Hi,

Could you check if the WorkflowDesigner sample from our Windows Forms control is close to what you need?

If it is, we can port it to WPF in the next few days.

That's great 8) We'll create a WPF version next week.

Hi,
I'm evaluating WpfDiagram now. Our application should display some Process Flow (as a monitor, not as a designer). I tried to use the FlowLayout and really didn't understand how to use it. The help states that:

Workflow Graph Layout
The FlowLayout algorithm can be used to lay out flowcharts, workflow and process diagrams. It works by applying a customizable set of rules for local positioning of connected nodes relatively to each other. On a larger scale, the algorithm keeps groups of nodes separate and prevents links between the groups from crossing nodes. The FlowLayout and ProcessLayout examples included in the WpfDiagram package demonstrate two sample sets of layout rules.

I found neither example in the package. The Workflow Designer sample doesn't contain FlowLayout example as well.

Thanks.

I tried porting the definitions from the WinForm FlowLayout sample (which works well) into the wpf sample:
if (flowLayout == null)
           {
               flowLayout = new FlowLayout();
               flowLayout.AutoRoute = true;
               flowLayout.HorizontalGroupOffset = 60;
               flowLayout.VerticalGroupOffset = 35;
               flowLayout.NodeDistance = 10;
               flowLayout.Margins = new Size(0, 0);
               flowLayout.LaneType = LaneType.LaneGrid;

               // define direction rules for the connector types
               FlowLayoutRules rules = flowLayout.LayoutRules;
               rules.PreferredRules = PreferredRules.ConnectorRules;
               rules.ConnectorRules.DownOriented = "ControlFlow";
               rules.ConnectorRules.RightOriented = "False";

               // miscellaneous rules
               rules.NodeRules.GroupStartNodes = "Start";
               rules.ConnectorRules.HorizontalBendOrientation = false;
           }

I used a TreeLayout sample as base, so I drop nodes and do the following:
private ShapeNode addChild(ShapeNode node)
{
// create the new node and add it to the parent group
// so its position is updated when the parent is moved
ShapeNode childNode = new ShapeNode(diagram);
childNode.AllowDrop = true;
diagram.Nodes.Add(childNode);
// link the parent node with the child
DiagramLink link = new DiagramLink(diagram, node, childNode);
           link.LayoutTraits[FlowLayoutTraits.LogicID] = "ControlFlow";
           
diagram.Links.Add(link);

// update the counter
uniqueID += 1;
childNode.Tag = uniqueID;

// rearrange the tree
rearrange();

// select the new node
diagram.Selection.Change(childNode);

return childNode;
}

This fails with Null reference exception somewhere inside             flowLayout.Arrange(diagram);

I sent it to the support email.
Thanks.

The only place I create links appears below and I set the necessary trait there.
The xml will be of little help because the sample starts with single node and when I drag another one and call rearrange, it fails with exception.
I will send this project via email.

Thanks

Hi,
I've done what you mentioned:
1. Marked all node with "Unspecified"
2. Created an "End" node and added this type to NodeRules.GroupEndNodes.
3. I prebuilt the nodes instead of drag & drop.
The FlowLayout doesn't seem to be functional.

Please advise how can I use the wpf component to display a workflow without manual layout.

Thanks.
