Hi Dawn If by actual points you mean feature class, it is probably correct that they perform better in ArcMap. But I wouldn't convert an XY table into a feature class, unless performance is really tanking. I doubt that you will notice the difference in a map service.  But you can always test. Create a feature class from the XY table in the SDE, add it to a map document. Then add the XY table to that document and create and XY event layer. Publish the service and test the performance. Have a great day! Darina ... View more

Hi Dawn, I am not sure what your GIS architecture and workflows are but if you can feed the map service directly from the SDE, then you should that. The ArcGIS software is optimized to work well with SDE databases, and there is no performance issue there. If you data is stored as a feature class in SDE and you are allowed to connect to it, then that is your best option. Use that feature class in your map document to publish to ArcGIS server. Even if it is just a table with XYs, use it from SDE.  I haven't tested the impact of re-projecting on the fly to Web Mercator, so I can't comment on that. I am personally not a fan of having multiple copies of data in different places, and try to avoid it when possible.  If you are not allowed to use the data from SDE in a map service, then you can definitely use it from another non-SDE database as an XY event table. In this case, since you already will be manipulating the data and copying it to another place, I would calculate the XYs in state plane and in Web Mercator to avoid re-projecting on the fly. Then in the map document (.mxd) for the map service, I would use the instructions in my answer above to connect to the non-SDE database and will display the XY table by using the web mercator XYs and setting the web mercator as the coordinate system of the event layer.  Hope that helps you a little!  Darina ...

Hi Jenna, After looking at the code, I found a way for  you to do what you need to do with very little change. Disclaimers: !!! Be advised though, it is a total hack and I have not tested all the functionality to see if it breaks anything else. !!! I suggest, you create an issue on Github for your problem, and hopefully someone will look into it, and fix it. !!! Best scenario for you would be to create and cache a hybrid service (image with road names), which is recommended in the application documentation. !!! If you have no control over that, then you can try my hack, but make very good notes, so when you are upgrading the application, and it breaks, you know where to look. Here it is: 1. Order your layers this way (I am using the fact that the first layer is added on the map and always stays there, so we need this to be the imagery. Then the second layer should be the one you need displayed on the map initially, and that usually is just a street map): // Set baseMap layers         BaseMapLayers: [     {             Key: "imagery",             ThumbnailSource: "js/library/themes/images/imagery.png",             Name: "Imagery",             MapURL: "http://yourserver/arcgis/rest/services/Imagery/MapServer"         },     {             Key: "streetMap",             ThumbnailSource: "js/library/themes/images/parcelmap.png",             Name: "Streets",             MapURL: "http://yourserver/arcgis/rest/services/GeneralPurpose/MapServer"         },     {             Key: "imageryStreetNames",             ThumbnailSource: "js/library/themes/images/imagery.png", //change image to some hybrid image             Name: "Imagery",             MapURL: "http://yourserver/arcgis/rest/services/StreetNames/MapServer"         },     {             Key: "topoMap",             ThumbnailSource: "js/library/themes/images/imagery.png",             Name: "Topographic",             MapURL: "http://services.arcgisonline.com/arcgis/rest/services/World_Topo_Map/MapServer"     }], 2. Change "0" to "1" in on the commented line in baseMapsGallery.js. In this way, the imagery which was added first will be there but hidden behind the street map, which has and index of 1 instead of 0. So change the "0" to "1" to have your street map popup first: postCreate: function () {             var i, basemapContainer, layer,                 baseMapURL = 0,                 baseMapURLCount = 0,                 baseMapLayers = dojo.configData.BaseMapLayers;             for (i = 0; i < baseMapLayers.length; i++) {                 if (baseMapLayers.MapURL) {                     this.map.addLayer(this._createBaseMapLayer(baseMapLayers.MapURL, baseMapLayers.Key));                 }                                 if (baseMapURLCount === 1) { //on this line change "0" to "1" as shown here                     baseMapURL = i;                 }                 baseMapURLCount++;             }             basemapContainer = domConstruct.create("div", {}, dom.byId("esriCTParentDivContainer"));             basemapContainer.appendChild(this.esriCTDivLayerContainer);             this.layerList.appendChild(this._createBaseMapElement(baseMapURL, baseMapURLCount));             if (baseMapURLCount >= 1) {                 layer = this.map.getLayer(baseMapLayers[baseMapURL].Key);                 layer.show();             }         }, Test it. Hope it works for you, if nothing else is possible. Darina ... View more

Jenna, I am not familiar with this application, but after brief look at it, I don't think that you can configure it to have two layers in your basemap without making any code changes. I downloaded it now, and will try it. I will let you know if I come up with a solution. Darina ... View more

Part of what application is this configuration file? ... View more

Jenna, Here is a sample code of how to add roads on top of the imagery: var map = new Map("map", {                 basemap: new Basemap({                     layers: [                         new BasemapLayer({ url: 'http://myserver/arcgis/rest/services/Maps/Aerials/MapServer' }),                         new BasemapLayer({ url: 'http://myserver/arcgis/rest/services/Maps/StreetNames/MapServer' })                     ]                 })             }); Best regards, Darina ...

