    Currently We are using silverlight for uploading files. But seriously considering to move into radUploader (since its supports
    multiple  uploading).

    I'l be glade to know what are the advantages of the Raduploader vs Silverlight uploading ( specially 
    considering files types supported)

    Best Regard

    Hi avi,

    May be the biggest advantage is that RadAsyncUpload can work even if the  user do not have Flash installed. We have implemented html/javascript based async upload control that handles such cases. Apart from this, the Flash and Silverlight upload are pretty much equal. Both support client-side size validation and can be used for multiple files selection. However, the Flash upload currently has one drawback. One can't apply extension filtering whereas in the Silverlight uploader this is possible. The good news are that we are well aware of this problem and we will get it resolved for the next service pack or at latest for the next Q. As for the files type supported, I am not quire sure what you mean. Could you please clarify?

    All the best,

    1. you mentioned that RadAsyncUpload can work without flash installed, but as i saw at your api description it can't support multiple upload if flash isn't installed (i also build a test application and confirmed that the multiple upload dont work)
    2. i noticed that u support extension filtering by "AllowedFileExtentions" property.

    Hello avi,

    RadUpload supports multiple uploads, but not asynchronously like RadAsyncUpload(with Flash enabled) or RadUpload for Silverlight does.

    The AllowedFileExtensions property is a setting that the RadUpload control uses when validating the file. So if you set it to only allow PDF files to be uploaded it will only upload those files. The confusion or question I'm assuming your asking is that this property will limit the file selection that the user can select from "File Select Dialog", which it doesn't, only Silverlight's Upload control can do that. The RadUpload and RadAsyncUpload are only able to validate the file once the user selects it and through javascript, if you code the validation check, will stop the upload if the file extension is not one of the approved types, otherwise it will upload it and add it to it's InvalidFiles collection.

    I hope that answers your questions.
