    I am using RadListBox, I want to get all values of listbox.
    I am tying to use "get_items" method But it is showing foll. error.
    Uncaught TypeError: Object [object Object] has no method 'get_items' 
    ASPX code
    <script type="text/javascript" charset="utf-8">
            $(document).ready(function() {
     $('#<%=btnViewAssignedSlots.ClientID %>').click(function() {
                   var list = $('#<%= rdLstSource.ClientID %>');
                    var items = list.get_items();
                   var firstItem = items.getItem(0);

    <telerik:RadListBox runat="server" ID="rdLstSource" Height="200px" Width="230px"
                            AutoPostBackOnTransfer="false" AllowTransfer="true" TransferToID="rdLstDestination"
                            AllowTransferOnDoubleClick="true" EnableDragAndDrop="true" ButtonSettings-ShowTransferAll="true">
                                <telerik:RadListBoxItem Text="Sunday" Value="1" />
                                <telerik:RadListBoxItem Text="Monday" Value="2"/>

    Try the following javascript.
    <script type="text/javascript">
        function OnClientClick()
            var list = $find("<%=RadListBox1.ClientID %>");
            for (i = 0; i < list.get_items().get_count(); i++)
