Hello,
You need to refresh mapFrame.
Look at this:
1. Put this in head of file
<script type="text/javascript">
function select(xml)
{
parent.mapFrame.SetSelectionXML(xml);
parent.mapFrame.ZoomSelection();
}
</script>
...and this at the end of file...
map.Save();
RegisterStartupScript("start", "<script>select('" + selectionXml +
"');</script>");

Subject: [mapguide-users] Features Are Not Highlighted
Hi,
I have written the following code to select/highlight the features on
the map.
MgMap map = new MgMap(myConnection);
map.Open("MyMap");
MgFeatureQueryOptions queryOptions = new
MgFeatureQueryOptions();
queryOptions.SetFilter("ID<4");
MgLayer layer = map.GetLayers().GetItem(0) as MgLayer;
MgFeatureReader featureReader =
layer.SelectFeatures(queryOptions);
MgSelection selection = new MgSelection(map);
selection.AddFeatures(layer, featureReader, 0);
selectionXml = selection.ToXml();
The code runs perfectly. And in viewer it also shows that 2 Features
Selected. But features are not highlighted on the map.
Please assist...
Thanks & Regards,
Ravinder
