Add Objects to a Subgraph

GoDiagram (6 and previous)

I have anther issue:

I need to create a subgraph and I need to be able to add GoObjects ( ColoredNode or anotherSubGraph) to it on the fly.
I checked your SubGraph application but in there you only add collections of objects so I tried using the GoSubgraph.Add method to add my objects but it is not quite working.

Please can you give me a ny advice.
Here is my code:
[code]
ColoredNode x1 = new ColoredNode();
foreach (Block childblock in block.Blocks)
subgraph.Add(x1);
[/code]
How can I make this simple line work.
Thanks

GoObjects (including GoNodes) cannot be shared by different GoGroups (including GoSubGraphs).

Maybe:
foreach (Block childblock in block.Blocks) {
ColoredNode x1 = new ColoredNode();
... initialize x1 appropriately according to childblock ...
subgraph.Add(x1);
}

Thanks Walter. THat helped.

I am able to add it now. I keep forgetting that in C# everything is a reference.

Well, that’s not quite true, since any type that inherits from System.ValueType is by definition a value, not a reference type.

And that is the case for all .NET languages, not just C#.
