ASP.NET MVC exception handling

Question

Is it OK to catch my exceptions in the controller's actions? Is there any better way of doing it? I'm actually catching my exceptions in the controller and using TempData to show a message to the user, but I have a weird feeling about this approach. I've been browsing around but I haven't found anything that suits me.

Answer 1

You can use the HandleError attribute on the controller class to catch any unhandled exceptions and it will automatically return the Error.aspx view in the Shared folder. There are overloads for this attribute so you can only have it used for certain exception types, etc.
