    We want to cancel uploading and remove last line if the selected file name was already uploaded.
    But we have many problems with RadAsyncUpload and IE8.

    This code didn't work with IE8:

     function onFileUploading(sender, args) {
        var fileName = args.get_fileName();

        if (uploadingFileNameIsValid(fileName)) {
            // code here...
        } else {
            alert('This file has been already uploaded. Please, remove the file uploaded or rename the file you want to upload.');
            // delete the display file name under upload control        
            var currentLiUpdatedFile = document.getElementById(sender.get_id() + 'row' + (sender._currentIndex - 1));


    The element currentLiUpdatedFile is null with IE8 unlike Firefox.

    We believe that this is a problem with silverlight plugin.
    So we try to use DisablePlugins="True" but in this case all uploads didn't work with this message :
    Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManagerUploadData_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3ac9cbdec3-c810-4e87-846c-fb25a7c08002%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2013.1.220.45%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a3e3b0da6-8c39-4d10-9111-25eaee1f7355%3a16e4e7cd%3aed16cbdc%3af7645509%3a24ee1bba%3af46195d3%3a2003d0b8%3a1e771326%3aaa288e2d%3a7165f74%3a52af31a4, Ligne 7409 Caractère 1

    However telerik resources are defined in web.config:

        <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID">
            <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" />
              <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource" validate="false" />
        <validation validateIntegratedModeConfiguration="false" />
            <add name="Telerik" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource" />


    Telerik.Web.UI Version : 2013.1.220.45
    ASP.NET version : 4.0
    Framework .NET : 4.5
    OS : Windows 7 x64
    IE 8 : 8.0.7601.17514

    Hi Jean-Michel,

    To remove duplicated files, first get the duplicated row and simulate a remove click:

    function OnClientFileUploading(sender, args) {
        var fileName = args.get_fileName();
        var uploadedFiles = sender.getUploadedFiles();
        for (var i = 0; i < uploadedFiles.length; i++) {
            if (uploadedFiles[i] == fileName) {
                var row = args.get_row();
                setTimeout(function() {
                        $(row).find('.ruButton, .ruCancel').click();
                    }, 100);

    Pay attention that this code use jQuery and you must reference it:
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
