Server Error in '/PLEWService' Application.

System.Data.DataRow cannot be serialized because it does not have a parameterless constructor.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: System.Data.DataRow cannot be serialized because it does not have a parameterless constructor.

Source Error:

Microsoft says: XML serialization can only be applied to classes that contain a public default (parameterless) constructor.

So this DataRow needs to be serialized. I think. :(
