Hi all,

I have a multi layer map, most of which source their information from a spatial MSSQL server.
On top is a geometry layer illustrating the roads travelled on, along with markers for special events.
Now, basically, the only dynamic layer is the geometry layer. On reloading the map after adding an additional geometry, however, all layers are updated, though the map envelope stays the same.

Is there a way to disable reloading layers if the envelope didn't change?

This would mean a big performance increase since the map zoom level could be adjusted so that the geometries could always fit, or at least for a certain time.

The only thing I could think of is layering multiple MapImages with the "background" map being automatically adjusted to the "foreground" geometry map.
