	Hello, Stoyan! Is there any way to change direction and position of arrowhead of the link or set for example arrows at the both ends of the link?

	Hi, You can set the HeadShape and BaseShape properties to display arrowheads at both ends. You might also handle the DrawLink event and use the DrawArrowhead method to render arrowheads anywhere you'd like. I hope that helps, Stoyan

	Ok. I try to do it. Thank you. But to handle DrawLink event is not a solution for me because I want to change links from the property grid when they are already drawn in the following way: ---------> <-------- ---------- <-------->

	Do you mean you need to reverse the links' direction?

	You could either exchange the Origin / Destination values to really reverse the link, or exchange HeadShape / BaseShape to reverse only the arrowheads.

	When I set for link Base and Head shapes null (link without arrows) and save it to xml it don't set tags: BaseShape and HeadShape. After that I load diagram from xml and I see that saved link loaded as link with HeadShape = arrow.
