Hello,

 
This can not be done on the client-side but you can use the OnFileUploaded event and if the e.File.ContentLength is zero to set the "IsValid" property to false

Hope this will be helpful.

How can I check it in client side instead of server side?

Hello,

 
Unfortunately this can not be checked on the client side.
