Hi Rocky et al,

I am using CSLA with database being Oracle. I am using Codesmith to generate CSLA classes (templates I converted to read Oracle).

My question is when there is No Data Found in a fetch it throws a DataPortalException, which is very generic in nature for the application. Is there a easy way (DataPortalResult etc), to figure from the DataPortalException thrown that is a No Data Found issue.

Many thanks, this is a great framework.

Yes, look at the BusinessException property of the DataPortalException to get the actual exception that triggered the problem.

I assume you as the developer are the one throwing the exception.

So you can make your own life easier if you decide up front if you just want to throw a New ApplicationException("No data found".)

Or else create a new Exception named NoDataFoundException and throw one of those.

Then in your UI you can catch the DataPortalException and get the inner exception and see what type it is - or if it has the string you expect - "No data found".
