Diagram: Add an event notifying that ConnectionPoint is added or removed.
Currently there is no straightforward way to notify that a point is added/removed from the ConnectionPoints collection of the RadDiagramConnection.

Currently there are two possible workarounds for this issue:
1) You could handle the CommaneExecuted event and check if the command's name is Modify Connection Points:
private void OnDiagramCommandExecuted(object sender, CommandRoutedEventArgs e)
if (e.Command.Name == CommandNames.ModifyConnectionConnectionPoints)
var connection = this.diagram.SelectedItems.OfType<IConnection>().FirstOrDefault();
if (connection != null)
2) Use custom ConnectionManipulationTool (inherit ours), override its MouseDown method and check if in this case you'll add a new Point
