Good morning,
I'm learning to program web now (I studied C # last year in college and this year is web, so I wanted to get ahead), I'm programming in ASP.NET, I made all my "form" in bootstrap, visually stayed as I wanted, all right, I created the event that clicked the button to program it, but everything I do it sends the form and erases the data, any of the buttons that click, even without programming anything for them, talking to a colleague of mine he said that This is because of js, which by default sends the form, if you have more than one button they will all send, and I need to replace this default! I just do not understand much of js, is that what he said? And how would I do it? Here is the video that shows what happens.
