	Hello, Still in WPFDiagram evaluation ... I've tried the TreeLayout demo, and +/- buttons are mentioned in the bottom of the form, but I don't see them in the diagram ? - When you collapse a tree node, is the layout recomputed ? (meaning ocupying the freed space by collapse) - Is it possible to set the spacing between rows of nodes in a tree independently from their size ? If you can explain me how to see it in the demo ... Thanks Didier

	To get the diagram to recompute used space you need to handle the Diagram.TreeExpanded and Diagram.TreeCollasped events and just do a Diagram.ResizeToFitItems call within each. To adjust row spacing, change the LevelDistance on your layout object. Paul

	Add NodesExpandable="True" to the Diagram's Xaml to get the +/- buttons, which let you expand and collapse tree branches.
