LinkCreating not fired until directly on top of a ShapeNode (Read 2469 times)

	I would like the ability to draw a link from one ShapeNode to another, and have the LinkCreating event fire BEFORE the mouse is directly over the destination ShapeNode. How would I go about this?

	Basically giving it a little extra area outside of the shapenode that links can be drawn to..

	Check if the AutoSnapLinks and AutoSnapDistance properties do what you need. Otherwise enable the AllowUnconnectedLinks property and LinkCreating should be raised even when the pointer is away from nodes. You can set e.Cancel = true if the event-args' Destination is null to still prevent unconnected links.

	AutoSnapLinks worked great. One thing about this however is that I am using the ValidateAnchorPoint event to determine if there are valid anchor points to connect to. In the situation where I am trying to connect to a shape node with no valid anchor points, it "snaps" to the nearest border point when I think it should not attempt to change the position at all if there are no valid anchors. Can I request this change for a future MindFusion version? I have a very small source patch I can send you if you want to see the change I am proposing.

	That should depend on the value of the Diagram.AllowUnanchoredLinks flag; try setting it to false first. If disabling AllowUnanchoredLinks does not help, please send the patch to support@mindfusion.eu.
