Newbie here. How do I know what the origin anchor is when a user draws a link with the mouse between 2 shape nodes? I put a tag in the origin anchor but I can't seem to get to it for the LinkCreated or LinkCreating event. Am I going about this wrong?

Node.Bounds.Y should reflect the new node position when NodeModified is raised. It should be up-to-date even while the modification is in progress (in NodeModifying event handlers).

Lets say I hae 3 vertical decision shapes that all point back to the top shape if they fail. Can I make the links merge so there is only one rather than 3 separate ones?

1. I would like to highlight the active item. How do I paint a link and shape node in different colors?

2. Can I make the anchor points larger?

3. When I allowSelfLoops and draw a link from and outgoing anchor to an incoming anchor, the link origin and destination ends up being the incoming anchor rather than from the outgoing link to the incoming link. Any ideas on this? Am I going to be able to trap for this and manually redraw it or??

Okay I have this code but the origin is considerable left of the node so the x is not right. An help on how I convert the anchorpoint.x to the correct pointf.x?

      Dim newAnchorPoint As MindFusion.Diagramming.AnchorPoint = e.Link.Origin.AnchorPattern.Points(e.Link.OriginAnchor)
   If e.Link.Origin Is e.Link.Destination Then
           'self loop - set this so it does not draw a loop over itself which is the default
           e.Link.ControlPoints(0) = New System.Drawing.PointF(newAnchorPoint.X, newAnchorPoint.Y)
           e.Link.UpdateFromPoints()
       End If

Thanks Stoyan,

This actually works:    Dim x As Single = e.Link.Origin.Bounds.X
           Dim y As Single = e.Link.Origin.Bounds.Y + (e.Link.Origin.Bounds.Height / 2)
           e.Link.ControlPoints(0) = New System.Drawing.PointF(x, y)

Now the line is being drawn as a bezier i think. I want it to be just another cascading link with my text. Any help?

Stoyan,

It's getting close. Thanks for the help. Now, the left mouse still draws an ojbect on the diagram. It is immediately discarded but this is a little sloppy. Any wa to disable this?

Hi,

DrawLinks should not let you create nodes. Perhaps you are seeing the selection rectangle? If you want to disable it, try setting AllowUnconnectedLinks = true, and calling args.CancelDrag from the LinkCreating handler if you detect that there is no node at the link origin.

I hope that helps,
Stoyan
