10/May/2015	1.0	Realize the APP with binding.	Tang Hongyao
17/May/2015	V2.0	Give up binding, change another way.	Tang Hongyao

 

Problem Statement

 

　　At first, I don't know how to realize the saving and loading data that user write in. I watch the teaching video and ask my classmates, then I know I may need to use Json file to realize this.

　　It's not enough to know how to serialize and deserialize the Json file, I need to write the DataTemplate and use binding to bind the controls content to the class properties.

　　And then I find that if I change the properties, my controls' content won't change, and after the teacher's help, I know I need to realize the interface named INotifyPropertyChanged, than the binding will refresh, so the user can see the changed data.

　　When everything came to the last step, I tried 100 ways to solve the initialization problem of my Json file and binding but failed, I think there are some logical problem in it. And I did not have enough time so I changed the method to realize this APP. So, version 2.0 comes.
