Hi Marie,

Regarding Bezier links, when a link is initially created, its points are placed on a straight line, so it might not look as a curve until you move a related table or some of the control points. Is that the problem?

1. Perhaps they had both Style=Bezier and AutoRoute=true?

2. Yes, one of the later beta builds adds a ShouldMoveSelection virtual method. Override it to return false when GetLinkAt() returns a link at the current position, and return null from StartDraw(). This should ensure that the click only selects the link and not start any other operation.

Hi!

1) I tried with and without AutoRoute and the results are both weird to me but setting the controls points myself for the bezier is alright and will give me more control.

2) Great!!! I'll try custom handlesStyles with HitTestAdjustementHandles...

3) . I was looking in the code found by Visual Studio thinking they would match but next time I'll be more cautious .

Since all my questions have been answered, I have a new one!!!

I now have nice links once they are created & also when a node is moved. However, I want to set the Controls Points of my Bezier link when creating a new link. How can I do that? Using diagram.LinkCustomDraw = Additional? In this case, how can my code be called first? I don't want to do the actual drawing, just updating the control points as the link gets moved and then let Flowchart handle the actual drawing.
Also, in this case (in diagram.DrawLink event), what should I use as the link's start & end points? Can I use e.Origin, e.TableRow & e.AnchorIndex to get the anchor point's position (from there I'm fine) and use e.MousePosition as the link's end position? It doesn't seem to work in my case (or it could be because LinkCustomDraw is not appropriately set)...

Thanks a lot!
Marie

Hi Marie,

LinkCreating is raised for each MouseMove messages, so try to set the points from there. The LinkCreating event-args should contain the origin properties you need.

Stoyan

AllowCreating might not be raised if some of the boolean Allow* properties are disabled and the link cannot be created at the current location because of them. Try setting AllowUnconnectedLinks = true and from LinkCreating set e.Cancel = true when there is no node under the mouse pointer.

Hi,

Another question:
B) I got a crash! I was trying to route links from LinkCreating even if I didn't solve (A) yet. While routing a link (that is not created yet), I get:

NullReferenceException was unhandled

   à MindFusion.Diagramming.DiagramLink.x0d5905a18dc24aa7(Boolean x1c5ff8c3c1ac16ad)
   à MindFusion.Diagramming.DiagramLink.UpdateFromPoints(Boolean updateGroups)
   à MindFusion.Diagramming.DiagramLink.UpdateFromPoints() 

As a reminder:
A) How to fully unallow links created from thin air?

Thanks,
Marie

Hi,

A) Trying that right now .

B) I mean setting the controls points myself in diagram.LinkCreating using e.link.Origin (& others) and e.MousePosition, then calling UpdateFromPoints (this is the method that crashes).

Thanks,
Marie
