    Hi Mazdak,

    The RadUpload is designed to work with a generic http handler on the server side. The events exposed by the RadUpload are for manipulating the RadUpload and the upload process before it has started. Once started, the upload will send http requests to the server and if you create a SampleUploadHandler that inherits the RadUploadHandler (like illustrated here), you will be able to upload files out-of-the-box.

    Only if you want to implement some custom behavior, you have to override some of the methods of the RadUploadHandler class and place your custom logic in them. You can fine more info here.

    Also, you can check out the examples added in our KnolwedgeBase, which illustrate the most common scenarios in which the RadUpload control is used.

    I hope this info will help you get started. However, if we can further assist you, please let us know.

    All the best,

    Sorry but I don't get it either.  Where's the code example we have to put in the .ashx for getting the files from the controls and saving the, on a multiplefile upload ?

    Can't find anything
    That's what I call incomplete too.

    In your demo, you have the .xaml, the .cs but you should add the .ashx code that goes with it

    I also tried to debug the context.Request and I don'T see any filename there that I've uploaded
    So how do you get the filename so you can use it to save the stream

    public void ProcessRequest(HttpContext context)
    {
        string filename = ?????;
      
        using (FileStream fs = File.Create("http://FooURL/Uploads/" + filename))
            SaveFile(context.Request.InputStream, fs);
    }
      
    private void SaveFile(Stream stream, FileStream fs)
    {
        byte[] buffer = new byte[4096];
        int bytesRead;
      
        while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) != 0)
        {
            fs.Write(buffer, 0, bytesRead);
        }
    }

    It's all right.  I did read the documentation and I saw that I had to add the RadUploadHandler as inheritence.
    and all the plumbing is done for me.
