The problem is that you have null events. As soon as the checkbox is created, it immediately raises the Unchecked event, which calls your btnToggleResizeMap_Unchecked handler, which tries to call your Expanded event. Since Expanded is null, an exception is thrown, and it never finishes running the XAML.
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.
