Hi , no success yet im already making some sort of save for the links (old code), if i wouldnt they would all be lost would’nt they ?There is one other thing . the line becomes different than the original diagram i.e. breaks in several mid points it decides by it self , only when the next node has open links , when the only the very first node in the diagram has open links the error does’nt happen when changing the template!
Can you think of something that can cause it ?

about your question , "
Are you using the Route class for both (or all) Link DataTemplates"
how do i make sure my second template is using Route.cs ?

Thanks

i also noticed that in route.cs there are methods like ComputeMidPoint , ComputePoints .
after my points assignment (in order to keep the points location) as follows :

  foreach (Link link in DiagramForPrint.Links)
            {
                NELink linkData = link.Data as NELink;
                if (linkData == null)
                {
                    continue;
                }

                link.Route.Points = linkData.Points as IList<Point>;
            }

the function ComputeMidPoint hits the breakpoint again !

this haapens because of this code in Route.cs:

  public Point MidPoint
        {  //?? change to be DependencyProperty
            get
            {
                if (Double.IsNaN(_MidPoint.X) || Double.IsNaN(_MidPoint.Y))
                {
                    UpdatePoints();
                    <b>_MidPoint = ComputeMidPoint();</b>
                }
                return _MidPoint;
            }
            private set { _MidPoint = value; }
        }

Ok , I found it !!! finally …

the last post i wrote got me to the conclusion its not right that points calculation inside Route.cs comes after my points assignment.

you see, this was my code :

 void DiagramForPrint_LayoutCompleted(object sender, DiagramEventArgs e)
        {
          DiagramForPrint.LayoutCompleted -= DiagramForPrint_LayoutCompleted;
            foreach (Link link in DiagramForPrint.Links)
            {
                NELink linkData = link.Data as NELink;
                if (linkData == null)
                {
                    continue;
                }

                link.Route.Points = linkData.Points as IList<Point>;
            }

            if (!IsPoligon || PrintAreaNode == null)
            {
                FitAll();
            }          
            OnDiagramForPrintCompleted();            
        }

the reason for unregistration of the function was made because OnDiagramForPrintCompleted inits a timer , and when initialized more than once it caused problem so unregistration was the solution that time. i didnt think that Route.cs methods will continue to run after layout is complited but apperantly they are.
changed my code to this (very dumb change) :P

void DiagramForPrint_LayoutCompleted(object sender, DiagramEventArgs e)
        {          
            foreach (Link link in DiagramForPrint.Links)
            {
                NELink linkData = link.Data as NELink;
                if (linkData == null)
                {
                    continue;
                }

                link.Route.Points = linkData.Points as IList<Point>;
            }

            if (!IsPoligon || PrintAreaNode == null)
            {
                FitAll();
            }

            if (!timerActivated)
            {
                OnDiagramForPrintCompleted();
                timerActivated = true;
            }
        }

thanks for all the curviness help (and more) ,
and have a nice week.
