Diagram layout problem with HierarchicLayoutManager
Hi,
i have the following problem. I have an small example with a main node which has 3 parent nodes and 2 child nodes. With the HierarchicLayoutManager i want to layout the diagram automaticly, but the layout result is unexpected.
My current layout is as follow
But what i want is the following
The automatic layouting for the child nides is correct, but the layouting for the parent nodes is not correct in my example.
Any Ideas what i'm doing wrong?
Attached is a small code example.
Thanks and best regards,
Thomas
private void TestSyncfusionDiagramForm_Load(object sender, EventArgs e)
{
diagram1.Model = new Syncfusion.Windows.Forms.Diagram.Model();
// Create Main Node
var mainNode = new Syncfusion.Windows.Forms.Diagram.RoundRect(0, 0, 100, 70, MeasureUnits.Pixel);
mainNode.Labels.Add(new Syncfusion.Windows.Forms.Diagram.Label(mainNode, "Main"));
mainNode.FillStyle.Color = Color.FromArgb(255, 0, 0);

// Create CHild Nodes
