    <radscriptblock id="RadScriptBlock1" runat="server">
<script language="javascript" type="text/javascript">

    function OnClientBlurHandler(sender, eventArgs) {
        var textInTheCombo = sender.get_text();
        var item = sender.findItemByText(textInTheCombo);
        //if there is no item with that text
        if (!item) {
            sender.set_text("");
        }
    }

</script>
<script language="javascript" type="text/javascript">
    function AddNewFields(radUpload, args) {
        var FildNameLable = '<% = Resources.TMS.UI.TM_AddNewTask_lblAttachmentFileName%>';
        var curLiEl = args.get_row();
        var firstInput = curLiEl.getElementsByTagName("input")[0];
        var input = CreateInput("Title", "text");
        input.className = "copyOfRADTextCSS";
        input.id = input.name = radUpload.getID(input.name);
        var label = CreateLabel(FildNameLable, input.id);
        var fileInputSpan = curLiEl.getElementsByTagName("span")[0];
        var firstNode = curLiEl.childNodes[0];
        curLiEl.insertBefore(label, fileInputSpan.nextSibling);
        curLiEl.insertBefore(input, label.nextSibling);
    }

    function CreateLabel(text, associatedControlId) {
        var label = document.createElement("label");
        label.innerHTML = text;
        label.setAttribute("for", associatedControlId);
        label.style.fontSize = 12;

        return label;
    }
    function CreateInput(inputName, type) {
        var input = document.createElement("input");
        input.type = type;
        input.name = inputName;
        return input;
    }
