OrgChartNodeDropEventArguments make LinkButton onClick false on first click

[Peerayu]

Hi, I'm using Telerik 2014.1.403.45. I have the problem with the LinkButton in my RadOrgChart node.

I put RadOrgChart in RadAjaxPanel. there are the LinkButtons in OrgChart Nodes. LinkButtons work correctly after page_load.
However, if I dragged and dropped the node and then clicked on a LinkButton, it will only do postback to page_load but no CommandEventArgs . The events of the LinkButton only works on the second click.
