Zoom to view all items? #51

Closed mennowo closed 4 years ago

mennowo commented 4 years ago

Hello, first off: thanks for a great control! Easy to use, and it has always just worked. A question: is it possible to make the map zoom in a way so that a given range of GPS coordinates will become visible? Thank you! Greets, Menno

Sure, there is a ZoomToBounds method in MapBase.

Ok, thanks! Now I am trying to databind to the BoundingBox dep. property on the Map control. Is that supposed to have the same effect? Setting it to a new value seems to no influence the view. Thanks again.

Not sure what you mean. There is nothing like a "BoundingBox dep. property on the Map control".

Map inherits from MapBase, which in turn inherits from MapPanel. The latter has a DependencyProperty BoundingBox, which I tried databinding to. However, I now got it working using the ZoomToBounds method you mentioned, wrapping that in dependency property in a user control. Thanks again! Greets, Menno

That is an attached property, which can be set on child elements of a MapPanel (e.g. an Image element in a MapImageLayer), but not a MapPanel itself. The Map element does not have a BoundingBox property.
