Hello,
I am using Kendo 2013.1.514.340 with asp.net mvc.
I am sending the Json to the grid that is generated from the following data structure:
I have two entities, Parent and Child. A Parent can have n Children. In this case a single Parent has two Children.
I use NewtonSoft to serialize the Json with the following settings:
When I have the case of a single parent with a single child all works fine.
The following Json is generated for a single parent that has two children:
This leads to the following error:
I would really appreciate any about this issue!
Best regards

Hi Klaus,

Please note that currently the Grid supports only flat models out-of-the-box and I would recommend to flatter your model using View Model objects to avoid the serializing the properties which create the circular reference (refer to each other). I would suggest to check the "How do I avoid circular reference exceptions" FAQ section for further information.
