Highlight anchor on mouse over

I have a bunch of custom drawn anchors i need to highlight when the mouse hovers over them.

Unfortunately there is no mouseover event on anchors and the Diagram.GetItemAt() does not trigger on anchors.
Is there any other way I can accomplish this?

Try using the GetNodeAt overload that takes a threshold argument, and then the GetAnchorAt method from this post -

http://mindfusion.eu/Forum/YaBB.pl?board=wpfdg_disc;action=display;num=125049956...

You must use the RectangleF and PointF types instead of the WPF's Rect & Point method shown in the post above.

I hope that helps,
Stoyan

Perfect!!  That would work..
Any idea how to force a redraw of the anchor/node?

(I'm testing the component, so it might be quite basic questions I have)

Try with diagram.Invalidate(node.getRepaintRect()).

I hope that helps,
