MVC Grid and Many-To-Many Relationship

[Silviya]

Hello,

 I have Many-To-Many Relationship problem in my Grid.Searched the examples but could not find a way to do the column binding (unless using separate ViewModel). What I tried to do is:

columns.Bound(o => o.PERSON.EDUCATIONs.Select(m => m.E_DEGREE)).Title("Degree").Width("12.5%");

 That, of course, gives the following error:

Bound columns require a field or property access expression.

 

Is it possible to achieve the above?

 

Thanks

Hello Silviya,

I would suggest checking the following threads:

• Working with ManyToMany relations
• Grid with many-to-many relationship

Hy Silviya,

I'm working with Kendo and I've got the same problem with the Relationship in Grid.

I'd like to know if you have solved the problem and how.

Pleas ask me.

Hi,

can you publish a small sample project.

Is there an actual example done by Telerik? This is frustrating. All examples are partly there.

Hi Matt,

The Grid is designed to be used with flat data and we only provide a built-in functionality for ForeignKey column with one-to-many relationship. As suggested in the linked forum threads in the previous posts, for many-to-many relationship, Hierarchical Grid or custom editor could be used:
