[Solved] circular reference was detected while serializing an object

[Niels Schneider]

I'm using EF4 as a datasource for the Grid. I'm using the POCO templates with the lazy loading functionaliteit enabled. When actions on the grid are defined:

 

columns.Command(commands =>

{

commands.Edit();

commands.Delete();

}).Width(180);

Then a exception will occur complaining about a circular reference. In my case a Customer has a reference to one of more invoices and an invoice has a ref back to customer.

Problem occurs with serializing the data with the standard javascriptSerializer from the .Net framework which cannot handle this.

Has anyone a solution for this problem.

Hi,

When I removed problem in serializing my entity Customer (EF), I am getting new one:

A circular reference was detected while serializing an object of type 'System.Data.Metadata.Edm.AssociationType'.

Any ideas?

Hi Atanas and P,

Thank you for the response. Described solutions work, but cannot be used in my situation. Shall look into this at a later time.

Niels.
