	Hi, I have created an diagram that consist of node and the link. my problem is that when an link overlaps the node, i am unable to select link from the overlapped part. so when i click on link in the overlapped part node gets selected while i want to select the link. is there any way that make the link on front? Thanks, Ayush Neema.

	Set HitTestPriority = ZOrder. I hope that helps, Stoyan

	Hi stoyo, setting this property works fine when i have single link overlap a single node. But when there are two links overlap a single node, the behavior is unexpected as i select one link and other link gets selected. i have send you the image through mail for reference. Thanks Ayush Neema

	What LinkHitDistance value are you using? The hit-testing code returns the first link it finds within that distance, rather than enumerating all links and returning the closest one, so try setting this to a smaller value, such as 2-3 points.

	Hi stoyo, i set the diagram.HitTestPriority = HitTestPriority.ZOrder; This allow me to select a link that overlaps a node. I am capturing diagram_LinkClicked and diagram_LinkDoubleClicked event. But problem is that when two link overlap a node, i am not getting the expected link in that event. How and where i can specify the distance?

	Set diagram.LinkHitDistance = 3;
