DependencyProperty

-What is the purpose?

 

To process the binding relationship, we often want to modify the data at the front end and back end at the same time. The foreground is the property of the control, and the background is the memory object. DependencyProperty is defined to ensure the consistency of the front and back-end modifications.

 

Demo
