Create a Persons Database using VS2013 and MySQL - Part 4 Populating a Combobox Tagging

Thanks for watching! I am a beginner in Windows Forms Applications Programming and currently practicing.
This is a video series in creating a Persons Database Application using Visual Studio 2013 and MySQL Server 5.2.
Previously, I have shown you how to populate data to textboxes when the user double clicks one of the rows in the datagridview list of persons.
In this video I show you how to systematically store data to combobox and retrieve data from database using LEFT JOIN and implementing RDBMS in persons profile status tagging.
