Client-side API

RadUpload provides different client-side methods to manipulate the files selected for upload in the input file fields - clear the input fields, get the selected files names for further manipulation, etc. Two of them are:
- clearFileInputAt(index) - clears the value of a file input at the specified index in the RadUpload instance
- getFileInputs() - gets an array, containing all file inputs in the RadUpload instance. Cleint-side you can iterate through the selected files for upload whose number is getFileInputs().length
RadProgressManager exposes the OnClientSubmitting event which is triggered just before the form is submitted and is suitable for handling manipulation of the files selected for upload just before they are uploaded.
