We are also seeing clear background instead of Geographic map.
Could you please help with steps to resolve this issue.
Thank you for your post.regarding this issue you can find the information here ,in this post.
I attached a WPF sample here.
Let me know if you have any question.
Hello Divya, thank you for getting quick response.
Is there any workaround available for version Infragistics version 17?
Also, what are plan to release updated Infragistics control without needing this workaround?
Thank you for the update. As I explained in my other post , this is an issue due to a change made by OSM, it appears they are now stricter and require referrer and user agent in the web request headers. In every web request OSM required two parameter now , its referrer and user agent , if you pass both the parameter you can make a server request and the server will load. There is no issue in the Infragistics control, Although we do have to modify our sample from SB also to update our server call, for that we do have bug logged internally.
If you are using version 17.1/17.2 then you would have to upgrade to latest supported version 19.1/19.2 since ‘AlternateDownloadHandler' handle will be available in V17.1./17.2 .
Also you should not be using the tile servers from OSM directly, you should have your own tile service so with this in mind you could find out why your tile server is suddenly requiring more information in the web requests and see if there is any workaround they can provide you.
