Cell tooltips should work with this version:
https://mindfusion.eu/_temp/wpfdiag_celltips.zip

I hope that helps,

Expand the References branch under Solution Explorer and select the mindfusion.* assemblies. Now look in the properties window and make sure the "Use specific version" property is set to false for them. Or perhaps just remove the references and add them anew using the new assemblies.

I hope that helps,

If the message is shown coming from LC.EXE, edit licenses.licx and set PublicKeyToken=null; then it should work for any version. Or delete the file and it should be generated next time you rebuild.

I see now that the behavior described above may be caused by my implementation of the diagram_ValidateAnchorPoint_Event.

But a new problem:
I have a myTableNode class with two rows that contain one AnchorPoint each, a red AnchorPoints in the upper row and a blue AnchorPoints in the lower one. The Colors are stored in the AnchorPoint.Tag and I want to initialize the DiagramLink with the appropriate color of the AnchorPoint when creating a link.

I have the diagram property SnapToAnchor = OnCreateOrModify and I use the diagram_LinkCreating event to transport the color from the AnchorPoint.Tag to the DiagramLink.Stroke.

When creating a link by dragging the mouse inside the myTableNode the Links origin already snaps lets say to the blue lower AnchorPoint without raising the
diagram_LinkCreating event. When I now accidentally pass the upper red AnchorPoint while I am leaving the myTableNode the diagram_LinkCreating is raised the first time with a MousePosition pointing to the wrong red AnchorPoint. (My Link has already snapped to the blue AnchorPoint before.)
In the end of the day the diagram_LinkCreating event serves the wrong color and I have a red link connected to a blue AnchorPoint.

I need an event that is raised by the time the SnapToAnchor property takes action so that I am able to identify the AnchorPoint where the link has snapped to.

Do you see a chance to control that?

@Meppy
I must forbid links between different colors. If the link starts from a red anchor I must set the link's stroke to red and allow only connections to red destination anchors.

Example:
I always link cells of TableNodes. There may be a TabelNode with 10 outgoing anchors, 7 red and 3 blue. The second TablNode may have 10 incoming anchors, 4 red and 6 blue. It is allowed to connect each of the 7 outgoing red anchors of the first TableNode to each of the 4 incoming red anchors of the second TableNode. But not to one of the 6 blue incoming anchors.

Thanks Meppy,

Thanks for your help. It works the way I want to use it.

When I remove a DiagramLink and create it later on again in the MyTableNode via
Parent.Factory.CreateDiagramLink(oldLink.Origin, this)
the link somatimes has a different shape.

Before:
______
|______

After:
______|\
\____
It has some diagonal segments.
Do you know why?
How can I recreate a link with the same shape as before?

Pontius

My links always have the PolyLine Shape never Cascading. I do not change the Shape.
The diagonal segments always appear wether I use the GridRouter or the QuickRouter.

I recreate the links after a user interaction where the number and position of AnchorPoints of the TableNodes may have changed. That's why I can not create the links by reusing old ControlPoints.

Original A:


After programmatically recreated:


Original B:


After programmatically recreated:


In both simple cases above the AnchorPoints have stayed the same. So the result afer recreating the DiagramLinks programmatically should be the same too I think.

There are also problems with LinksCrossing.Arrow.
Sometimes there are no Arrows where there should be Arrows:


Somtimes Arrows reside while the other crossing DiagramLink was removed:
