Adding to MapShapeLayer DataSource collection doesn't redraw the new bubble

[George DAlessio]

When updating or adding to the Markers bound collection the map correctly displays the updates and new markers.

If the DataSource bound collection is changed when using bubbles, the tooltip reflects the change for the SizeValuePath field but the actual size doesn't change. 

If the DataSource bound collection is changed by adding a new element, the new element is not drawn.

I couldn't find an example of adding new elements at runtime to the MapShapeLayer DataSource collection when using MapShapeLayer.BubbleSettings.

Thanks for your help

Hi George,

We have checked and we are able to replicate the reported scenarios “dynamically changing DataSource bound collection does not draw the new element”, and “dynamically changing the SizeValuePath field of the DataSource bound collection reflected in tooltip, but the bubble size does not change” in the .NET MAUI SfMaps control from our end. We have logged issue report for the same. We will fix this issue and will include the fix in our upcoming weekly NuGet release update, which is expected to roll out on July 2, 2024. We appreciate your patience until then.
