wish help you to fix your issue I'm creating a website and I want to display my data into a slideshow from database. The slideshow is made using bootstrap. , In your function make_slides, change the class item to carousel-item
I hope this helps you . If I remember correctly the datagridview must not be data bound in order to manipulate the rows. I believe that I solved this problem a couple months back but I can't get access to my projects right now.
