Probably, simple question that I cannot find answer from API reference:
After applying custom symbology
https://developers.arcgis.com/javascript/3/jsapi/arcgisdynamicmapservicelayer.html#setlayerdefinitions
app.anyLayer.setLayerDrawingOptions(optionsArray);
how to restore default symbology for it?
You can restore the original symbology / renderer etc by setting the LayerDrawingOptions to null.

Piterson,
You keep a copy of the original renderer and then restore it, or you remove the layer from the map and re-add it. There is no restore render option.
Robert,
Thank you for response.
Please provide example code how to "keep a copy of the original renderer".
Thank you thejus! I will try.
