Good morning, I have a problem with a multiple file upload.
1. Is it true that with multiple file selection there is no way to limit a user to say 10 files.
2. Which event should fire when a file is over the MaxFileSize.
3. Is there a way to limit an overall upload size? Ie can you set a max of 2Mbs so a user can only upload 4 x 500Kb files?
Thanks in advance,
Kevin

Hi Kevin,
With respect to your first question, yes, currently there is no way to prevent the user from selecting, say, ten files. The reasons are that neither Silverlight nor Flash provide API for the OpenFileDialog that would allow us to do such thing.
Regarding your second question, the correct event is FileValidationFailed. I suggest that you visit the following demo for a reference.
With respect to the last question, currently there is no way to do that with RadAsyncUpload. We will research the possibilities for adding such functionality for future releases.

Is there any workaround I could use with multiple file selection?
I dont want users trying to upload 100+ files at a time.
So I should be able to remove the file from the list of files to upload if the file size is greater than the MaxFileSize?

Hello Kevin,
This is a valid suggestion. We decided to expose a client OnFilesSelected event with the possibilities to cancel the event or to limit the number of selected files to upload. We will try to push it out as soon as possible, however I can't give you a specific time frame for it.
Additionally, we are currently preparing a knowledge base article that shows how to implement combined size validation on the temporary folder. We will release the KB article together with the upcoming Service Pack 2 release.

Was this KB article ever released? I've been unable to find it.
Thanks! Sara

Hello Sara,

The KB was not created because the client OnFilesSelected event was implemented in RadAsyncUpload and one can achieve this validation with it.

Hello,
Is there a way to set the overall max file size upload?
or is there any validation techniques that will work?
thanks in advanced.
