title: C# - Refresh dropdown after a child form closes
body: <p>I have a c# application with multiple "worker" forms. These forms have numerous comboboxes that are populated from the database on form load, with 'add' buttons beside them. When a user clicks the add button the administrative form is opened allowing the user to add a corresponding value to the database.</p>
  
  <p>For instance, the combobox may be a list of street types. "Drive" is not in the street types table in the database, so the user wants to add it. They click the add button and the admin form is loaded so they can add the "Drive" value to the street types. When the admin form closes, I want to repopulate the combobox upon return to the worker form.</p>
  
  <p>Any insight as to the best way to accomplish this?</p>
