Hi Sanjeev If you are handling error usi ng MVC assemblies then you should maintain someUI to display error and user interactions. I would suggest to go for ELMAH assembly which you can get from Nuget. This help you to display error and if required store all logging or error in database connection string youspecify its very simple to implement in application. Refer the page for clear step by step approach. https://code.google.com/p/elmah/wiki/MVC Mark as answer if it was helpful.

Hi Possible ways are: Method 1:- Simple way Method 2:- Override “OnException” method Method 3:- Using “HandleError” Attribute Method 4:- Inheriting from “HandleErrorAttribute” Method 5:- Handling HTTP errors Method 6:- Global Error handling in MVC The best is combination of “Method 4” and “Method 6”. Create error handling classeswhich inherit from “HandleErrorAttribute” class and decorate them respectively on controllers and action methods. So this takes care of errors happening on controllers and actions. As a safety enable Global error handling as a fallback for any unexpected and unhandled errors byusing “Application_Error” event as described in “Method 6”. Let me know.
