Default Error Handling

I've managed to successfully incorporate the PhilPage_Error event (which displays a customized, detailed error message) into my pagebase class of my own site. Here is my question regarding this event:

Being this event is for trapping errors which are unaccounted for in try-catch blocks in a given site, would it be considered good practice to do away with try-catches altogether and just rely on this event handler to fire everytime there's an error? If not, what are the drawbacks?

A "one size fits all" approach usually doesn't!

If you handle exceptions locally you can include extra context infomation in the error log, and you might be able to take corrective action in some cases.

Having a single place to log all errors normally doesn't give you enough information to deterine exactly where the error occured, and what the circumstances were surrounding the error.

You might want to look at Microsoft's Exception Management Application Block to learn more about "best practices" concerning the handling of exceptions.
