Difference between OnLoad method and Load event?

Question

What is the difference between OnLoad method and Load event? I am developing WinForm controls. Should I register to Load event or override

Answer 1

I'd go for overriding OnLoad, so you spare the CPU cycles to invoke the event handler.

The general pattern is to override a method, if you inherit from a control; otherwise, subscribe to the event.

But remember to call the base class' OnLoad method, because that's where the Load event invoked.
