Onto your questions:
- Such functionality is not supported -- currently you can zoom either through the ZoomBar with predefined zoom steps (World, State, Region, City, Neigborhood), or mouse input, or programmatically by setting RadMap.ZoomLevel property.
- You can use the RadMap.LocationRect property to extract the desired information.
- Currently only Mercator projection is supported, however, for Q1 2011 we are planning to introduce additional projections for scenarios that use EmptyMapProvider (note that Bing Maps will still support only Mercator as this is a limitation imposed by the MS imagery service).
All the best,
the Telerik team
