Try doing a cast to IEnumerable before you return the result.  I know this should not be necessary, but I remember once doing it anyway, and it fixed my problem.]]> Wed, 31 Dec 2008 14:13:56 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1039&PID=3761#3761 DevForceDataSource : I did it exactly like the example.... http://www.ideablade.com/forum/forum_posts.asp?TID=1039&PID=3759#3759 Author: orcities

I did it exactly like the example. The example works and mine does not. The example has it return 1 record and it is successful. ]]> Wed, 31 Dec 2008 09:22:51 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1039&PID=3759#3759 DevForceDataSource : DevForceDataSource ia working... http://www.ideablade.com/forum/forum_posts.asp?TID=1039&PID=3757#3757 Author: davidklitzke

DevForceDataSource ia working as designed,  It expects a list of Entities, not a single Entity.  Therefore, you must return  a list containing a single Entity.  A single Orgnization is not the same as an EntityList<Organization> even when the EntityList contains a single  Organizatiion.]]> Wed, 31 Dec 2008 08:35:37 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1039&PID=3757#3757 DevForceDataSource : I am having an issue with the... http://www.ideablade.com/forum/forum_posts.asp?TID=1039&PID=3755#3755 Author: orcities

I am having an issue with the DevForceDataSource object when running the ExecuteSelect method.
 
I am mimicking the example:
-Create a dropdownlist for entities <Organization>
-Create DFDS to run GetAllEntities for <Organization>
 
Outcome: Runs successfully
 
-Create DetailsView
-Create DFDS to GetSelectedEntity using ControlParameter from the SelectedValue from the dropdownlist
 
Outcome: fails: Cannot cast Organization to IEnumerable
 
This does not make sense to me. ExecuteSelect for GetAllEntities is made of of a list of Organizations and passes. But, getting one Organization fails. List<Organization> is based off of Organization which is based from Entity which is based from DataRow. DataRow should be IEnumerable correct?
 
Please help. Been trying to track this down for a few days.
