    I have created a very simple page to reproduce this error

    This error is happening on ipad safari or chrome

    you can also reproduce it on chrome by emulating Apple Ipad.

    Once the page load, Select a radlistboxitem such as "2", now try to press the button. it won't postback.

    Any help would be appreciated

    <body>
        <form id="form1" runat="server">
        <asp:ScriptManager runat="server" ID="sm1"></asp:ScriptManager>
        <div>
        Available
        <telerik:RadListBox runat="server" ID="lbUnselected"  Height="250px" SelectionMode="Multiple" AllowTransfer="true" TransferToID="lbSelected" AllowReorder="true" EnableDragAndDrop="true" />
        <br /><br />
         
        Selected
        <telerik:RadListBox runat="server" ID="lbSelected"  Height="250px" SelectionMode="Multiple" AllowTransfer="true" TransferToID="lbUnselected" AllowReorder="true" EnableDragAndDrop="true" />
        <br /><br />
        <asp:Button runat="server" ID="btnDo" Text="Do" />
     
        </div>
        </form>
    </body>

    and code behind

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            lbUnselected.Items.Add(New RadListBoxItem("1", "1"))
            lbUnselected.Items.Add(New RadListBoxItem("2", "2"))
            lbUnselected.Items.Add(New RadListBoxItem("3", "3"))
     
            lbSelected.Items.Add(New RadListBoxItem("4", "4"))
            lbSelected.Items.Add(New RadListBoxItem("5", "5"))
            lbSelected.Items.Add(New RadListBoxItem("6", "6"))
        End If
    End Sub
     
    Protected Sub btnDo_click(sender As Object, e As EventArgs) Handles btnDo.Click
        Dim here As String = ""
    End Sub

    Hello Nico,

    I am afraid that I am not able to replicate the described issue locally. Could you first specify what exactly is the error, encountered at your end. Also, please specify the version of our controls that you are using.

    In addition, regarding the demonstrated implementation - I would suggest you to omit the association of the destination ListBox (Selected) with the source ListBox, because the association for transfer should be implemented only in the first ListBox.

    I'm not getting any javascript or server errors, I'm just not able to generate a postback by pressing the button. Its like its not possible to press the button once one of the radlistbox have been touched. (this is only happening on mobile devices, it works fine from a desktop browser)

     I have the version: 2012.912.40

     I removed the second association but still have the same problem.

    Hello Nico,

    We were able to reproduce the issue with the provided controls version. Fortunately it is not reproducible with the latest official version (2015.3.930) so we recommend updating the controls.
