MSAGL Graph C#

Question

Hello, I am trying to make an app with Winforms. The app uses MSAGL to visualize a graph. Can you visualize this graph in the same form as my app, i.e. not making new form for it? Thanks

Edit: I can insert the graph to the form. But, can you make sure that the graph back color is the same as the one you set before? And how about a fixed layout, i.e. the layout of the MSAGL viewer?

Hi RichardRivaldo-2611,
I made a test via Microsoft.Msagl.GraphViewerGdi you can refer to.

    private void Form1_Load(object sender, EventArgs e)  
    {  
     //create a viewer object  
     Microsoft.Msagl.GraphViewerGdi.GViewer viewer= new Microsoft.Msagl.GraphViewerGdi.GViewer();  
     //create a graph object  
     Microsoft.Msagl.Drawing.Graph graph = new Microsoft.Msagl.Drawing.Graph("graph");  
    //set graph back color  
  //graph.Attr.BackgroundColor = Microsoft.Msagl.Drawing.Color.Gray;  
     //create the graph content  
     graph.AddEdge("A", "B");  
     graph.AddEdge("B", "C");  
     graph.FindNode("A").Attr.FillColor =Microsoft.Msagl.Drawing.Color.Red;  
     graph.FindNode("B").Attr.FillColor =Microsoft.Msagl.Drawing.Color.Green;  
     Microsoft.Msagl.Drawing.Node c =graph.FindNode("C");  
     c.Attr.FillColor =Microsoft.Msagl.Drawing.Color.PaleGreen;  
     c.Attr.Shape =Microsoft.Msagl.Drawing.Shape.Diamond;  
     //bind the graph to the viewer  
     viewer.Graph = graph;  
     //associate the viewer with the form  
     this.SuspendLayout();  
     viewer.Dock =System.Windows.Forms.DockStyle.Fill;  
     this.Controls.Add(viewer);  
     this.ResumeLayout();  
    }  

The result:

You just add the Viewer with Controls.Add of your Form, like any other control
And you can change all colors
For example, I have set the background graph color to Yellow and Viewer "outside" background to Red :

graph.Attr.BackgroundColor = Microsoft.Msagl.Drawing.Color.Yellow;  

in ScrollGViewer.cs :

Brush outsideAreaBrush = Brushes.Red;
