i created featureLayer based on a feature collection; and i added this featureLayer to my map; then i query features by Extent and objectId and my code return list features but not set symbol of features? how to set symbol of features returned from the query feature collection featurelayer;
below mycode:
require(["esri/map",

La Sinh,
Have you tried setting the selection symbol outside/before your selectFeatures function?

la sinh,
Are you sure that you have features being selected? Have you tried to put a console statement in the selectFeatures function?

La Sinh,
SO you are saying that you do get something in the console when you have this code:
featureLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function (results) {
console.info(results);
});
