In C# .Net in Winforms, I found two events in almost all components, Resize() and SizeChanged(). Is there any difference between them? If both events are the same then why
The Resize event occurs when the control is resized, while the SizeChanged event occurs when the Size property changes.
You could use either, as a resize will cause the Size property to change. However, you should rather use the Layout event, as recommended both in the documentation for the Resize and SizeChanged events.
