Striped arrows

GoDiagram (6 and previous)
1

I have a simple diagram and I want to distinguish between two types of connections. I thought to create two styles of the arrows.

Is there a component of striped arrow? or any other possibility to create something like this? - - - - - - ->
or something similar? any style of arrow? (but not differences in colors)

You can set the Link’s Pen.DashStyle and the Link’s ToArrow property.

    Pen pen1 = new Pen(Color.Black);
    pen1.DashStyle = DashStyle.Dot;

    link1.Pen = pen1;
    link1.ToArrow = true;

Thank you very much! It’s exactly what I need.

but there is a problem with it. When I do a check and change the style of one arrow all the arrows in the schema get the new style and I need different types of arrows for some types of nodes.
What should I do? Is it familiar problem? or only in my project? (If yes I will search the problem by myself but if not maybe someone have a solution.)

Can you post the link initialization code and also the code that changes the style of one arrow that isn’t working? Thanks.

Yes, of course. thanks!

I have a class "DeviceLink". This class inherits from "GoLabeledLink".
I try to change the style in this function:
(The function is activated in loop when I load the schema (for all the saved links) and when the user creates new link.)
private void AddLinkToSite(InterConnectionDS.TBL_INTERCONNECTIONRow connection, GoView view) {
string fromDevName = _dsDeviceDS.TBL_NETWORK_ELEMENT.FindByNETWORK_ELEMENT_ID(connection.SOURCE_NODE_ID).NETWORK_ELEMENT_NAME;
string toDevName = _dsDeviceDS.TBL_NETWORK_ELEMENT.FindByNETWORK_ELEMENT_ID(connection.DESTINATION_NODE_ID).NETWORK_ELEMENT_NAME; DeviceNode fromDev = (DeviceNode)view.Document.FindNode(fromDevName); DeviceNode toDev = (DeviceNode)view.Document.FindNode(toDevName); DeviceLink mtnlink2 = new DeviceLink(); if (toDev.DeviceType == EDeviceType.IR || toDev.DeviceType == EDeviceType.UP) { mtnlink2.Pen.DashStyle = DashStyle.Dash; } else { mtnlink2.Pen.DashStyle = DashStyle.Solid; } mtnlink2.FromPort = fromDev.FromPort; mtnlink2.ToPort = toDev.ToPort; view.Document.LinksLayer.Add(mtnlink2); }
but it also happend when I use simple GoLabeledLink in the event:
private void goView1_LinkCreated(object sender, GoSelectionEventArgs e) { GoObject obj = e.GoObject; GoLabeledLink link = obj as GoLabeledLink; if(..............) { link.Pen.DashStyle = DashStyle.Dash; } else { link.Pen.DashStyle = DashStyle.Solid; } }
When a new link is created there is a check and if its DashStyle is changed all the existing links in the schema get the new style.

You can’t change Pen attributes for a pen already in use.

Create a "new" Pen and set link.Pen to that.
