Thank you for your continuous support.

 

Here is my situation:

 

I got a initially disabled Submit button which redirects to other page. What I want to do is to disable this button whenever there is file uploading. Is there any event fires up upon files selected for uploading? Any suggestion?

 

Hi,

 

Please check this

 

 

You can write some code in the client side javascript event handler.
