Navigation Properties

[Nick]

I am new to using the DataServiceDataSource Telerik control.  I have a RadGridView with data from a "Banks" table. [this part is working]  That Banks table has a navigation property(foreign key relationship) with a "Contacts" table.

How can I pass the BankID parameter and display all Contacts with that BankID to a grid?

Thanks,
Jorge

Hello Jorge,

Here you can see an online example of  a master-details implementation. This example follows the MVVM pattern and that is why we are using the collection called QueryableDataServiceCollectionView<T>. This is the same collection that the RDSDS control is internally using and is designed to be used in MVVM scenarios. The example could easily be re-worked to use two RDSDS controls instead of the two collections.

Let me know if you need further assistance.

All the best,

Hi Jorge,

I have attached a sample project with two controls for your convenience. Please explore it to see how to achieve master-details. The key to this is filtering, i.e. FilterDescriptors.

I hope this helps.
