Thanks, so much I will have to send you care package from New Orleans for your
help....lol, I was able to get things functioning correctly with a sample
project. Now I'm moving from a sample to a real world map created by our GIS
dept. My code seems to work fine (no exceptions), but it seems that the XML
selection.ToXML is not created correctly actually compared to the sample
project, only the XML shell is present. I followed the exact process in code
which should work, my real world map is less complex than the sample project.
Consisting of a single layer, map, and feature source. Below I have listed the
objects and resources setup in MapGuide. Thanks for the expert help.
Map is called "Map"
Layout is called = "Layout"
Layer is called = "ABC_Terminal"
Feature Source is called = "ABC_Terminal"
Class: ABC_Terminal

Here is the code, please note that MgFeatureQueryOptions filter is hard coded
to filter ("FeatId = " + 1) and highlight.

In the last line, try replacing:
String selectionXML = selection.ToXml();
with:
selection.Save(resService, "Sheboygan");
And instead of the JavaScript SetSelectionXml, try to do only a map refresh:
parent.GetMapFrame().Refresh();
If it does not work, can you post the string you get from "selection.ToXml();"?

Do you have any code snippets on how and when to do this? My process was taken
from andf online example provided by Autodesk and the process works when the
selection code is called from a button click and save is never called, which
leaves me to wonder.."Am I doing something wrong?" I don't think I'm even
effecting the viewer at all. Anyway...thanks for the help.
