RadAsyncUpload check file exist on client side

[Alaaeddin]

am using RadAsyncUpload to upload flles to the server and want to check if file name exist on client side then javascript popup to confirm overwrite or change file name by adding +1 to the filename.

I tried to use these script on server side and also didn't goes well for me .

Protected Sub RadAsyncUpload1_FileUploaded(ByVal sender As Object, ByVal e As FileUploadedEventArgs)
       Dim targetFolder As String = "~/Files"

       Dim targetFileName As String = Path.Combine(Server.MapPath(targetFolder), e.File.GetName())
       If Not File.Exists(targetFileName) Then
           e.File.SaveAs(targetFileName)
           txtpath.Text = targetFileName
           ' Implement logic
       Else


           lbresult.Text = "failed to upload"


       End If
   End Sub

and also this code :

 

Private Sub RadAsyncUpload1_FileUploaded(ByVal sender As Object, ByVal e As FileUploadedEventArgs)
            Dim fullPath As String = Server.MapPath(Path.Combine(RadAsyncUpload1.TargetFolder, e.File.GetName()))

            If File.Exists(fullPath) Then
                e.IsValid = False
                e.File.SaveAs(Server.MapPath(Path.Combine(RadAsyncUpload1.TargetFolder, e.File.GetNameWithoutExtension() & "1" & e.File.GetExtension())))

            txtpath.Text = "http://www.xxxxx.org/Files/" & e.File.FileName

        End If
        End Sub

Hi,

Try the following code to achieve your scenario.
C#:

protected void RadAsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
{
  foreach (UploadedFile NewFile in RadAsyncUpload1.UploadedFiles)
    {
        string strPath = Server.MapPath(RadAsyncUpload1.TargetFolder);

        FileInfo file = new FileInfo(strPath + "/" + NewFile.FileName);
        if (file != null)
        {
            e.File.SaveAs(strPath + "/" + NewFile.GetNameWithoutExtension() + "1"+ NewFile.GetExtension());
        }

    }
}

Thanks,
Shinu.

thankss alot. I resolved .

The control is invisible now , I can see it in the Design mode but when upload to server the page is blank with no control.
Also how to read the final filename after the change ? how to trigger upload action ?

Can you please write the full code ?

Hello Alaaeddin,

My suggestion in to ask the user for that confirmation before the file is being uploaded. E.g. "Do you want to overwrite existing files or save them under new names."  After a postback you will now users' decision and will handle the cases in FileUploaded server side event.
