Hello,

<script type="text/javascript">

       function onRequestStart(sender, args) {

           if (args.get_eventTarget().indexOf("btnDownload") >= 0) {

               args.set_enableAjax(false);

           }

       }


   </script>

        //write below code inside content page


protected void Page_Load(object sender, EventArgs e)

    {

  

        //get master page's RadAjaxManager in Content page

        RadAjaxManager RadAjaxManager1 = (RadAjaxManager)this.Page.Master.FindControl("RadAjaxManager1"); // method 1

        RadAjaxManager RadAjaxManager2 = (RadAjaxManager)Master.FindControl("RadAjaxManager2"); //method 2

        RadAjaxManager RadAjaxManager3 = RadAjaxManager.GetCurrent(Page); //method 3

  

  

        // disable ajax at the time of download

        RadAjaxManager1.ClientEvents.OnRequestStart = "onRequestStart";

  

}
