How to display checkbox on view (check or not) depending on their values in database (c# .net)?

I'm making an web app for my intership and here is my question. I'v got a form that users have to complete (only checkboxes to check or not) I already do the code to store the data in my database (as true/false) when they submit. But I also want to to display the checkboxe check or not when they return on that page depending on how they have been stored in database. And I don't find/know how to do it.

Here is the code i'v make for save them in databse if it could help ^^ Thx !
