Listview FastScrollEnabled doesn't work

[coslad]

Hi
first , excuse my bad english.
I'am here to ask you help , i'm going crazy becouse the FastScrollEnabled doesn't wants to work.

This is a test program and if you run it you'll see that even thought the FastScrollEnabled is = true the scroll button doesn't appear , where i wrong ?
In this example i use the lista array to create a master of what the listview will be , so before i load the lista array and after i will transfer the arrya to the listview :


Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.
Dim Lista_Modelli As ListView
Dim Bitmap_Sbs As Bitmap
Dim lista (30,3) As String
Dim indice_modelli As Int
Dim ListView1 As ListView
End Sub

Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("selezione_modello")
Lista_Modelli.TwoLinesAndBitmap.Label.TextColor= Colors.black
Lista_Modelli.ScrollingBackgroundColor=Colors.Transparent
Lista_Modelli.TwoLinesAndBitmap.secondLabel.TextColor= Colors.black
Lista_Modelli.FastScrollEnabled=True

carica_lista

End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub


Sub carica_lista
Dim t As Int

indice_modelli=0
lista (indice_modelli,0)="RS"

lista (indice_modelli,0)="RT60"
lista (indice_modelli,1)="TIPO3"
lista (indice_modelli,2)="button.gif"


' Carica listview
For t=0 To indice_modelli
Bitmap_Sbs.Initialize(File.DirAssets, lista (t,2))
Lista_Modelli.AddTwoLinesAndBitmap(lista (t,0),lista (t,1),Bitmap_Sbs)
Next


End Sub

It seems that if you have less than 32 items in the ListView the fast scroll function is not active.

Best regards.

Thanks

I found it by testing.
I didn't see it either in any documentation.
I suppose that it's how Android does manage it.

Best regards.
