Lost error in a namespace

[dnagroove]

Hello to all and thank you for your attention...

I've built a solution with several projects, each project is a namespace, except for the main project which has all of the aspx files. The problem is that there is one namespace that generates an error ('Object reference not set to an instance of an object') but the line returned is the line that initiates the class within the ASPX file, instead of the line inside the namespace - where the error actually is.

Is there a certain declaration property of the namesapce/class? How can I find the actual line inside the namespace?

Thanks again.
