How to hide labels in ArcGISDynamicMapServiceLayer

Question

Does anyone know how I would go about hiding labels in a ArcGISDynamicMapServiceLayer?

This is part of my code so far:

var routeLayer = ArcGISDynamicMapServiceLayer(...);
map.addLayer(routeLayer);
var drawingOptions = new LayerDrawingOptions();
drawingOptions.showLabels = false;
var options = [];
options[0] = drawingOptions;
routeLayer.setLayerDrawingOptions(options);

After doing this however the layer isn't shown on the map.

Do I need to set the renderer property for drawingOptions as well?

Answer 1

Ok this is how i solved it.

I added a renderer to drawingOptions

var sls = new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, esri.Color([255, 255, 0]), 3);
drawingOptions.renderer = SimpleRenderer(sls);

After i did that i had to enable dynamic workspaces in the service capabilities via the server manager.

Hope this helps someone.
