The DataGridView class is huge and complex.
It is a beast I'm still struggling with, but once you learn to comprehend it, I find it most rewarding!
Some try to circumvent it by using listboxes and the lot.
Why don't get your feet wet with this as basic as it could get code!
Start a WindowsFormApp, drop in a DataGridView and a Button control.
Fill in the code where needed.
Have fun!

This is one control I've been avoiding :)
