Hi Gab,

Please find the answer of your question below. Please note however that the official support language is English - that why I would ask you to provide the related information in this language for future support requests.

It seems that the collection provided to the ForeignKeyColumn is null - could you please confirm that the data is available n the "CatPlataforma" field of the ViewData? Also if possible provide runable example where the issue is reproduced in order to investigate further current behavior.

Vladimir Iliev. 

You should be aware that in Mexico the official language is Spanish, if you send the error is because my Spanish was Spanish Explorer. 

I understand I do not understand your answer. 

You will have an example with a database in SQL Server 2008.

Hi,

I will leave the thread open and wait for the sample project.

The problem with columns.ForeignKey I resolved already, now the problem is that the query did not work for filling the Grid.