Hi Frieda, Thank you for your reply. Yes, that is what I observe, results come back but nothing happens if autoSelect is false. My code is attached. (I just copied one of the ESRI samples, and plugged in my services, and added event listeners for debugging). I am also attaching an image of the console showing 5 suggestion coming back and 27 results coming back, but no results list. ... View more

Frieda and Robert, I just started playing with the Search widget, and I am also having trouble with the result list. 1). I don't get a results list no matter what settings I have for "autoSelect". And I don't ever see the results list or the "Show more results" option. I am not sure what the problem is, as i can see by debugging that I have 27 results back. 2). Also, for some reason I only get 5 suggestion back. I tested this in the services directory, and I only get 5 back there. Again, not sure why (created a ticket for this problem, but haven't been contacted yet). Frieda, Even if your Feature Layers comes from a 10.3 service, suggestion will not work if your underlying database does not support pagination. Show stopper. I did find a workaround, but it gets complicated working with polygon and line layers. I created address locators ("Single Field") from the layer of interest, enabled suggestion on the locator, and then enabled suggestion on the geocoding service. The suggestions work, but the returned geometry is a point. If anybody has more experience with the Search widget, and knows how to fix 1) and 2), please, share your knowledge. Thank you! ...

Hi guys, I was wondering if any of you have found a way to prevent the Search widget from automatically performing a search when a suggested value is selected? Not having a database supporting pagination is messing me up, and I have to create locators from my layers to use the suggestion functionality, but I need to perform the search on the feature layers and actually return polygons instead of the point that locators return. I see that I can hop in after the search is performed and results are returned, and do what I need to do, but that's kind of chatty. Thank you! ... View more

Mike, I don't see any other references in the code to my server. But i think I found the problem. I had an empty module in the define section of the start.js. I had the areaExtent added, but I had not put any code in there, and I haven't used it in the code. But I guess, it was messing IE. After I removed it from the list, the search.htm and index.htm started working as expected (both pages are using start.js). define(     [         "dojo/_base/array",         "dijit/registry",         "dijit/form/Button",         "dijit/form/RadioButton",         "modules/areaExtent"            ],     function (arrayUtil, registry, Button, RadioButton, AreaExtent) When I was packing the code to attach it here I noticed it, and removed it from the file, so it is not in the attachment, and the attached code works fine in IE. Thanks to you trying to make it work, I had to install the code that I packed and test it. This is when I noticed that this code works, but not the one I originally had. I started looking for the differences, and found it. Thank you! Darina ... View more

Mike, I just copied the files that I attached to a web server (IIS 7), made the changes I told you, and for search.htm I get a bunch of buttons on the left, map in the center, and legend on right. With index.htm, I get just some radio buttons and buttons, that do nothing for now. Both work fine in Firefox, Chrome, and sometimes in IE8. I am not sure why you don't get the map. Darina ...

Mike, Map services are defined only in the search.htm: [HTML] <script type="text/javascript">         require(["modules/start", "modules/app", "modules/search"],             function (start, mapApp) {                                start.init("search");                 mapApp.init({                     basemapUrl: "http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer",                     zipcodesUrl: "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/3",                     mapContainerId: "map",                     legendContainerId: "legend"                 });             });     </script> [/HTML] And one more thing. I was running this in Visual Studio web server, so the paths parameter in the dojoConfig was working. On a web server, please change the paths parameter in the dojoConfig with: paths: { modules: location.pathname.replace(/\/[^/]+$/, "") +  "/js/modules" } The index.htm uses no arcgis classes, but has the same caching problem: buttons don't get created in IE. So, I think, this more of a Dojo problem. Thank  you! Darina ... View more

Mike, Thank you for looking into it. The services are not public. And I just substituted the server name with "myserver". Try using the ESRI services. I get the same behavior with them too.  Tiled layer (basemap): http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer Feature Layer (zipcodes): http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/3 The map will draw slow though with these services, because my code does not filter the feature layer.
