I have an application where users upload PDFs and images. I would like to minimize the size of these files by compressing them or using a library to reduce the image quality.I feel that I could probably find a server-side library more easily than a silverlight one for compressing/quality lowering. So, is there a way in the RadUploadHanlder to get the file data, manipulate it, and then return it to the client? The client app would then later save the file to a database in the compressed format.

Thanks,

Dave

Hello Dave,

From the FileUploadStarting event, you can modify the file stream of the file before it is being uploaded. It is available through the event's args e.NewFileStream. You can use this in case a silverlight compressing library. If you are using a server sider compression library, you would not be able to return the compressed file stream back to the client. You can return parameters, but they will be just string parameters.

All the best,
