ExpandButtonPosition not working with custom nodes (Read 2382 times)

	I am trying to change the ExpandButtonPosition in a diagram containing custom nodes so that the expand button is not overlapping links in a horizontal tree layout, but it has no effect and the button is always positioned outer right. Do you have any suggestions why this might be the case? Using version 1.7 Thanks in advance! Andr�

	It worked fine in our test with ShapeNodes, TreeViewNodes and types derived from them. Could you send to support@mindfusion.eu a sample project that reproduces that? If you are loading a diagram file before running TreeLayout, note that the property value will be read from the file too. Stoyan

	Try in in the Tutorial3.sln, I can reproduce it there as well. (I basically followed that tutorial line by line for my node type). The changes I made to Tutorial3 to reproduce this was to set ExpandButtonPosition="OuterLowerLeft" on the diagram and to set Expandable=true on the two nodes when creating them.

	The expand icon is placed according to that property at initialization time only if the node's Diagram is known then. Afterwards, it is updated when the node's Bounds changes. So you could either implement the DiagramNode(Diagram) constructor and use it to create the nodes, or set node.Expandable or Bounds after calling diagram.Nodes.Add(node). I hope that helps, Stoyan

	Setting Expandable on the nodes after adding them did the trick, thank you!
