Allowing different file sizes for different document types

Reply Quote

Hi,

I'm currently working on an uploader that allows images (.jpg, .gif, .png) and documents (.pdf, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .txt, .rtf)

I'd like to be able to set validation so that the max size of images files is 3 MB and document files is 10MB.

Is this possible?

Thanks,

Andrew

Dear casso,

You can refer to the following snippet:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
    void InsertMsg(string msg)
    {
        ListBoxEvents.Items.Insert(0, msg);
        ListBoxEvents.SelectedIndex = 0;
    }
    void Uploader_FileUploaded(object sender, UploaderEventArgs args)
    {
        InsertMsg("File uploaded! " + args.FileName + ", " + args.FileSize + " bytes.");

        //Copys the uploaded file to a new location.
        //args.CopyTo("c:\\temp\\"+args.FileName);
        //You can also open the uploaded file's data stream.
        //System.IO.Stream data = args.OpenStream();
    }
</script>

                   alert(files[i].FileName);
                   if (files[i].FileName.indexOf(".pdf") != -1 && files[i].FileSize > 1024 * 1024 * 3) {
                       alert("the file size of pdf file should be less than 3M");
                       return false;
                   }
               }
           }
