    I have following code snippet used for deleteing an selected item from ListBox. Following is the aspx code



    telerik:RadListBox ID="rlbTag" runat="server" AutoPostBack="false" OnClientItemDoubleClicked="DeleteTags()" Width="250" EnableEmbeddedSkins="true" Height="80px" AllowAutomaticUpdates="true">






    <table width="100%">






    <td align="left" ><asp:Label ID="lblTags" Text='<%# DataBinder.Eval(Container, "Text") %>' runat="server"></asp:Label></td>



    <td align="right"><asp:ImageButton ImageUrl="~/images/Delete.gif" ID="btnDelete" Text="Delete" OnClientClick="return removeItem(event)" runat="server"/></td>



    --<asp:CheckBox id="cbUsers" runat="server" OnClick="checkboxReportClick(event);" Text='<%# DataBinder.Eval(Container, "Text") %>' />--%>
















    Following is the implementation of removeItem method which will be triggered when user click on delete button in List Box item template









    var RdListBox=$find("<%= rlbTag.ClientID %>");




    var item = RdListBox.get_selectedItem();


    RdListBox._selectedIndex = 0;






    When  first time user clicks delete button to remove an item, selected item is gettiung null. Seconmd time it gets deleted from the list.
    Can anyone help me to acheive remove functionality on cleint side?
