How to use file dropper?

Hi Experts, Hope you are doing good! I want to configure file dropper to let user add document by clicking button. i am using DataGrid2 in which button is there after clicking that button i want to show a file dropper from where user will select file to upload. As soon as user uploads file the browse field should get emptied and file uploader should get hidden. Can you please advise how can I achieve this?   Thanks for all suggestions and ideas.

Based on what you are asking, you need a pop up window appear when you click on your magic button. The window contains the file dropper. Your save button should close the popup.

Unless I am missing the complexity of your task.
