When we upload any document its takes the full length of File path is displaying in File Name text box field, instead of file name while selecting file to upload.
The full path will appear only when testing on a localhost, in
developing environment. When you website is hosted on real production
server, the fullpath won't be visible due to security reasons. This is
not limitation of RadUpload but is the way the browsers deal with the
<input type='file' /> tag.
