I have some question.

The Diagram.ExternalObjectsDropped event is raised when the user successfully drag-and-drops from one Diagram to another Diagram.
Every transaction causes all invalid layouts to be performed. But no event inherently requires a layout to happen. But what you describe is common.
i don’t understand
why TreeLayout.DoLayout method called?? after ExternalObjectesDropped ??
The LayoutManager decides whether a layout needs to be performed again automatically at the end of a transaction.
Adding or removing nodes or links will normally invalidate the layout. GoXam for WPF v3
