Improving existing method to async so we get indicator % progress when updating data to mysql server.

We have a simple form project in devexpress (.net framework 4.8, Winforms Project in C#). The user selects an excel file and the contents loaded to a gridview. Then with a press of a button all lines of the gridview are getting inside a mysql table on a remote server. I want to improve the uploading method to be async so i can have an overview of whats uploaded or whats left and how much % we are in.
