I've created a TOC with a lot of help but in the end what I am doing is creating a layer based on some filters.  So what I want to do is add the layer with the filters and then if someone runs it again it removes the old layer and adds a new layer with the same name but with the new filters. Where I am having problems is removing the layer out of the Table of Contents.  So if you click on my example below and click the get results button twice you will see that my "StoresResultsLayer" is showing twice.  I only want it to show once.  So how do you remove a layer from the TOC? http://jsfiddle.net/bearcatrunner/y4hwhoge/5/embedded/result/ ...

I am trying to hide two layers in my example provided called states and counties.  I am trying to use this code to make it happen but I am getting a rootLayer reference error.  Not sure why. //SCRIPT5007: Unable to get property 'rootLayer' of undefined or null reference //TOC.js, line 906 character 3 //if (serviceLayerId !== null && serviceLayerId !== undefined && w.rootLayer instanceof (ArcGISDynamicMapServiceLayer)) {   toc.findTOCNode(StoresResultsLayer, 2).hide(); //hide States in legend   toc.findTOCNode(StoresResultsLayer, 3).hide(); // hide counties in legend I created a simple fiddle in hopes that it helps one of you smarter people to help me.  Thanks and happy Friday!

I have my layers that I load up during the initial start up of my map that you can see below.  However, I have a layer that I add in later like this:       StoresResultsLayer.setVisibleLayers([3, 4]);       map.addLayer(StoresResultsLayer); I would like this to show up in my table of contents but I would also like to allow the user the ability to turn the individual layers on and off as well.  I'm going to have one be my results for my layer and the other will be labeling for those layers.  How can I do this? Below is my code on startup for the TOC map.on("layers-add-result", function (results) { var toc = new TOC({                   map: map,                        layerInfos: [{                     layer: dlDRegionDistrictPolygons,                     title: "Boundary Files",                     collapsed: true,      showGroupCount: false,      slider: true                   },{                     layer: dlMCY_Stores,                     title: "Macys Stores",                     collapsed: true      }       ]                 }, 'sliderDiv');                 toc.startup();      toc.on('toc-node-checked', function (evt) {     // When dlMCY_Stores is turned off I want flMCY_Stores_Labels to turn off as well and vice versa.             if(dlMCY_Stores.visible == true){         //Show feature layer Labels because dynamic layers allow for infotemplate         flMCY_Stores_Labels.show();        }        else{           //Hide Labels         flMCY_Stores_Labels.hide();               }      } );    }); map.addLayers([dlDRegionDistrictPolygons,flMCY_Stores_Labels,dlMCY_Stores,flDistricts,flRegions]); ...

I have successfully been able to query my results and put them in a table and show them as points on my map thanks to a lot of help from these forums. Now what I would like to do is create another graphics layer that just has labeling for these points but I am struggling with this.  I've searched endlessly for a way to do this.  I've looked through the samples I've found something called a labellayer but I don't know how to apply that.  I would think I would be able to use something like what I did for the graphics below but instead of a symbol use text.  I created a StoresResultsLayer_Labels as you can see below.  I'm sure this is simple but it is not for me for some reason.  Any help is greatly appreciated. //My layers loaded at the start of the application but blank StoresResultsLayer = new GraphicsLayer(); StoresResultsLayer.id = 'StoresResults';   map.addLayer(StoresResultsLayer,0); StoresResultsLayer_Labels = new GraphicsLayer(); StoresResultsLayer_Labels.id = 'StoresResults_Labels';   map.addLayer(StoresResultsLayer_Labels,0); //Some of my code from my function var symbol = new esri.symbol.SimpleMarkerSymbol({  "color": [255,255,0,255],  "size": 11,  "xoffset": 1,  "yoffset": -2,  "type": "esriSMS",  "style": "esriSMSCircle",  "outline": {    "color": [0,0,0,255],    "width": 3,    "type": "esriSLS",    "style": "esriSLSSolid"  }});    var dataForGrid = []; var temp = "";     //remove all graphics on the maps graphics layer        StoresResultsLayer.clear();      //Performance enhancer - assign featureSet array to a single variable.         var resultFeatures = featureSet.features;         //Loop through each feature returned                  for (var i=0, il=resultFeatures.length; i<il; i++) {           //Get the current feature from the featureSet.           //Feature is a graphic           var graphic = resultFeatures;           resultFeatures.setSymbol(symbol);             StoresResultsLayer.add(resultFeatures);   StoresResultsLayer.show(); ...
