Using a ComboBox to open a FileDialog

Question

Hello Forum, I have a question regarding the best way to use a ComboBox for opening a FileDialog. I am trying to use a ComboBox to display a list of recently open files. The top (1st) item in the list is always 'Open Other File'. My problem is that if there are no recently open files, (meaning that the only item in the list is the 'Open Other File'), the 'SelectionChanged' event will not work due to the selection not been changed. I am unsure what other event to fire that would make the dialog appear. Any help with this one will be gratefully received. Kind Regards, Harold Clements
