Hi All,

I am trying to implement drag and drop in NSOutlineView.

I have create NSOutlineView connected it through Interface Builder. I have also set its delegate. and then I registered the type of drag. then I implem writeRows , validateDrop & dropaccept Method. But When I drap a row, control only goes to WriteRows and it is not going inside ValidateDrop and accept because of which I am not able to drop row. Any kind of help would b appreciated.

Thanks Sourabh
