Currently the Drag and Drop functionality does not work for TreeView nodes that are set to navigate on click. As a workaround, you could consider using a conditional template, which will display a link if the node's purpose is to navigate and only its text if it is not. This way clicking on the link itself will navigate, but the node can still be dragged/dropped if you click on the span element that holds the anchor. Here's a sample dojo
that demonstrates this approach. Note that I applied a CSS rule that makes the span element mentioned above wider so that it is easier to click on it (instead of on the link it wraps) and drag it.
