ArcGIS.Core.Data.NetworkDiagrams Namespace / NetworkDiagram Class / SaveLayout Method
The NetworkDiagramSubset of the geometries to save.
Indicates whether the vertices are kept when reconnecting the edges.
Example Version

SaveLayout Method
Saves the layout of diagram elements. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
public void SaveLayout( 
   NetworkDiagramSubset subset,
   bool keepVertices
)

Parameters

subset
The NetworkDiagramSubset of the geometries to save.
keepVertices
Indicates whether the vertices are kept when reconnecting the edges.
Exceptions
ExceptionDescription
A geodatabase-related exception has occurred.
Remarks
Example
Change the Layout of a Network Diagram
public void DiagramElementQueryResultAndNetworkDiagramSubsetClasses(Geodatabase geodatabase, DiagramManager diagramManager, string diagramName)
{
  // Retrieve a diagram
  using (NetworkDiagram diagramTest = diagramManager.GetNetworkDiagram(diagramName))
  {
    // Create a DiagramElementQueryByElementTypes query object to get the diagram elements we want to work with
    DiagramElementQueryByElementTypes query = new DiagramElementQueryByElementTypes();
    query.QueryDiagramJunctionElement = true;
    query.QueryDiagramEdgeElement = true;
    query.QueryDiagramContainerElement = true;

    // Retrieve those diagram elements
    DiagramElementQueryResult elements = diagramTest.QueryDiagramElements(query);

    // Create a NetworkDiagramSubset object to edit this set of diagram elements
    NetworkDiagramSubset subset = new NetworkDiagramSubset();
    subset.DiagramJunctionElements = elements.DiagramJunctionElements;
    subset.DiagramEdgeElements = elements.DiagramEdgeElements;
    subset.DiagramContainerElements = elements.DiagramContainerElements;

    // Edit the shapes of the diagram elements - left as an exercise for the student
    TranslateDiagramElements(subset);

    // Save the new layout of the diagram elements
    diagramTest.SaveLayout(subset, true);
  }
}
