Map: The providers order in the visual tree is wrong when the map source of a provider is updated at runtime

When you have two providers - BingMapProvider and custom TiledProvider - and the map source of the second provider (the custom one) is changed, the updated provider is drawn under the provider defined before it in the Providers collection (the BingMapProvider).

To work this around you can call the BingMapProvider's SetMapSource() method after the source of the custom provider is changed.

// set the custom provider source
bingMapProvider.SetMapSource(bingMapProvider.SupportedSources[0]);

Hi Jason,

Thank you for sharing your solution here. I hope this would help also someone else.

As for the issue, currently this is not fixed and it isn't included in our current planning. I would suggest you to follow the feedback item so that you are notified as soon as there is any update on i ts status.

I upgraded from 2014 to 2018 and this problem still exists. However, I found another workaround due to my code order. If the BingMapProvider is inserted at position 0 *after* the custom provider has already been added, the problem goes away. I noticed this because my Bing provider is added last because I don't know which base map provider I'll be using until runtime. I confirmed this workaround works for both 2014 and 2018 versions.
