crazy proj : No 3 - wpf and devexpress

1. wpf

In this area, I can only say that now I understand the minimal part of the whole picture.

And to demostrate this I tried to develop a simple calculator.

Three things I should know from this project:

a. understand the logic to event binding 

b. try catch to deal with exception

c. xaml's component's attribute Name can be treated as varibal in its partial class.

 

Next I should advance my understanding for wpf and make a small book management system.

Only with data model involved, I can make sure that I am able to use those fundamental tools in wpf.

 

2. devexpress

 Follow the documentation on its official website, I get this:

 

a. the northwind database is outdated, we should build a new one using the sql script.
