How to get the value from the first cell of the selected row?

Question

C++ / C#

I'm making an application in visual studio WPF, connected the database via ADO. I am displaying data in the datagrid, but now I have encountered such a problem that I need to double-click on any cell of any row and automatically the program should determine on which row the cell that I poked is located and take the value from the first field from this row and display. (the first field is a counter, I need to find out the number of this line, on the cell of which the person has poked, in order to do other actions in the future) How can this be solved? what ways besides MVVM

maybe someone will come in handy. Working code

var printertable = NormApparatYchetEntities2.GetContext().PrinterTable.ToList();

            var currentItem = (PrinterTable)((FrameworkElement)sender).DataContext;
            MessageBox.Show(currentItem.IdPrinter.ToString());
