FeatureLayer does not return hatched symbols

[SantoshV]

Hi,
I am querying and adding a FeatureLayer onto my Map

FeatureLayer fl = new FeatureLayer();
fl.URI = "http://Server1/ArcGIS/rest/services/BOUNDARIES/MapServer/0"
fl.ID = "Boundary1";
MyMap.Layers.Add(fl);

When I add the featurelayer to the map the symbology which I set in ArcMAP(hatched symbols) does not appear in  my map but it    shows solid colors
I want the hatched symbols in my map

Please guide...
