Scrollbar is not appearing in my list, I am using Unity 4.6

void OnGUI() {

scrollPosition = GUILayout.BeginScrollView(scrollPosition, GUILayout.Width(400), GUILayout.Height(250));

    for (int i = 0; i < ItemList.Count; i++) {
    GUI.Label(new Rect(BoxTile.x, (BoxTile.height * i) + BoxTile.y + BoxTile.height, BoxTile.width, BoxTile.height), ItemList*.Title, style );*

GUI.Label(new Rect(BoxDes.x, (BoxDes.height * i) + BoxDes.y + BoxDes.height, BoxDes.width, BoxDes.height), ItemList*.Description, style );*
GUI.Label(new Rect(BoxCost.x, (BoxCost.height * i) + BoxCost.y + BoxCost.height, BoxCost.width, BoxCost.height), ItemList*.Cost, style );*
if (GUI.Button(new Rect(BoxBtn.x, ((BoxBtn.height+15) * i)+ BoxBtn.y + BoxBtn.height+15, BoxBtn.width, BoxBtn.height), “x” )) {
ItemList.RemoveAt(i);
}
}
GUILayout.EndScrollView();}
I am trying to create a list of item where it will just keep expanding using GUIlabel, then I can use a scroll bar to scroll through the list of items in Unity Script vertically by using C#. However, it seemed like the scroll bar will not appear on my list.
With my limited knowledge in Unity, I am not sure how to make modification on this codes to show the scrollbar, can someone please show me some light on this? Thanks in advance.

Just use the 4.6 UI Scrollbar.

1). right click in hierarchy

2). go to UI > Canvas (creates new canvas)

3). right click on the newly created ‘Canvas’ go to UI > Scrollbar
