I was wondering if there was a way to use a map that I have stored on an ESRI server in a telerik radMap. I am not very familiar with the radMap control so any help would be appreciated. I have found the documentation on using a radMap with Shapefiles, but as with a lot of documentation, it was not very helpful. Thank you.
I am assuming that by ESRI server you mean ArcGIS Server. From the documentation only Bing and OpenStreetMap are supported: http://www.telerik.com/help/wpf/radmap-overview.html
However, it appears that a custom provider can be created to use ArcGIS Server map service.
So if you are using a cached service then you would want to create a TileProvider and if you are using a dynamic map service then you should want to create an ImageProvider.
The only other option it seems is to export your data as a shapefile or KML file and load that in the control.
It appears that a UriImageProvider is provided that may work, but I do not know how the request is sent to the server for the bounding box, but you could point it the map service and include the export to png and it may work.
