    I've set up a new project with Data Access and Dynamic Data, based on an existing database with several many-to-many relationships. The relationships are ​implemented as pure join tables and displayed correctly in the Data Access model. When displaying the data in the Dynamic Access application, the related entries are displayed correctly.


    However, when editing an item, the related entries are read-only. They are displayed, but there's no checkbox. Likewise, when inserting a new item, the field is just empty.


    .NET 4.5

    Visual Studio 2012

    Telerik DataAccess 2013.2.611.1


    Any ideas?

    Hello Chris,

    Unfortunately, due to some internal specifics, this scenario is not supported with the our dynamic data implementation. Nevertheless this feature is provided mostly for testing and internal purposes, mostly to allow you to view and validate your data and model.

    This is why, once you have your model and data up and running, we would recommend you to expose and manage your data through a service layer. If you would continue to use a Telerik Data Access version that still supports the Visual Studio integration, the Telerik Data Access Service wizard will be available to you. This tool allow you to generate the foundation of a service layer based on a Telerik Data Access model. It supports various service technologies and you should choose the one that best serves your implementation requirements. Please read more about it in this documentation article.

    Please excuse us for the inconvenience caused.

    Should you have any further questions do get back to us.

    Check out the latest announcement about Telerik Data Access vNext as a powerful framework able to solve core development problems.
