    TableView2 library extends TableView and adds support for action buttons.
    The reason for the new library is that TableView2 requires iOS 8+.
    You can download it here:


    Action buttons can be added items with TableCell.AddActionButton.
    The buttons are revealed with a swipe.

    The ActionButtonClicked event is raised when the user clicks on one of the buttons.

    A complete example:
    Sub Process_Globals
    Public App As Application
    Public NavControl As NavigationController
    Private Page1 As Page
    Private TableView1 As TableView
    End Sub

    Private Sub Application_Start (Nav As NavigationController)
       NavControl = Nav
       Page1.Title = 
    "Page 1"
       Page1.RootPanel.Color = 
    For i = 1 To 1000
    Dim tc As TableCell = TableView1.AddSingleLine($"Item #${i}"$)
    "Change Value"Colors.Green)
    End Sub

    Private Sub TableView1_ActionButtonClicked (SectionIndex As Int, Cell As TableCell, Text As String)
    Select Text
    Case "Delete"
           TableView1.RemoveCells(SectionIndex, TableView1.GetItems(SectionIndex).IndexOf(Cell), 
    Case "Change Value"
    Dim s As AttributedString
    "New Value"Font.DEFAULT_BOLD, Rnd(Colors.Black, Colors.White))
           Cell.Text = s
    End Select
    End Sub

    Private Sub Page1_Resize(Width As Int, Height As Int)
    End Sub

    Maybe using the opportunity of xreating new lib for TableView you could also add the wishes ))
    Animation for inserting, removing. And custom accessory views.

    Note that this is not a new library. The new version is only because of the iOS 8 requirement. Custom accessory views can be easily implemented with custom views.

    Inserting and removing items actions are animated. I guess that you mean that you want to explicitly choose the animated instead of the automatic mode.

    Yes, correct.

    Regaring the custom accesoryviews it is much easer to add just one more function (uitableviewCell.accessoryView) then entirely creating a custom cell.
    Anyway thank you).
    It will be much beter if you could return the tableCell as native UitableViewCell to be able to use it with native object

    Found a solution for the Accesory Views with Native Objects ))

    Dim noTbl As NativeObject=MytableView
    Dim ip As NativeObject
    Dim cell As NativeObject=noTbl.RunMethod("cellForRowAtIndexPath:",Array(ip))
    Dim V As View

    Is it possible to have an image instead of text in the swipe button?

    No. Only text is supported.

    i have a question please

    when i intialize the tableview and create the items and then add the table to a panel everything is fine but then when i want to clear all items and load again new items to the tableview i get blank items. i solved it by intializing again the tableview but i think that its not the right way.

    what could be a reason for that behavior? thanx
