Does elmah handle caught exceptions as well

Question

Does ELMAH logged exceptions even when they do not bubble up to the application? I\'d like to pop up a message when an exception occurs and still log the exception. Curren

Answer 1

A filter is the cleanest way to handle this problem. Check this solution here https://stackoverflow.com/a/5936867/965935

Answer 2

ELMAH has been updated to support a new feature called Signaling.

This allows you to handle exceptions how you want, while still logging them to ELMAH.

try
{
    int i = 5;
    int j = 0;
    i = i / j; //Throws exception
}
catch (Exception ex)
{
    MyPersonalHandlingCode(ex);
    ErrorSignal.FromCurrentContext().Raise(ex); //ELMAH Signaling
}

Re-throwing exceptions can be a bad practice as it makes it difficult to trace the flow of an application. Using Signaling is a much better approach if you intended to handle the error in some fashion and simply want to document it.
