Hi,

 

Currently we have no good ideas to let client show the server side progress directly.

 

Now you can do this thing :

 

1 , on the server FileValidating event, start a new thread to copy the filedata to database, and return the request directly.

2 , on the client side, you can use the OnTaskComplete event, and start a new function to check the server side status.

 

We will consider a buildin API for that cool feature.

 

Regards,
Terry
