HI, I have a scenario where I would like to validate all files before the upload process begins.  I'm currently handling the RadUploadItem.ValidateEvent to perform the validation.  A part of my validation process is to check a combobox value for a null selection.  If its null then I set the Cancel flag to true and the ErrorMessage of the UploadValidateEventArgs.  Any assistance would be much appreciated.
Thanks!
John
