I have three projects here. There are Client, Server, and UserControl which contains with ArcGIS. Let me call the UserControl as UserControl map. I use the UserControl in the client. To synchronize between client and server, I created libraries which contain functions of calculating map, such as the function of GetMapPosition, GetMapDepth, etc. In the GetMapPosition, I need to use the function of ScreenToLocation. For access it, I must create the map view in my libraries class. That's why I must create the map view without XAML. Anybody have a solution for this?
