How can I add a border to an individual DataGridView column?

Question

I need to somehow show the user that a specific column in a DataGridView is editable.

I want to add a Fixed3D border to only that column, but could not find a way.

How can I change the border style for a specific column?

Or, if that is not possible, are there any other ways to indicate that a cell can be edited?

Answer 1

You can simply draw a rectangle on that column, and you can move it or change its style programatically.
