I think the "Query" part of the "Generic Tasks" is close to what you want:

Subject: Re: [mapguide-users] Sql For Data Filter
I don't have a list of what the different providers support.
I have used the OGR provider, and it supports PostGIS and limited SQL.
My approach to your problem would be to start out with the layer hidden.
When you want to display the correct district, you read out the WKT of
the feature (district) you want to perform the intersection test with.
Then you update the filter on the layer to reflect this:
GeoColumn Intersects GEOMFROMTEXT('....wkt....')
Then show the layer.
You should copy the layer into the session repository before altering it.
If you want to theme it, you can create multiple copies of the layer
and apply theming to the individual layers.

Thank for your reply,
Can you pls inform me what provider support full sql syntax? I use
postgis and it seem to be not support full sql syntax.
In my case, i can't use join tables because i need spatial
relationship between 2 tables. For examples in Mapguide sample there
are 11 districts. At first time, i want to hide parcels. Then i want
to make a query to show parcels in particular distric and i want maps
show parcels which are in that query result. In this case, join
between two tables may not help me. I make use spatial relationship
such as intersects or within in this case.

That depends on the provider. Some providers supports full SQL syntax.
I can't see how you can join tables with a filter, as that is the
equvalent of the SQL WHERE construct.
You can try to setup a Join on the featuresource, but I have had
limited success with joins.
