Another couple of questions on DynamicLayers
1. In the ItemsRequestEventArgs you get the UpperLeft and LowerRight locations. What do these actually signify. They aren't the locations of the corners of the visible map, as the ItemsRequest seems to be only called when we move over a ZoomGrid boundary. I seem to always get a LocationRect of a large area even when zoomed in, so I end up having to give more items then I want to.
2. The second question is how does the ZoomGridList work, and how does it have an effect on point 1.
DynamicLayer dynamicLayer =
ZoomGrid(2, 2, 3));
ZoomGrid(4, 4, 9));
I know you give the latitudes, the longitudes and the zoom, but how do they work? My gut reaction is that you are defining squares that will ask for items as they come into view, and these squares are associated with the zoom layer. If this is the case, then I would expect the ItemsRequest method to be called as the map is panned?
Hope you can straighten me out on how the dynamic layer actually works so that I can optimise my display
