Starting from this article, we will illustrate how to implement component control programming. In the previous article, it is mentioned that the combination of component programming can achieve the effect of flexible adding function. So how is the combination? It is generally through events that the control's related events are handled in the Assembly, and the required functionality is encapsulated in the e
