DiagramNodeCollection

Hello,

i am confused with my DiagramNodeCollection.
I have a collection with 5 nodes and i insert one more:
Code
Select All
int i = 2;
ShapeNode node = new ShapeNode();
myDiagram.Nodes.Insert(i, node);


Now i get the position of my node:
Code
Select All
int pos = myDiagram.Nodes.IndexOf(node);


pos is not 2, it is 5. My Node is in the last position, instead of position 2.

Is there a problem with DiagramNodeCollection, or do I have a problem with my head Smiley

Hi,

That would work if you were using a standalone DiagramNodeCollection, but the diagram's instance is a bit strange. Its Insert and Add methods raise an event that passes through the undo manager and adds the node both to diagram.Items and diagram.Nodes, but your index is lost in the process. We can try to add support for insertion too, but don't dare touching that code just now before the release Smiley

Hi Stoyan,

thx for this quick hint.
I created a "workaround". It's fine.
