Question

I want to add a friendly error page to my application that would say a text like, “Oops some thing went wrong”. I want the error page to be displayed automatically for every page of my application in the even of an exception. How can I achieve this?

Answer 1

Simply enable custom errors in web.config:

<customErrors mode="On">

</customErrors>

and the ~/Views/Shared/Error.aspx view will be rendered on unhandled error (assuming your controller is decorated with the [HandleError] attribute).

Then you can have more fine grained control and different views for different exceptions:

[HandleError(
    View = "~/Views/Errors/Custom.aspx", 
    ExceptionType = typeof(SomeCustomException))]
