Temp file lost on postback

[David Blok]

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,
