[Solved] IList members values are getting lost

[Prasanna]

Hi Team,

We are new to ORM.  We have created the ORM objects for the database and when we query a table, it pulls all the fields along with the values from the other foreign tables related to this.  Although all the values are available in the current object, when we try to return the object to another program through a web service, some of the values were found to be missing. After digging through the code, we found that some of the members of the ORM class were generated of type IList, which are by nature not serializable, hence those members weren't passed through the web service. We tried changing the IList into List, but the program is not compiling.  Is there a way out of this?

Regards.

Hi Prasanna,

 First of all I would like to mention that using the OpenAccess objects that you already have for transport object over the service is not recommended. The solution that I would like to suggest is using DTO objects. This way you will have more control on what is happening and how object are passed trough the service.

Please have a look at this knowledge base article that shows how such object can be created. You should also know that in the Telerik OpenAccess SDK there is an N-Tier example using WPF and WCF Plain services with these templates that you can use as a reference.

I hope this proves to be helpful.

Kind regards,
Serge
