How do I stop the creation of new links, but still allow relinking of the existing links?

I’ve played with OnLinkRelinked() and OnLinkCreated() but can’t stop the creation of a new link.

Also set View.NewLinkPrototype = null with no effect.

Setting View.AllowLink = false, disables both creating new links and re-linking.

Thanks

I’m not sure why you cannot set GoView.NewLinkPrototype to null. That sounds like a reasonable relaxation of rules.

In any case, you can disable drawing of new links while allowing continued relinking of existing links by removing the tool that draws new links:

goView1.ReplaceMouseTool(typeof(GoToolLinkingNew), null);

That worked great, thanks Walter.

Now I need to restore the linking behavior. Using

goView1.ReplaceMouseTool(typeof(GoToolLinkingNew), new GoToolLinkingNew());

does not work. So, how would I restore the ability to create new links? Do I have to recreate the View?

Thanks
Jack

You can’t replace what you’ve removed.

try

goView1.MouseMoveTools.Insert(0, new GoToolLinkingNew());
