I have done some checking here before writing this and a little experimentation to make sure the answer in not very simple. Reporting is a key component of my application, and Im sure of other developers too. I use Visual Studio and historicaly I have simply used Crystal report becuase I don't have the money to buy yet another component to assist Visual Studio. I like EntitySpaces fine and it works for all my data CRUD chores except this; populating a Crystal report object's datasource. Perhaps it would fill the datatable but how do I use the crytal report interface in design mode without the prefuctory DataSet. Any suggestion. Should I use the MS reporting component instead. I am familar with Crystal report and don't like to stray from what has served me well.

The real issue with using EntitySpaces native business objects as a datasource for Crystal Reports is that the last time I checked they STILL did not support nullable types. My recommendations would be to dump the objects out to DataSets/DataTables or create views to generate your reports from. While I understand using our native objects is ideal, the ball is really in Crystal's court to update their reporting engine to support nullable types.

An easy way to test this it to expose the protected "Table" property and bind to it for your Cyrstal Report.
