    Listv.Clear
        Try
        Dim sf As Object = Starter.mysql.ExecQueryAsync("mysql", "MY-SQL-STRING", Null)
            Wait For (sf) mysql_QueryComplete (Success As Boolean, Crsr As JdbcResultSet)
            If Success Then
                Do While Crsr.NextRow
                    'Log(Crsr.GetString("Name"))                   
                Listv_fyrirtaki.Add(CreateListItemVerktakar(Crsr.GetString("Name"), Listv_fyrirtaki.AsView.Width, 60dip), Crsr.GetString("Name"))   
                    Loop
                Crsr.Close
            End If
        Catch
            Success = False
            Log(LastException)
    End Try

hide the label after you refresh the list, then make it visible again after repopulating the listview

Is the list flashing in release mode as well as debug mode?

You could always try adding Sleep(0) or Sleep(100) after 'Listv.Clear', but that should really make no difference and map cause you another issue entirely...

CustomListView flicker in release and debug mode


can this make the CustomListView flicker

Activity_Create
I use Activity.LoadLayout("main")

CreateListItemVerktakar
Dim p2 As Panel
p2.Initialize("")
p2.SetLayout(0, 0, Width, Height)
p2.LoadLayout("mainvalUndir")

Please use [code]code here...[/code] tags when posting code.

It is best if you reproduce it in a small project with only xCustomListView.
