How do we know in which Sub-Call did the error occured ?

I have defined a Method on a webform which further calls a long chain of other Inner methods and functions.

There are chances that error could occur in any of those methods in the chain.

But the error-trapping and error-logging code is written only on the webform. If an error occurs how can we know exactly in which of the inner function did the error occured ?

It will be the one at the bottom of the stack trace....or is it the top?

Just do an experiment. Write a simple app that has about 5 functions. Each one calls the next until you get to the fifth one. At that point, throw an error. Only handle it on the first function. Look at the error message to find the one that you know threw the error. It should be the first method, or the last method shown...just don't remember.


Better yet, you should catch the errors in every function. Add a message to them, then throw it again so the function higher can catch it.

try adding the "trace" directive to the top of your aspx page and set it = true It may help shed some light on you prob.
