    No, there is no event.

    You would have to do an inline override onNodeDrop (in dropConfig), that checks the return value from the original onNodeDrop.

    Hi everyone

    To do some processing on a tree node after an invalid drop, there is a method in Ext.tree.TreeDragZone, override that method :

    Code:
    Ext.override(Ext.tree.TreeDragZone, {
    
            afterRepair:function(){
                // Code to be processed on node after an invalid drop
                this.dragging = false;
            },
    
            getRepairXY : function(e){
                return false;
            }    
    });
    Hope that helps somebody.
    Regards
