I want to make expand arrow on grid just to expand child items not to select this row.
I was trying to attach to event "detailExpand" but there I can only clear selection which I don't want to happen.
The hierarchy expand/collapse button shouldn't select the row. At least it doesn't on this demo here - http://dojo.telerik.com/@rusev/IPEtU
Problem was solved by updating Kendo to the newest version.
