[mapguide-users] make query on the fly

[erictsn at cadbeyond.com]

Hi All

In the application there is two core layers; layer A is initially displayed
in the map and can be selected. How I can make a query which uses the
selected feature of layer A? and then the Layer B will be highlight those
feature automatically & on the fly. Can I do that? The $SelectionString
shows the selected feature ID. It can be used to query the feature of Layer
B.
