Edited Issue: PDF File upload in IE8 browser using Ajax fileUpload control [27693]

hi,
I have ajax fileupload control in my page to upload image files and pdf files. When uploading image files the functionality is good(Uploading file completely and refreshing the gridview control). When trying to upload the PDF file the ajax element showing continously "Uploading" with progress 0% and when refreshing the page after some time(not instantly) the uploaded file is shown in the grid.(The file is stored in the database).
