I'm going to read between the lines here. You have a "Event" class which represents some event. Events occur at some date and time and a location which we are calling a "Venue", the "Event" class has a string property which is the name of the venue.
If you can afford to bind the SelectedItem of the ComboBox differently (having a dedicated property seems superfluous anyway since you already have SelectedEvent) this should do it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
