how to programatically change layout method to MDS?

Question

Hi,

I'm using GViewer() to show a simple Microsoft.Msagl.Drawing.Graph(). By default, the Sugiyama scheme is used as a layout method, but I'd prefer to use MDS. How do I change the layout method in my code. 

I tried using 

      graph.LayoutAlgorithmSettings = new Microsoft.Msagl.Mds.MdsLayoutSettings();

but it did not change the graph layout at all.

Thanks,

Gregor

Answer 1

Hi Gregor,
This should work
            graph.LayoutAlgorithmSettings = new Microsoft.Msagl.Mds.MdsLayoutSettings();
            gViewer.CurrentLayoutMethod = Microsoft.Msagl.GraphViewerGdi.LayoutMethod.UseSettingsOfTheGraph;
            gViewer.Graph = graph;

Thanks,
Lev

Hi Lev,

I am rendering the graph for web, aving it to an image, so how do I set the  Mds Layout without the gViewer?  The first line on its own does not work. Thanks a lot.
