Attach a drag event handler to the treeview, and set the scrollTop of the element that is scrollable depending on the drag position.

for example if the treeViewHolderDivEdit (below) is your container of the treeview you can do below.

treeview.bind("drag", function (e) {

     var targetDataItem =  treeview.dataItem(e.dropTarget);
     if(targetDataItem != null || targetDataItem != undefined)
     {
             if(targetDataItem.text == "Root" && e.statusClass == "insert-top")
             {
             e.setStatusClass("k-denied");
             }
            //  $("#status").html(e.statusClass + "  "+targetDataItem.text );
     }
       var y = e.pageY - $("#treeViewHolderDivEdit").offset().top;
       $("#treeViewHolderDivEdit").scrollTop(y);

 });
