Hi.

I would like to arrange created links to node/tables bounds. Check my picture. First step (picture1) is creating 5 links from table1 to table2. They arrange it like it is shown on picture2. I would like it to have like it is shown on picture3. Is it possible?

I dont have anchorpoints defined on shapes or tables.
In case of table I dont want to use TableConnectionStyle.Rows (or Both) because of some internal restrictions from my side

How is it possible to get acces to control points of links and how to change x&y coordination (for case of developing my own alghoritm )? Because link.ControlPoints is readonly

Thanx!

But...
I have created two tables, link between these tables and
MindFusion.Diagramming.Layout.OrthogonalLayout instance:

MoOrto.Anchoring = MindFusion.Diagramming.Anchoring.Reassign (or keep)
MoOrto.BaseLayout = MindFusion.Layout.BaseLayout.Cascading


After the moving tables (one table below the second one) I want to route links depended on tables position without moving tables. It means not to keep endpoints of links on the same postion (--> picture4) - it is so logical I think
How is it possible to do this?

Autorouting is keeping endpoints (--> picture2) and OrthogonalLayout is "shaking" my tables (--> picture3).

Hi!

Shaking - I mean shapes are rearrange and I want only rearrange links Sry for vague.

Now my situation about links is:
- Dynamic = True
- SnapToNodeBorder = True
- AutoRoute = True

- Im handling node modification and there I call route for all adjacent link:

    Private Sub Diagram_NodeModifying(ByVal sender As Object, ByVal e As MindFusion.Diagramming.NodeValidationEventArgs) Handles Diagram.NodeModifying
        For Each LoLink As MindFusion.Diagramming.DiagramLink In e.Node.IncomingLinks
            Call LoLink.Route()
        Next

        For Each LoLink As MindFusion.Diagramming.DiagramLink In e.Node.OutgoingLinks
            Call LoLink.Route()
        Next
    End Sub  

After this diagram with two nodes and two links looks like --> picture1. I want it looks like --> picture2

Can you please explain it on my piece of code? Can I do it in LinkRouted event with parameter e? Am I allowed to change existing (starting/ending) control point of every link?

I have checked this forum and help file. What about:
- penalties in RoutingOptions? Some penalty for the same control point for more links?
- minimal distance between all ending points of all links on the same node
- as I read there is a problem with OrthogonalLayout in case of partial diagram layouting

So, now it works great except for arranging of (starting/ending) points on the same edge of shape. This is what Im trying to fix now.

Thanx for your advice.

Hi!
Dynamic + Autoroute + call link.route in NodeModifying event works great. Thank you!

Another and I hope last issue is on a picture. As you can see links are not overlapped but my point marks are overlapped.

I think there is any property whose intent is to set minimal distance between end points of links. Some kind of untouchable/secret area around point. Am I right? Or another your idea?

Thanx.

Hi!

The solution with anchorpoints is the best way for me, thank you Stoyo!

I checked this threads

http://mindfusion.eu/Forum/YaBB.pl?board=fcnet_disc;action=display;num=116410063...
and
http://mindfusion.eu/Forum/YaBB.pl?board=fcnet_disc;action=display;num=119507436...
1) Links are blinking while moving a shape when link.dynamic=true
Can you pls help me with this? I want to keep dynamic behavior.

2) How can I do the same control (only one link for one anchorpoint) for the origin shape? There is not raised event ValidateAnchorPoint for this shape?

Oooh, sry for my mad-brained solution

This code fix both my questions!

Private Function NumberOfLinks(ByVal IoNode As MindFusion.Diagramming.TableNode, ByVal IoLink As MindFusion.Diagramming.DiagramLink, ByVal IoAnchorIndex As Integer) As Integer
	  Dim LiTotal As Integer = 0

	  For Each LoLink As MindFusion.Diagramming.DiagramLink In IoNode.IncomingLinks
		If Not IoLink Is Nothing Then
		    Debug.Print(IoLink.DestinationAnchor.Equals(LoLink.DestinationAnchor))
		    If Not IoLink.DestinationAnchor.Equals(LoLink.DestinationAnchor) Then
			  If LoLink.DestinationAnchor = IoAnchorIndex Then LiTotal += 1
		    End If
		End If
	  Next

	  For Each LoLink As MindFusion.Diagramming.DiagramLink In IoNode.OutgoingLinks
		If Not IoLink Is Nothing Then
		    Debug.Print(IoLink.OriginAnchor.Equals(LoLink.OriginAnchor))
		    If Not IoLink.OriginAnchor.Equals(LoLink.OriginAnchor) Then
			  If LoLink.OriginAnchor = IoAnchorIndex Then LiTotal += 1
		    End If
		End If
	  Next

	  Return LiTotal
    End Function
 

It works great!

Maybe you can give some advice for speed improvement.

...to have a collection of assigned anchorpoints and checking this collection instead of IncomingLinks & OutgoingLinks collections because there is a presumption in my application that number of assigned anchorpoints is less than number of free anchorpoints.

Any idea?
Thank you again
