I need to create the file on the fly in SilverLight then upload it.
How can I use the SL RadUpload with a FileStream or How can I programatically add the file from Isolated Storage.
i.e I create the file name OK but IsloatedStorageFile does not seem to give up it directory.
All I'm trying to do is create a file on the fly to add to the upload of several user selected files.
Is there an easier way to do this?
Thanks

It seems that the only way to add items/files is with the file dialoge (the items collection is read only). I don't know if this is by design, but I would also like to see this feature (FileStream or MemoryStream).

Hello Jorn,
Currently, Silverlight can access files only through OpenFileDialog or as out of browser application with elevated trust. Uploading a memory stream directly is currently not supported with the RadUpload.
Assuming that you have a collection of FileInfo objects, you can wrap them into RadUploadSelectedFiles and add them in the RadUpload.CurrentSession.SelectedFiles collection and ready them for upload.

I know that SL only can access (local) files through OpenFileDialog, but I think it would be a nice to handle all uploads in our application through a single interface. If RadUpload could access memory streams and upload them as if they were "real" files it would not break any security (or would it?). For example; if I have a RichTextEditor open and want to save documents on the server (not in the DB) it would be nice to route the stream to RadUpload.

Hello Jorn,
Your best option with using a memory | file stream for now is using the FileUploadStarting, described in this forum thread. There is also a sample project provided by Tina Stancheva. We are also considering utilizing WCF services with the RadUpload, which will allow uploading directly from a stream. You can vote for this request here.
