    Please try with the below code snippet.

    <script type="text/javascript">
                function onRequestStart(sender, args) {
                    if (args.get_eventTarget().indexOf("Download") >= 0) {
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
              <ClientEvents OnRequestStart="onRequestStart" />
    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
            if (e.Item is GridDataItem)
                GridDataItem item = e.Item as GridDataItem;
                (item["ClDown"].Controls[0]).ID = "Download";
