Have you tried my earlier suggestion?....i.e. adding a post render camera
just above the dragger.
Can be a bit fiddly to manage the scenegraph, so might be worth trying any
other ideas first.
But I can give you some code snippets if you want to try it.
Chris.

Thank you guys! I tried the idea of turning off the depth test. It works ok
but not perfect. Just as Chris mentioned, there is some rendering problem of
the dragger geometries. Anyone has idea of solving this problem? Thanks
again!

Hi Ruqin,
Just wanted to add to this as Robert and JS suggested switching off the
depth test for the dragger.
I have actually tried that and found the results "less than ideal" for the
normal dragger geometries.
The problem is that the parts of the dragger geometries may not render
correctly over each other with depth test off.

Hi Ruqin,
I had the same problem with Draggers, and the solution was to put the
dragger object in the scenegraph below a post render camera.
This works well for me as I can now also drag the selected object when it is
behind other objects in the scene. To do this you may need a version of OSG
later that 2.6 though, because I had some problems in relation to transforms
and subgraph cameras which Robert helped me to fix.
The other 'enhancement' I made was to add an autotransform node to keep the
dragger geometry the same size on the screen regardless of the size/scale of
the object.

Hi,
I got an issue about osgManipulator::dragger. When I set up a dragger,
sometime it just hide (totally or partially) inside the selected object. So,
I am wondering if there is some sort of way that I could always force the
dragger rendered on top of the selected object to make it fully visible to
user? Thanks a lot!
Ruqin
