    I use the Export feature in RadGrids on many pages to export Excel, MSWord and PDF documents.  It works on all but one page.  The culprit throws the PageRequestManagerParserErrorException when Visual Studio is in Debug mode.  Furthermore, if I try to export an Excel document, Fiddler shows that the response header’s Content-Type is “text/plain;  charset=utf-8” instead of “application/vnd.ms-excel;”, and the WebView and Raw view is gobble-de-gook.  Please help.

    Hello David,

    It seems that on the page that you are experiencing that problem, the grid is AJAX enabled, which is not supported scenario with the exporting functionality. However, you could have a look at the following help article, which explains in details how to export from AJAX enabled RadGrid:
    Hope that helps.

    Yes.  Thank you.  Actually, I found an unnecessary AjaxSetting in my RadAjaxManager.  I added it while degugging something else.  It was tied to the user control that contains the export button.  When the setting was removed, the exports began to work again.

    This is a bit of an old topic, but I'm having a similar issue where the RadGrid ExportToExcel() method is generating output that includes a header item "<meta http-equiv="Content-Type" content="text/html; charset=utf-8">" in addition to the the header also showing a content-Type of "application/vnd.ms-excel.  Our security scanning software is returning an error saying Multiple conten types are specified.  Is there a way to get rid of the <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> definition?
