Hi,

I am using Infragistics Upload control in Asp.net MVC3 application, my question is how to handle if the uploaded file already exists on server? I see that for default setting the new uploaded file will overwrite the existing one on server.

And I learned from the following topic that we can add handler in Global.asax or controller. 

"How to add time stamp to the uploading file name using Webupload?"

I added some code  in Global.asax to change the file name if it exists, but how do I know the changed file name on client side? For example, if the file name is abc.txt, server code may changed it to abc20120529.txt, how does the client javascript know the new file name, since I need save it to database.
