  Hi Med,
  
  You can upload a file and save it into the folder using the following code snippet.
  
  ASPX:
  

  <telerik:RadUpload ID="RadUpload1" runat="server"></telerik:RadUpload>

  <asp:Button ID="Button1" runat="server" onclick="Button1_Click" />

  
  C#:
  

  protected void Button1_Click(object sender, EventArgs e)

      {

          if (RadUpload1.UploadedFiles.Count > 0)

          {

              foreach (UploadedFile file in RadUpload1.UploadedFiles)

              {

                  String targetFolder = Server.MapPath("~/Folder");

                  file.SaveAs(Path.Combine(targetFolder, "file.txt"));

              }

          }

      }

  
  Thanks,
  Princy.

  Hi Med,
  
  RadUpload cannot upload files using AJAX calls. This is a limitation of the XmlHttpRequest component, used in all AJAX frameworks for asynchronous calls to the application. In order to upload a file your application must perform a full page postback.
  
  The solution is to attach the following function to the OnRequestStart client side event of your RadAjaxManager:
  
  JS:
  

  <script type="text/javascript">

      // on upload button click temporarily disables ajax to perform

      // upload actions

      function OnRequestStart(sender, args) {

          if (args.get_eventTarget() == "<%= Button1.UniqueID %>") {

              args.set_enableAjax(false);

          }

      }

  </script>

  
  Please take a look into this for more information.
  
  Thanks,
  Princy.
