Contextmenu enabled anywhere in the datagrid on right mouse button

Question

Hello, I have the following problem: I have several records in datagrid and I want the moment I select a record and right click on it, a menu with options for the selected line appears. The only options in this menu are delete, details and print. I tried a solution that passed me another question that I did, but it did not work, because it enabled the menu anywhere in the datagrid that I clicked with the right mouse button
