Check File Size

Smart Client v8.3

I'm building an upload functionality on one of my forms. I wanted to check the file size before uploading the file to my servers. I have found some ways to do it using the traditional HTML input element, but I couldn't do it using the SmartClient formItem.

Does SmartClient offers a way to check file size? Or is there a way for me to get the HTML input element from the SmartClient object?

Thanks
