Thanks for reply Dominique BROUX I Have 9 set of layers set to WGS_1984_UTM_Zone_44N projection system. My lat long values at a perticular point are 78° 12' 929"E and 8° 46' 5.791N this is perfectly fine.. On Adding bing maps to my current map My lat long values at that point are completly different.. How will i get the exact lat long values.. On Adding bing maps my overview map is blank. Map OverView Map How will i project bing maps to WGS_1984_UTM_Zone_44N

Could you give more infos about what you mean exactly by that?
 
Adding a TileLayer means that your map is now using the BING web mercator projection.
Then ArcGIS server should project on the fly all your dynamic layers in order to get a correct map.
