Hi,

I am trying to use Group class to group the nodes in workflow. Finding issue with the arrows being redrawn after adding the Group node.

I have a workflow with 2 nodes already connected and i am adding a group to the workflow grouping the two nodes already connected, after resizing the group box the connection between the 2 nodes is lost and it is redrawn over the group box.

Can you provide me a sample to use Group class for the scenario mentioned above, also I need to know how to capture the nodes once after the group is added to the workflow. There may be some events that needs implemented to capture the nodes that are made part of the Group, I feel i am missing something somewhere.

Thanks in advance

What I mean by capturing nodes is to get the nodes attached to the Group box and nodes should be moved when group box is moved.

Is Group class meant to be used for that?

I have the shape nodes already added to the workflow and I want to add a group box onto the flow and attache the nodes to the group. When I move the group box I need to get the nodes moved along with the group box.

Is this possible using Group class or I need to use some other classes?

Hi,

Thanks for you reply,

I need some sample that gets the nodes from the UI within the bounds of the group box and then to attach them to the group while resizing or moving the group box.

Please let me know if any sample application available for this.

Hi Stoyan,

I was trying to see as when the diagram_NodeCreated() event fires but in our case the event is never fired and I could not get the nodes attached to the Group.

We were using older version of MindFusion Flowchart control and currently trying to use the latest MindFusion.Diagramming control.

Could you let me know if there would be any design changes compared to Older Flowchart control and latest MindFusion.Diagramming control version 5.3?

Thanks & Regards

Yes, the method is attached that I can see in the code by using += in C# code.

Yes, it is being added from code.

We have code to add group when I drag and drop group element that is a made available in toolbox.

What exactly you mean by 'adding interactively'.

I am able to fire the event but still finding problem attaching the nodes, I cannot move the nodes attached when I move the group box on the UI.

I have a class named DiagramGroup extending MindFusion.Diagramming.DiagramNode and within that I have a MindFusion.Diagramming.Group property and I am adding a Shapenode as MainItem for the group.

Now when I raise the NodeCreated event I can only send the DiagramGroup class as parameter as Diagram.RaiseCreated() takes parameter of type DiagramNode and while running thru the code I see the nodes are getting attached those are within the bounds of Group box but after the method to attach the nodes is executed the nodes on UI doesn't seem moving when I move Group box.

Can you let me know what shall be done in this case to actually attach the nodes to Group?

I got it working to see the nodes attached to the ShapeNode object which is assigned as the MainItem of Group object of DiagramGroup class.

here is the code, not sure exactly what's happening but now I can move the nodes those are attached, Can you let me know what I am doing is correct?

I am calling below NodeCreated() passing ShapeNode object that is set as MainItem of the Group object of DiagramGroup class.

void fcMap_NodeCreated(object sender, NodeEventArgs e)
{
if(e.Node is ShapeNode)


foreach(MindFusion.Diagramming.DiagramNode n in this.fcMap.Nodes)


{



if (e.Node.Bounds.Contains(n.Bounds))




n.AttachTo(e.Node, AttachToNode.TopLeft);


}
}
