HI all,
I created a .net object (ex: A
) which contain data have been collected from tables.
Next, i create a List<A>()
and pass to SetDataSource()
method of ReportDocument
object.
When i run then an Exception have been throwed :
"CrystalDecisions.CrystalReports.Engine.DataSourceException: The data source object is invalid"
I don't know the Exception above, Error message isn't clear. Can anybody explain for me? ex: the .net object must inherit from ISerializable.....
