Costume File upload

[cheacheap]

Hi community,

I am trying to implement pFileUpload to my angular 2 web app. I have a WB API to save files to the database in the backend.

Q1) I need to disbale the upload and cancel button after saving into DB and when I select one more file they sould be enabled.
Q2) I am unable to see the progree bar?
Q3) How can I hide the selectd files after saving into DB?

Thanks
