    I am implementing RadAsyncUpload, and need to give keyboard-only users the ability to browse for files to upload. 
    Following the Keyboard Support section of the demo site, I have set DisablePlugins=True, and added the recommended javascript to enable the tab and accesskey support. 

    I am running into the following issues:
    * Tabbing to the control and Select button works, but the Enter key does not activate selection of a file.  
    * The accesskey does not activate the Select button at all. 

    Any demos/help would be greatly appreciated! 

    Here's the code I'm using:

    <table id="Table11" cellspacing="1" cellpadding="1" runat="server">
               <tr >
                <td valign="bottom">
                         EnableTheming="true"        TabIndex="1"
    <script language="javascript" type="text/javascript">
      var $ = $telerik.$;
      var $cancelButton;
      // keyboardSupport() method activates focusing with TAB key
      function keyboardSupport(sender, args) {
        var $fileInput = $(".ruFileInput", args.get_row());
        $fileInput.attr("tabindex", "1")
        var $selectButton = $(".ruButton.ruBrowse", args.get_row());
        $fileInput.focus(function (e) {
          $selectButton.css("border", "1px dotted");
        $fileInput.blur(function (e) {
          $selectButton.css("border", "0px");
        $fileInput.keydown(function (event) {
          if (event.keyCode == '13') {
        if ($telerik.isIE) {
          $fileInput.keydown(function (e) {
            if (e.keyCode == && e.shiftKey == false) {
            if (e.keyCode == && e.shiftKey == true) {
              if ($cancelButton != undefined)
      function onClientFileUploading(sender, args) {
        $(".ruFileInput", args.get_row()).attr("tabindex", "-1");
        $cancelButton = $(".ruCancel", args.get_row());
        $cancelButton.attr("tabindex", "1");
      $(document).keydown(function (e) {
        var accesskey = $find("<%=RadAsyncUpload1.ClientID%>")._accessKey;
        if ($telerik.isFirefox) {
          if (e.altKey == true && e.shiftKey == true && e.which == accesskey.charCodeAt()) {
        if ($telerik.isChrome || $telerik.isSafari || $telerik.isIE) {
          if (e.altKey == true && e.which == accesskey.charCodeAt()) {
      function focusOnFirstInput() {
        var firstInput = $("input[type='file']", $get("<%=RadAsyncUpload1.ClientID%>"))[0];
        if (firstInput != undefined) {

    Hello Shoshanah,

    I've modified the page to make it work in IE9 as well. You can find it attached to this reply.
