	Hi Our solution is likely to use several thousand nodes. My suspicion is that this may take a little while to refresh, so I'd like to show the user the progress and also allow them to cancel the Arrange. Are either of these tasks possible? I'm using a FlowLayout. Thanks Tom

	Hi, FlowLayout can run incrementally by adding only one node at a time, so you might try to use this to implement progress and cancel. Stoyan

	Thanks Stoyan, two questions on that: 1. Will it be a lot slower? 2. How would you actually do that? Thanks for all your answers so far, much appreciated

	You can do this by calling FlowLayout.AddNode a lot of times, and it will be a lot slower I suppose we could add some event that the layout class would raise to let you update a progressbar or cancel it, but can't give you a definitive date when it will be available. Stoyan

	Has there been any update on the best way to show progress to the user while drawing or laying out a large diagram? It takes on the order of 30 seconds to update my diagram on a very fast machine. Typically longer for most users. I need a reliable way to provide feedback during such long operations.

	You can assign a LayoutProgress callback to the layout's Progress property and provide feedback from there.
