Hi,

I am trying to add nodes dynamically and want to link them and see how auto layout works for large number of nodes

Used below code to add nodes dynamically

  for (int i = 0; i < 500; i++)
            {
                ShapeNode node = new ShapeNode();               
                node.Shape = Shapes.Rectangle;
                node.Visible = true;
                node.Id = "node" + i;
                node.Text = "This is node : " + i;
                DiagramView1.Diagram.Nodes.Add(node);
                           
            }

It is adding nodes but all nodes are not visible.
Now I want them to link but not able to find sample which shows how to link dynamically added nodes

Are there any samples which will guide me, I also want to apply layout to them.


Smita.

Hi,

I could add link using FindNodeById to all nodes added but diagram shows "Trial Version" as node text and only 15 nodes are visible even after giving layout

It must be limitation of trial version, Can I get extended trial version so that I can evaluate tool in better way?

Thanks for the reply

It worked

1 question about client side mode, when I use JavaApplet as a client side mode, I am not able to view the web page it opens and closes immediately

You might be reaching the default memory limit of applets if using JavaApplet mode. The 1200 nodes do not take that much memory themselves, but the XML deserialization done when loading diagrams sent from server might need more. Try setting DiagramView.JavaArguments="-Xmx512m" or a larger number to allocate more memory to the applet.

I hope that helps,

You can find it in \program files\mindfusion ... \redistributable folder. Copy it to your site and set the TemplatePath property to point to its location.

I hope that helps,

Are there any errors or warnings shown by Visio when opening the large exported file?

FlowchartLayout might need a larger layout area than TreeLayout, and could cause ImageMap mode to reach the maximum bitmap size supported by GDI+, which should show an exception in Visual Studio console. Try setting the DiagramView.MaxImageSize property to make the control split the diagram image into smaller bitmaps.
