Move Node in HierarchicalDataSource

[ROBBE]

I have a TreeView implementation that often contains hierarchies that have large numbers of nodes in very flat structures.  While I have drag and drop working, the usability just isn't very good.  So, I'm implementing a cut/paste mechanism where the cut simply remembers the unique id of the source node and on paste of the target node, I get the source node using its id and attempt to .append(sourceNode, targetNode).

However, this doesn't seem to work.

Is this the best way to approach this or is there a different way I should approach this?

 

  $("#mnuHierarchyRightClick").kendoContextMenu({
            target: "#tvHierarchy",
            filter: ".k-in",
            select: function (e) 
            { 
                switch (e.item.id) 
                {
                    case "mnuHierarchyRightClickCut":

                         var tv = $("#tvHierarchy").data("kendoTreeView");
                         var dataItem =  tv.dataItem(e.target);
                    
                        self.setClipBoard(dataItem.ID,'Clipboard: ' + dataItem.Text);

                        break;

                    case "mnuHierarchyRightClickPaste":

                         
                        self.paste(e.target);

                        break;
                    default:
                        break;
                };
            }
        });

// called from click on context menu of the TreeView

MyController.prototype.paste = function (targetNode)
{
    var self = this;

    try
    {
       
        var tv = $("#tvHierarchy").data("kendoTreeView");

        if (targetNode == null) { return false; }

        var targetDataItem = tv.dataItem(targetNode);
        var pastedDataItem = tv.dataSource.get(self.ClipBoardPrimaryKeyID);

        self.setClipBoard(0,'');

        var pastedNode = tv.findByUid(pastedDataItem.uid);

        pastedDataItem.set('parentID', targetDataItem.id);
 
        tv.append(pastedNode,targetNode);

 
    }
    catch(e)
    {
        alert(e);
    }
 
}

I figured this out.  I could not use the targetNode passed in by the context menu.  I had to go get it again using the targetDataItem.

var targetDataItem = tv.dataItem(targetNode);

var targetNode = tv.findByUid(targetDataItem.uid);

Not sure why but this works.
