Scrollviewer Scrollbar doesn't appear - .net-4.0

Question

I am not able to get the Scrollviewer to working in WPF. I guess I am doing something wrong but not able to figure out what. I also made sure that I am not using the ScrollViewer in side a StackPanel. Please note there are 2 of them and none seems to work.
I did try to fix the size of the ScrollViewer parent container to restrict size, which works, but that's not what I want to do. I want to make sure that on resizing the window, the increase of size happens in the containers appropriately.
Here is my code, I did change the strings and paths as this is a part of client application:

Sorry for the huge code, but that's what I have. Also, please leave a comment for downvotes.
