base map hides the operational map

[Jitendrudulacaraju]

When I open the base map to see below an operational map. It gets on top of the operational map and hides it. How to control the position of the base map below the operational map.

How are adding your data?

It works for me when I do it in the following order:

mobileService1.CacheOpenMode = CacheOpenMode.Open;
mobileService1.CacheStoragePath = @"C:\GIS Data\EditableData";
mobileService1.Open();
map1.DataSources.Add(mobileService1);
           
SdcMapLayer sdc = new SdcMapLayer(@"C:\GIS Data\BaseData\map.navmap");
map1.MapLayers.Add(sdc);
map1.Refresh();
