Hello Parth,

The RadDiagram control does not support adding elements to its Items collection when its GraphSource property is set.

In this case, since the MVVM approach is followed, to add container shapes, new ContainerNodeViewModelBase<object> instances (or classes deriving from it) should be added to your graph source.

More information on this view model can be found at the following link:

WPF Diagram - ContainerNodeViewModelBase - Telerik UI for WPF

An example that contains such a setup is the MVVM one from our SDK Samples Browser. Additionally, its implementation can be checked in our GitHub repository:

xaml-sdk/Diagram/MVVM at master · telerik/xaml-sdk · GitHub

I hope the provided information will be of help to you.

Regards,
