    I need to implement drag and drop on a treeview in such a way that it should allow drag and drop only between same level of nodes.

    Hi Stephen,

    Here is the sample code which I tried based on your scenario.

    protected void RadTreeView1_NodeDrop(object sender, Telerik.Web.UI.RadTreeNodeDragDropEventArgs e)
        RadTreeNode sourceNode = e.SourceDragNode;
        RadTreeNode destNode = e.DestDragNode;
        RadTreeViewDropPosition dropPosition = e.DropPosition;
        if (sourceNode.Level == destNode.Level+1)

    Hope this helps.
