Hello,
I'm using your RadUpload control in my silverlight application. When the user has selected a file for upload, some logic is executed to determine the name and extension of the selected file and to set additional post fields. (I use the FilesSelected event for that).
But I would like to disable the upload button programmatically when something goes wrong while this logic is executed, so that the user can not upload the file. What is the best way to implement this functionality?
Thanks,
Sodi
