gridParent;
13.        
14.         void Start ()
15.         {
16.                 for (int i=0; i<decals.Count; i++) {
17.                         Decal d = decals [i];
18.                         GameObject dg = (GameObject)Instantiate (buttonPrefab.gameObject);
19.                         dg.name = "item " + i.ToString ();
20.                         dg.transform.parent = gridParent.transform;
21.                         d.draggableButton = dg.GetComponent<DraggableButton> ();
22.                         // init the butten
23.                         d.draggableButton.SetDecal (d.decal);
24.                         d.draggableButton.SetName (d.name);
25.                         d.draggableButton.SetCallBack (gameObject, "ChooseDecal");
26.                 }
27.                 gridParent.Reposition ();
28.         }

Never use Instantiate. Use NGUITools.AddChild.

Perfect! simplifies code.

And it seems I still need to
Reposition () the grip and Recenter the UICenterOnChild
