| Parameter | Description |
|---|---|
| graphID | The authoring graph's ID, accessible through Graph.ID. In case of subgraphs, this must be the root graph ID. |
Context
The active Context for the graph, or null if no active context is registered for it.
Retrieves the active Context for the specified graph.
A registered Context is considered active when its underlying session is attached. If multiple contexts are registered for the graph but none is attached, this method returns null.
The lookup is keyed on the authoring graph's ID; for subgraphs, pass the root graph's ID.
Throws ArgumentException when the provided graphID isn't valid.
// Get the active context for the graph and disable the visualization of node accents. Context current = Registry.GetActiveContext(graphID); if (current != null) current.NodeAccentEnabled = false;
