Hey,

I have a custom node class which inherits CompositeNode and are used within a TreeLayout. As part of this, I now want the "expandable" facility adding so I set the Expandable property of all nodes to be True but the +/- icons did not appear. I've since set what I think are all of the other related properties of the Diagram object but they're still not showing.

I had a search on the forum and found a thread where you recommended overriding the "drawLocal" or "Draw" method in the custom class (I don't currently override either) and calling "DrawManipulators" from it. I've tried this and my nodes still aren't showing the +/- icons. I must be missing something very obvious. Any ideas?

Cheers,

Rich

Hi,

Adding this to the examplesListBox_DoubleClick handler in Scripting sample project showed the +/- icons correctly:

...
diagram.LoadFromXml(document);
OnDiagramLoaded();
// new code
foreach (var node in diagram.Nodes)
	node.Expandable = true; 

Please make sure you are setting Expandable and not Expanded, or otherwise attach a test project reproducing the problem.

Cheers,
Stoyan
