Guys,
I have a bit of code that attempts to create a digram completely in code-behind. It works fine if I do a Show() on the window before adding the nodes. However, if I add the nodes first, then doa show, all of the nodes are stacked on top of each other. I assume that the layout is being constrained somehow until I submit a Show command. Can you tell me how to build a diagram 100% in code behind?
Code below:
public void Process(SasLog log)
{
// this.Show(); <---- WORKS FINE.
int y = 0;
int x = 0;
foreach (var fe in log.FlowElements)
{
var rect = CreateNode(x, y, fe);
diagramModel.Nodes.Add(rect);
x = fe.Level * 150;
y += 100;
}
this.Show(); <-- DOES NOT SHOW DIAGRAM CORRECTLY
}
//Creating the Node
private Node CreateNode(double x, double y, FlowElement fe)
{
Node n = new Node();
//Custom Label property to the Node
n.LabelTextWrapping = TextWrapping.Wrap;
n.LabelFontWeight = FontWeights.Light;
n.LabelVerticalAlignment = VerticalAlignment.Top;
n.LabelHorizontalAlignment = HorizontalAlignment.Left;
n.Label = DetermineLabel(fe);
n.LabelForeground = Brushes.White;
n.LabelDisplacement = new Point(10, 20);
n.Width = 150;
n.Height = 75;
n.OffsetX = x;
n.OffsetY = y;
return n;
}
