anchorpattern not saved in DiagramView1.Diagram.SaveToFile (Read 2506 times)

	I have made an achorpattern with scripthelper. My nodes have this anchorpattern, this works fine. When I SaveToFile and then LoadFromFile my anchorpattern isnt there anymore, and the nodes have lost their anchorpoints.' Is this by design ? How to keep my anchorpattern?

	If you specify an Id when creating the AnchorPattern, only its Id is saved when serializing nodes and the control relies that a pattern with the same Id exists when loading the file. If you specify an empty string, the full AnchorPattern definition should be saved in the file, so try using ScriptHelper.createAnhorPattern(""). I hope that helps, Stoyan

	Thanks for your help, but I don't realy understand. I made the anchorpattern with ID. When I saveToFile the anchorpattern still exists ? And when I then load it, why would it be gone? When the Diagram is saved with anchorpattern-ID, when should I create a new anchorpattern, before or after loading the diagram? What I am also confused about: When I make an anchorpattern in code-behind with ID = "_PAT", can I use this in jscript with scriptHelper.anchorPatternFromId("_PAT") ?

	If you create AnchorPattern with ID on the client, it will be lost after postback if it's not registered on the server too. I.e. even before the code reaches the server's SaveToFile call, the control reads the diagram content from some XML submitted by the applet - there's only the ID string saved in that XML. So you will have to create corresponding AnchorPattern definitions in the server's page_init event to preserve custom AnchorPatterns coming from the client, if they have an ID set. I hope that helps, Stoyan
