I am using the RadUpload control and have an issue with it, as follows:
When the submit button is clicked without selecting any file in the upload control, a postback occurs but the button logic isn't called. The form is then cleared with no error message displayed.
How can I detect this condition (no upload file specified) and handle it in a more graceful manner?
