<pre wrap="">Where can I find code examples regarding filter on the run-time layer?
I post my code used:
String whereClause = "FG = '3'";
String layerNameDaFiltrare = "par10";
MgFeatureQueryOptions queryOptions = new MgFeatureQueryOptions();
queryOptions.SetFilter(whereClause);
MgLayer layer = (MgLayer) map.GetLayers().GetItem(layerNameDaFiltrare);
MgFeatureReader featureReader = layer.SelectFeatures(queryOptions);
Thanks for your reponse.

<pre wrap="">You must set the filter on the RuntimeLayer, not the LayerDefinition.
Also, look in the server log for clues.
There is a quirk in MapGuide, that it will render the entire layer
without filters, if the filter fails.
I'm not sure you get a log message in that case, but start out with a
simple filter like:
ID = 3

<pre wrap="">Hi,
I would filter features in the viewer, how can I do? I filter with the
web API by SetFilter, but I do not see the effect on the map
although I refresh the map.
Thank you for your help.
