Anjelina,
Same issue as the other time I helped you add a dynamic layer to the custom basemaps. You need to make sure that the basemaps are loaded before you add a dynamic layer. Also you had a require for "dom" missing in your require params.

I have 3 questions:
1- when layers are off in map service and load in web page the tools can't show any features of map( map is empty or blank) !! why? what should I do?
2- How can I add 2 or more map services?
3- Is it possible add tiled map service like flex?

1. This sample uses very limited basemaps that only cover a very limited area (not the Whole US or World).
2. Just add another ArcGISDynamicMapServiceLayer to the code.
3. Yes just use ArcGISTiledMapServiceLayer.

No, I can see layer if that layer is on by default in my web service but if the layer is off in my arcgis map the web tools don't load map!! I hope to explain it clearly and clearly

Anjelina, sorry it is still not clear at all. Maybe it is the terminology you are using. What do you mean by web service? MapService? WebMap? It would probably be best for you to provide a sample of what you are actually doing in code as your issue has to be your code use.

Hi
I have a map that consisted of many layers(fault, river, road and...).
when I publish my map from ArcMap to ArcGIS Server, if my layers(Themes) are "on" by default, when I load Dynamic Map Service in the above sample code, each layer is on, can be load and display in web page, each one is off in arc map(before publish to arcserver) that layer not show. I hope to explain clearly what I mean.
Regards

Anjelina,
I definitely do not see the same thing as you then. When I swap out the ArcGISDynamicMapServiceLayer url for one of my own and one of the layers has its default visibility set to false in the map service I still get a toggle option created in the toggle layer list.

yes I see toggle option but when I turn layer on, no things happen and layer can not be on!!

Anjelina,
Have you changed this samples basemaps to basemaps that have coverage in your area of interest?
