Binding data to MapElements in a MapControl in XAML (UWP)

Question

I've hit a bump in the dev of my app. I'm trying to bind data to a MapControl and MapElements.

My data is contained in an ObservableCollection.

My issues :

• Binding a geoposition to the Center property of the MapControl does nothing at all when the mode is OneTime or OneWay. When I select TwoWays, it works. But I don't want it TwoWays :)

• Adding a MapElement doesn't work when done via XAML. Either I've the type string displayed on the MapControl, either I've Nothing at all. I followed different advices from StackOverflow (ie Binding a MapIcon in XAML), but none seems to work in my case.

I'm using the latest VS2017 version, and targeting 15063 to 16299. I've already hit some bumps using the MapControl on a UWP app (differences between PC and Mobile as it seems the Mobile Component is based on Here where the PC Component seems based on Bing).

Thanks for your help :)

Yeah this is a active bug in the Binding for the control. I had this issue too, it never worked when I tried to bind the Center of the map control to a property in my viewmodel, but since I found out that it's an active issue, I created a TwoWay binding with my property with the set method of the property doing nothing like below:

private BasicGeoposition mapCenter;
public BasicGeoposition MapCenter
{ 
    get{return mapCenter;}
    set{}
}
