Debug C# 2008 autogenerated code

Question

I am trying to debug an error on a C#.net 2008 desktop application. For some autogenerated code that was created when working with an .xsd, an error is occuring on a fill statement to a dataset. I know the error occurs here since I am stepping through the code and the debugger ends up on a catch statement that uses the autogenerated code.
Thus I am trying to determine how to find out what the error is. Can I put a try catch block in the auto generated code. What would you suggest I try?
