Hi

We have a big problem after purchasing Diagramming and running into a System.OutOfMemoryException when trying to perform a LayeredLayout.Arrange on a diagram with 43 nodes. I tried the suggestions in other similar posts without success. I even replaced the Mindfusion demo diagram nodes with mine, resulting in the same error message...

Please help! We need to go into production with this and although all was fine with most diagrams so far, this is a nasty surprise.

Thanks much in advance.

I remember there was a similar problem with the initial implementation of the EnforceLinksFlow property. It depended on the number and length of cycles in the diagram. We have implemented a more memory-efficient algorithm in the next release. So try using a newer version of the control or disable EnforceLinksFlow.

I hope that helps,
