Hi,

I have DynamicMapService published on server with default labeling on for two layers (Manhole and Parcel).

I have menu "Labels" next to each layer in TOC of my application.

I have tried this below code when you click on "Labels" menu :

topic.subscribe('layerControl/showLabelPicker', function (event) { 
 var drawingOptions = new LayerDrawingOptions();
 //also tried below line to get existing drawing options but first time event.layer.layerDrawingOptions is undefined
 //var drawingOptions = event.layer.layerDrawingOptions; 
 drawingOptions.showLabels = false; 
 var options = []; 
 options[event.subLayer.id] = drawingOptions; 
 event.layer.setLayerDrawingOptions(options); 
});

This is what I get in event.

Label is getting turn on/off but it switch the labeling for @those two layers (Manhole and Parcel). for example :

  1. First I click on Foul Sewer Manhole layer Labels menu to Turn off the Labels - It is working fine
  2. Now, I click on Parcel layer Labels menu to Turn Off the labels - here it switch the label, it turn off the Parcel layer label and turn on label for Manhole
  3. Again If i click on Foul Sewer Manhole - it turn on Parcel label and so on.

Any idea how to toggle label of DynamicMapService service published on server with default labeling on ? 

if layer labeling is On/Off then toggle labeling of layer ?

Thanks,
