This is a continuation of my thread at http://forums.arcgis.com/threads/101693-Zoom-level?p=362198&posted=1#post362198. In that thread, I reported the Zoom level in JS application. Using Jeff's approach, I added the operation layer, which is defined with deeper scale in ArcGIS Server, before I added another other layers. The problem remained is that once a basemap is loaded, that operational layer becomes invisible. However, in my SL application, it is not a problem. Is there any way to solve it? Thanks.
Using the procedure below, the problem is solved: 1) Change esri.layers.ArcGISTiledMapServiceLayer to esri.layers.ArcGISDynamicMapServiceLayer for the basemap. 2) Set the basemap opacity: 0.5. 3) Load the operation layer that can scale deeper as the 1st layer.

Jeff: Actually, it can zoom deeper than L19, and can go as deeper as that in ArcMap. I added an opcity slider for the basemap: US Streets. It looks fine. But I can't use ESRI basemap gallery, as pointed out already. Thanks anyway.
