the grid view will present the data as it is with the same columns names as the db table

the question is where did it get the names?

Answer 1

Are you using an entity model? If so when you create your model it generates classes for each table including properties which match all of the table columns from the database. When you set the DataSource to a list of these objects it will automatically assign the property name to the grid view as well.

You can use the HeaderText property of the DataGridView to specify custom text for the column headers if the properties aren’t to your liking:
