Hi, i'm trying to upload some files and write them away.
But everytime i do a postback the files are gone, anyone have an idea what i'm doing wrong ?

Front end code
<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" MultipleFileSelection="Automatic">
</telerik:RadAsyncUpload>


Backend
Protected Sub btnsaveimages_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnsaveimages.Click
         If RadAsyncUpload1.UploadedFiles.Count > 0 Then
             For Each file As UploadedFile In RadAsyncUpload1.UploadedFiles
                 file.SaveAs("~/" + file.FileName)
              Next
         End If
     End Sub

Or on fileuploaded
Sub RadAsyncUpload1_FileUploaded(ByVal sender As Object, ByVal e As FileUploadedEventArgs) Handles RadAsyncUpload1.FileUploaded
 
        e.File.SaveAs(Server.MapPath("~/Upload/Images/ImgGallery/2/" + e.File.FileName), True)
 
    End Sub


I always get the following error: 
Could not find file '***********\App_Data\RadUploadTemp\1341910388330Lighthouse.jpg'.

Hello David,

Are you using both handlers at the same time? The SaveAs() function of the uploaded file removes it from the temporary folder, so if you try to save it a second time, this error is expected. 

To get the RadAsyncUpload working properly you have to use either one of the two handlers, but not both at the same time.
 
All the best,
