I am sure this is terribly simple, which is probably why its so frustrating that I cant solve it.
What I have is a class library that provides my data, so instead of binding to a database, I can select .Net Data Provider (.dll) and bind to that class.
So I have basic properties like Firstname, Lastname exposed of the travellers object. Cool. I can drop these on the Crystal Report (using CR10 for VS2005).
Now some magic happens on the inside that populates these so I dont need to care about the actual database connection (for instance I have hard coded values in a proxy object at the moment for proof of concept).
However, when I run this ASP.NET application I get a page telling me to log in!
The message is;
"The report you requested requires further information."
And then there is a logon box for the database name, username and password and checkbox for integrated security.
I have tried setting the report to use different ConnectionInfoType (ie; MetaData) but am all out of ideas.
Any clues out there really appreciated.
Cheers,
Steve

Found the answer!
My custom class needed to implement IEnumerable interface!
So quite simply I just made a generic list of my class.
For instance;
List<Traveler> _travelerList = new List<Traveler>();
_travelerList.Add(...
Then report.SetDataSource(_travelerList)
So the database connection error kind of threw me off the scent that the underlying type was wrong.

Thanks for the update. I'm about a month away for digging into Crystal Reports .NET 2005 to update my 2003 book. It's good to know that it's as easy as they advertise it to be.

Brian,
Tell me about your update to CR 2005. Will it be a new book or an update to your existing 2003 book. I have only used the versions of Crystal Reports that come with Visual Studio 2003 and 2005. I would be using another reporting source if it weren't for your book. I am anxious to see your "update" to VS 2005.
Thanks,
Bill V. ------------- Thanks, Bill V |
