Hi,
I studied the layout example flowlayout  included in FLOWCHART.NET

I adjusted your example with my data and the layout reacts accordingly what we need.

Then i copied exactly the same code in my project (Netdiagram) but he ignores some layout rules. I'm breaking my head now because both codes are the same only the environment is different. SO i wonder if they behave differently ?


snippet


   
           diagram.RoutingOptions.CrossingCost = 100;
           diagram.RoutingOptions.Anchoring = Anchoring.Ignore;


           

           FlowLayout flowLayout = new FlowLayout();
           flowLayout.AutoRoute = true;
           flowLayout.HorizontalGroupOffset = 30;
           flowLayout.VerticalGroupOffset = 18;
           flowLayout.NodeDistance = 8;
           flowLayout.Margins = new SizeF(2, 2);

           // define direction rules for the connector types
           FlowLayoutRules rules = flowLayout.LayoutRules;
           rules.PreferredRules = PreferredRules.ConnectorRules;


               rules.ConnectorRules.DownOriented = new string[]  {"O0" };
               rules.ConnectorRules.RightOriented = new string[] { "O1" };
               rules.ConnectorRules.LeftOriented = new string[] { "O2" };
               rules.ConnectorRules.UpOriented = new string[] { "O3" };
         


           // miscellaneous rules
           rules.NodeRules.GroupStartNodes = "START";
        rules.ConnectorRules.HorizontalBendOrientation = false;

           // arrange the flowchart and fit it into view
           flowLayout.Arrange(diagram);
           diagram.ResizeToFitItems(5);


He ignores the left /right / etc.. oriented statements, it has no effect whatever i do.

Someone know where the issues might be ?

Thanks
R.

Hello stoyo,
The code runs after postback.

Tks!

Hi,

From what I can understand from the code, it seems Flowlayout processes links by looping over the ID lists specified in ConnectorRules, and then for each ID in the list it loops over the links with the same LogicID. So if some ID is not in the list, links with that ID are ignored.

Regarding postback, it won't work when using applet mode. We haven't implemented Flowlayout in Java yet, and the values in LayoutTraits are lost during postbacks. We'll release a service version that implements LayoutTraits serialization, so at least it would allow using Flowlayout in applet mode on the server side.
