Reoder Nodes and Update Database & Disable Drag Drop per node?

[Daniel]

First, i have been looking a the examples on drag and drop and see how I can reorder the nodes. In my database I have an ORDER field that determines the order of records when displayed. How can I keep track of which nodes have been reorder so I can update my database?

Second, I have been trying to figure out how to disable dragging / dropping per node. Here is my structure:

Project
     Photo Set 1 (Disable Drag and drop and reorder)
          Photo 1 (Image with Thumbnail)
          Photo 2 (Image with Thumbnail)
     Photo Set 2 (Only Allow reordering of child nodes)
           Photo 3
           Photo 4

HEre is the treeview object on the ASPX page:

 

<

telerik:RadTreeView ID="rtvProjects" runat="server" EnableDragAndDropBetweenNodes="true" EnableDragAndDrop="true" OnNodeDrop="RadTreeView1_NodeDrop">

</telerik:RadTreeView>

I am creating the nodes problematically in the VB code behind. I tried setting the AllowDrop/AllowDrag per node, but it still lets be drag and drop between nodes and into the nodes.

I can give you all my code, if you need, but let me know if this makes sense.
