ASPX

<script runat="server">
 public partial class UploadControl_MultiFileUpload : BasePage
 {
     const string UploadDirectory = "~/UploadControl/UploadImages/";
     const int ThumbnailSize = 100;

     protected void Page_Load(object sender, EventArgs e) {
         if(IsPostBack)
             UploadControl.ShowProgressPanel = chbShowProgressPanel.Checked;
     }

     protected string SavePostedFiles(UploadedFile uploadedFile) {
         string ret = "";
         if(uploadedFile.IsValid) {
             FileInfo fileInfo = new FileInfo(uploadedFile.FileName);
             string resFileName = MapPath(UploadDirectory) + fileInfo.Name;
             uploadedFile.SaveAs(resFileName);

             string fileLabel = fileInfo.Name;
             string fileType = uploadedFile.PostedFile.ContentType.ToString();
             string fileLength = uploadedFile.PostedFile.ContentLength / 1024 + "K";
             ret = string.Format("{0} <i>({1})</i> {2}|{3}", 
                 fileLabel, fileType, fileLength, fileInfo.Name);
         }
         return ret;
     }
