Uploading Large Files
Source Code & Description
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
RadUploadManager 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.
