Hello Patrick,

To bind CustomObject using ISDataSource, you have to Configure Data Source, select Schema Type and Schema Name. Next, you need to add new table to  the ISDataSource's table list before you choose a business object to CustomObjects.DataLayer. Last, you have to set Select, Update, Insert and Delete method. And then you can retreive the structure to the WebGrid as well as you expected.

Could you please let me know wheter this step can be applied or not?
Attached is a simple sample BindToCustomObject using ISDataSource on clientBinding.

Hope this helps.
