In RoadMode gray screen instead of map

Question

Hello. 

I try to develop app on the WPF, and i need use for it bing maps API. But, after including i saw that instead of the map there was only a gray background and a watermark. Working good only in Aerial mode (without label). 

The latest version of dll, everything is fine with the drivers, the key is connected normally.

Help me , please.

Thank you.

Answer 1

It sounds like there is an issue requesting the road tiles. What market are you using the control from? The WPF control is not supported in all markets.

For new applications it is recommended to use the UWP control which can be hosted in WPF applications if you need legacy support.

Answer 2

What do you mean by the word "market"? I connected the dll to my project, took the key for the maps, and called WPF Control in the XAML code. 

Answer 3

What country are you calling the service from? For example the WPF control is not supported for the China market. Road map tiles are blocked by the China firewall.  For China support you should use the UWP map control which can be hosted in a WPF app via XAML islands if you need that.

Answer 4

I use the service from Ukraine. Can I somehow change the region to check?

Answer 5

Using a web debugging tool like Fiddler may help. You can see the web request being made for the map tiles and what the response was.

You could also try using the UWP control instead of the WPF map control. UWP controls can be embedded in WPF applications using XAML islands.
