Hi Ben, 
  
 I tested with you code but cannot get the exception, could you please send your sample to us to have a test? 
  
 Thanks,

 Hi,


 


I attached sample eith Style problem for you.


I don't know this will help you or not, when I'm using version 6.x (even without Style) in the design mode It doesn't show the control.


'Error 1 The name "WpfMap" does not exist in the namespace "clr-namespace:ThinkGeo.MapSuite.WpfDesktopEdition;assembly=WpfDesktopEdition".


but when I'm running the application, it's work fine(obviously without Styling).


Regards,


Ben

Thanks Edgar, 
  
 It’s working now, just can you please say why we need that ‘Term of use’ for Style to work? 
  
 Regards, 
 Ben

#6

Because we just want to display one BingMaps Logo and license on the map even it's multi-tile mode, it'll be enabled when using bing maps, our development team is still working on it to find a better way to display it, maybe it'll be not necessary in the coming days. 



Regards, 



Edgar

Hi Edgar, 
  
 I found another issue with Style, if you style the map then the SimpleMarkerOverlay will not work.

Hello Ben, 
  
 Thanks for your further information, we will check this part and make sure it will be fine. 
  
 As soon as we finished this, we will post in the forums. 
  
 Regards,
