  4. Where has this talk come from? • Intranet ANZ website built with ASP.NET MVC 3 • 45,000+ users’ globally • Multiple web servers • Not all about lessons learnt, but tips too (c) 2011 Microsoft. All rights reserved.

  5. What will you learn today? • Handling exceptions • Ajax exceptions • ActionFilterAttribute order • Multiple form submissions • Routing constraints • ControllerActionInvoker • Security (c) 2011 Microsoft. All rights reserved.

  6. Handling Errors Error handling is absolutely required. In MVC you do things a little differently… • You still use customErrors in web.config • Alternatively you can handle exceptions at the action and controller level through ActionFilters • Or use global ActionFilters (c) 2011 Microsoft. All rights reserved.

  7. Handling Ajax Errors No more UpdatePanel as you may be used to in Web Forms! • Errors thrown on Ajax calls need to be handled with care, otherwise you’ll never hear them! (c) 2011 Microsoft. All rights reserved.

  8. Implementing Security MVC works slightly different Web Forms • You can still use the built in .NET Role and Membership providers. • Secure actions and controllers • Custom ActionFilters (c) 2011 Microsoft. All rights reserved.

  9. ActionFilter ordering ActionFilters are great, but it’s important to understand how they run. • They have a undetermined order starting at -1 • Security filters always run first! (c) 2011 Microsoft. All rights reserved.

  10. Handling multiple form posts Strictly ASP.NET MVC. • One form can have multiple submit buttons, so what’s the cleanest way to handle this scenario? • ActionMethodSelectorAttribute is your friend (c) 2011 Microsoft. All rights reserved.

  11. Routing constraints Routes are one of MVC’s biggest features • Understanding how to use them can turn your URL’s into a work of art • This tip show you how to change routes depending on the HTTP verb (c) 2011 Microsoft. All rights reserved.

  12. So what have you learned? • Error handling as well as handling Ajax errors • Implement security • ActionFilterAttribute ordering • ControllerActionInvoker to centralize handling requests • Routing constraints (c) 2011 Microsoft. All rights reserved.
