Question

In ASP.NET, if I override a page lifecycle event, should I call its base method before or after doing my work? Does it even matter?

protected override void OnPreRender(EventArgs e) {     // My code goes here     base.OnPreRender(e);     // Or here }

Yes you should care. Let’s say for a moment that you need to insert a new base class in all of those pages. To me it’s easier to just go ahead and call the base methods than have to do a lot of refactoring later.

Then again, maybe you don’t need to do that.

EDIT
Based on the edit to the question here’s some more info:

Yes, you should care. Sometimes you want the base classes method to fire before yours (in case of constructors), and sometimes you want it to fire after yours (destructors).

It may mean the difference between whether a property or object is available or not at the time your code gets to it.
