Hi.

I'd like to be able to disallow the user from selecting connections between the nodes.

I.e.: The user selects a group of nodes on the canvas by dragging the selection rectangle to include the desired nodes. By default, the connections in the rectangle are selected too: They are included in the SelectedItems (IEnumerable) at the time the SelectionChanged event is fired.
Is it in any way possible remove the links between the nodes from the selected items.

Okay, I have now discovered the SelectionService, which I can get a reference to using the ServiceLocator on the diagram.
If I iterate over the SelectedItems property of the selectionservice I can set the IsSelected property to false for the items that I don't want selected. So far so good.

Is that the recommended way to do what I want?

Hello Thomas,

We encourage our customers to use and extend the services exposed by the RadDiagram. This is why your approach is correct and recommended. 

Also, you can consider checking (or clearing) the SelectedConnections property.
