[Solved] How to bind data of multiple level navigation property?

[wg]

Hi,

I have some tables in Entity Framework 4 models like this.

Entity 1: Name:   Project   Property: Id Name PeopleCollections(Navigation Property to Entity 2)
Entity 2: Name:   People   Property: Id Name DocumentCollections(Navigation Property to Entity 3)
Entity 3: Name:   Document   Property: Id Name

I have a master-detial RadGridView and a domainDataSource(ddsProject) to load Project entity.

In the master grid. I set ItemSource like this ItemsSource="{Binding Data, ElementName=ddsProject}". Working well.

In the deail grid. I just want to show Entity 3 (Document) list, not Entity 2(People). How can I set the ItemSource of detail grid? I tried ItemsSource="{Binding Path=PeopleCollections.DocumentCollections}" . It doesn't work.


Thanks in advance,
Bill

Hi,

 Can you verify your VS Output Window for binding expression errors? This should work properly if you have PeopleCollections property for your data item .

All the best,
