OnLoaded vs. Window_Loaded / event handler versus overriding

Question

What's better:

Private Sub Window_Closed(sender As Object, e As EventArgs) Handles Me.Closed
    'Do stuff
End Sub

---

Protected Overrides Sub OnClosed(ByVal e As System.EventArgs)
    MyBase.OnClosed(e)
    'Do stuff
End Sub

I personally think that the second is better, 1st because it doesn't add a handler, and also because the syntax is more simple. Especially in C#, where adding handlers is more robust, and there is no 'handles' keyword.

Answer 1

I would favour the event handler, because of maintainability:

• You can't forget to call the base class method MyBase.OnClosed().
• You can easily add multiple handlers.

It does not matter one bit, performance-wise. (I only add this because you tagged the question with performance-comparison... but really, this will only matter if you close forms millions of times a second.)
