Excellent. Glad to help. Please consider mark this thread as "Answered" so other people may find it helpful. Thanks. ... View more

I am not sure I understand your question clearly. If you like to query a subset of a layer data, set query.where to limit the result based on the attribute values. That's about the equivalent of definition expression if using Query. If you do need to use the real definition expression as used in ArcMap, create a FeatureLayer for the layer you like to query, and then set definition expression like the below sample: require(["esri/layers/FeatureLayer", ...], function(FeatureLayer, ...) {     var featureLayer = new FeatureLayer("rest/url/of/the/layer",{         mode: FeatureLayer.MODE_SELECTION,         outFields: ["*"]     });     featureLayer.setDefinitionExpression("STATE_NAME = 'South Carolina'");     ... }); You can further query against the featureLayer using featureLayer.queryFeatures. Hope it helps. ... View more

Do two things: 1. Add "dijit/registry" to the dependency list, and use registry as the alias. 2. Change:  var grid = dom.byId('grid');     To:  var grid = registry.byId('grid'); ... View more

To include ESRI basemaps, make sure showArcGISBasemaps set to true when creating basemapGallery. If you like to only include subset of ESRI basemaps or like to reorder the basemaps in the gallery, you can create a basemap for each type, and add to the gallery in order. Below is the sample for including the esri basemaps and adding yours at the end. var basemapGallery = new esri.dijit.BasemapGallery({   showArcGISBasemaps: true,   map: map }, "basemapGallery"); var basemapLayer = new BasemapLayer({     url:"url/of/empty/basemap/mapservice" }); var emptyBasemap = new Basemap({     layers: [basemapLayer],     title: "Empty Basemap",     thumbnailUrl: "url/of/empty/image" }); basemapGallery.add(emptyBasemap); basemapGallery.startup(); ...

Am I creating an ArcGISTiledMapServiceLayer? I would suggest to publish the empty map service as cached one, and DEFINE the scale levels exactly the same as any esri basemap, but do NOT create the tiled images. The ArcGIS Server will recognize it as tiled map service. The sample code explains what I meant assuming using AMD code style. var basemapLayer = new BasemapLayer({     url:"url/of/empty/basemap/mapservice" }); var emptyBasemap = new Basemap({     layers: [basemapLayer],     title: "Empty Basemap",     thumbnailUrl: "url/of/empty/image" }); basemapGallery.add(emptyBasemap); ...

I guess what you did is to create an empty basemap, and add it to the basemap gallery. Am I right? Please refer to the ESRI document. All basemaps added to the gallery need to have the same spatial reference. If the default ArcGIS.com basemaps are used then all additional items added to the gallery need to be in Web Mercator (wkids: 102100, 102113 and 3857). If the default basemaps are not used you can add basemaps in any spatial reference as long as all the items added to the gallery share that spatial reference. To achieve the best performance, it is recommended that all basemaps added to the gallery are cached (tiled) layers. Have you tried to create a blank map document with the spatial reference set to webMercator, and then publish it as a map service? In the code, Create a basemapLayer with the service just published. Create a basemap fed in the basemapLayer. Add basemap to the basemap gallery. ... View more

ok...one last try. Replace all your JS code with the below one with two assumptions: The basemaplayer spatial reference is the same as the map, 2953. The point coordinates in strPoints are lat/lon. var strPoints; // add code to populate strPoints here. require([ "esri/map", "esri/geometry/Extent",     "esri/geometry/Point",     "esri/symbols/SimpleMarkerSymbol",     "esri/graphic",     "esri/tasks/GeometryService",     "dojo/_base/array",     "dojo/_base/lang",     "dojo/_base/Color",     "esri/layers/ArcGISDynamicMapServiceLayer",     "dojo/domReady!" ], function (Map, Extent, Point, SimpleMarkerSymbol, Graphic, GeometryService, arrayUtiles, lang,         Color, ArcGISDynamicMapServiceLayer) { var initialExtent = new Extent({   "xmin": 2306896.79,      "ymin": 7278537,      "xmax": 2710915.5,      "ymax": 7674860.5,      "spatialReference": {       "wkid": 2953   } }); //102100, 2953 var map = new Map("NBmap", {   extent: initialExtent }); var basemaplayer = new ArcGISDynamicMapServiceLayer("http://swv25orat01.gnb.ca:6080/arcgis/rest/services/WFRS/WFRS_FireSummarymxd/MapServer"); map.addLayer(basemaplayer); map.on("load", function() {   map.disablePan();   map.disableScrollWheelZoom();   map.hideZoomSlider();   var geometryService = new GeometryService("http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer");   var arrycoord = strPoints.split(",");   var x, y, point;   var symbol = new SimpleMarkerSymbol(     SimpleMarkerSymbol.STYLE_CIRCLE,                 16,                 null,                 new Color("#ce641d")   );   for (i = 0; i < arrycoord.length; i = i + 2) {    x = arrycoord;       y = arrycoord[i + 1];       point = new Point(x, y);       geometryService.project(point, map.spatialReference, function (newpoint) {        var graphic = new Graphic(newpoint, symbol);           map.graphics.add(graphic);       });   }; }); }); ...

Can you post your updated app and the data in strPoints? Must be some simple thing we missed. ... View more

I forgot to create the graphic before adding to the map. Ok, try one of these two again. var x, y, point, graphic; var symbol = createSymbol("#ce641d"); var srLatLon = new SpatialReference({ wkid: 4326 }); for (i = 0; i < arrycoord.length; i = i + 2) {     x = arrycoord;     y = arrycoord[i + 1];     point = new Point(x, y, srLatLon);     graphic = new Graphic(point, symbol);     map.graphics.add(graphic); }; Or, var x, y, point, graphic; var symbol = createSymbol("#ce641d"); var srLatLon = new SpatialReference({ wkid: 4326 }); for (i = 0; i < arrycoord.length; i = i + 2) {     x = arrycoord;     y = arrycoord[i + 1];     point = new Point(x, y, srLatLon);     geometryService.project(point, map.spatialReference, function (newPoint) {         var graphic = new Graphic(newPoint, symbol);         map.graphics.add(graphic);     }); }; Also change createSymbol function as: function createSymbol(color) {     return new esri.symbol.SimpleMarkerSymbol( esri.symbol.SimpleMarkerSymbol.STYLE_CIRCLE,    // change to the style you like 16,    // change to the size you like         null, new dojo.Color(color)     ); }; ...
