Did you in the end found a solution? I would be very interested to see it since i'm running into the same problem Hi Derek I am experiencing the same problem with my graphic layer on the print pdf map. When graphics added to the map, the print widget doesn't work, when I clear the graphic layer, the print widgets works printing all the other dynamic layer legends. The error I get from Json response, when I add the graphic layer to map is {"error":{"code":400, "message":"unable to complete operation.", "details":["Error exectuing tool.: Layer\"_exploreKentGraphicsLayerId\": Unsupported 'type' in symbol: esriCLS.\nLayer\"_exploreKentGraphicsLayerId\nFailed to execute (Export Web Map Task). Can you please let me know, how to resolve this. Regards Ganesh ... View more

Ganesh, What you are looking for is snapping. SnappingManager provides exact the same as you described. https://developers.arcgis.com/javascript/jsapi/snappingmanager-amd.html#getsnappingpoint HI Guys I found the answer finding all the points in a polyline and getting their distance and here is the code below. If anyone need this, can you use them to suit their needs. // ******************************************************************** // Gets the distance from user's location for my nearest feature types. // // Parameters: // ----------- // featureGeometryType - the type of feature. // feature - the feature itself. // location - the location parameter for my nearest service. // ******************************************************************** function GetDistance(featureGeometryType, feature, location) {     try     {         var x = GetXFromLocationParameter(location);         var y = GetYFromLocationParameter(location);         var startPoint = new esri.geometry.Point(x, y, _map.spatialReference);     //    alert(startPoint.x + "," + startPoint.y);         var endPoint;         switch (featureGeometryType)         {             case "esriGeometryPoint":                 endPoint = new esri.geometry.Point(feature.geometry.x, feature.geometry.y, _map.spatialReference);

Hi Derek, Thank you very much for looking at this thread and providing the clue to figure out. However, I figured out the answer to find the nearest point of a polyline by looping all the polyline linesegment  or paths. I will post my working code tomorrow, so that it will help someone to use the code. Once again, thanks for your help. We don't have a method that returns all points from a polyline. You'll have to loop through polyline.paths and look at points from there. ... View more

HI Guys, In continuation of the above thread, I have a sample which was done using Microsoft Bing maps, where the user could get all the points of the line using poly.getLocations() method. Is there similar method in arcgis javascript api.

Hi James Thank you once again for your support. I have created my AGOL account and logged on to your application to see how it works. It was really good. If I want to use the Spatial analysis service within AGOL where should I look within account to create an application similar to the one you created. Not sure exactly where to look for the spatial anlaysis service within AGOL?  Any help would be much helpful. Regards Ganesh ... View more

Hi Guys I have solved geoprocessing problem i have with my model. Actually, When I publish the model alone as a geprocessing service, it reports that the near layer data are not found. When I include the model in the Arcmap mxd document and published them as a geoprocessing service with result map service, the model tries to work and it could get the results for my near features in the rest end point. To be honest, I really don't know why the model works when it is published as a geoprocessing with result map service and why it doesn't work when it is published just a model and basically, it is mystery. Now, my next step is to integrate my geoprocessing result map service into web application to see how it works. I have to write my javascript code and it is a real challenge here to see how it works. Regards Ganesh Hi Guys, I have built my Geoprocessing model to find nearest feature from the input location in model builder and published them as a geoprocessing service. The model works perfectly well in ARCGIS desktop. when I published them as a geoprocessing service, and tested the service with REST end points in arcgis server using submit Job Operation, I got the following error. Basically, the error reports that NearFeature layers doesn't exist, but in reality it does exist in the map and it has hard coded and the second issue is the output datasets -from the geoprocessing service reports that the data already exist. Actually, I have checked the Overwrite Outputs of geoprocessing operations in Arccatalog and ArcMap before building the model. The model overwrites output datasets and finds all near feature layers when it is run from Arcmap. However, when it is run from REST end points, it causes errors saying data already exist or not found. Have anyone come across this issue when publishing them as a geoprocessing service. Anyhelp would be much appreciated.

HI James Once agian, thank you very much for the code and working sample. Unfortunately, when I tried to play with your application, it didn't allow me, as it require AGOL account to log on to view the result.

Hi James Thank you very much for your code. Can you provide some working sample code, at the moment, I can't see how it works. If you can provide this, that would be really good.

Hi James Could please post your sample codes in JS fiddle for the find nearest functionality? At the moment, I can't find any sample codes in the ESRI javascript api for find nearest features. https://developers.arcgis.com/rest/a...nd-nearest.htm Do we need to have  an AGOL account to use this service? or is this any free developer account to this service. At the moment, I am developing my own geoprocessing service using model builder to create my own custom service to integrate into my application. http://forums.arcgis.com/threads/103522-NearAnalysis-Geoprocessing-Service-arcgis-javascript-api Please read above thread, I will post some model builder sample later this week. thanks ganesh ...

Ganesh, Thanks for letting us know. I was able to reproduce the fact that the delete button and delete listener aren't working on Chrome in the Attribute Inspector sample. I can see that saves are working by using the browser console. Are you able to see the saves occurring in the background? Have you opened a support ticket yet? That way we can get this tracked and in the queue. If you need a quick fix you can always manually build your own custom delete button and set the default delete button to false. Here is a psuedo-code example to get you pointed in the right direction:           var layerInfos = [{ 'featureLayer': petroFieldsFL, 'showAttachments': false, 'showDeleteButton': false, /* set this to false */                   .... var dButton = new Button({ label: "Delete", "class": "dButton"}); domConstruct.place(dButton.domNode, attInspector.deleteBtn.domNode, "after"); dButton.on("click",function(evt){     updateFeature.getLayer().applyEdits(null,null,[updateFeature]);     map.infoWindow.hide(); }) https://developers.arcgis.com/javascript/jsapi/attributeinspector.html#event-delete -Andy Hi Andy thank you very much for your quick turnaround. I am really amazed to see that you have responded to my query. The only problem is with the delete button and the save button works perfectly alright. I haven't logged a ticket with ESRI and to be honest, I don't how to log a support ticket with ESRI. Please guide on this. Finally, I will try to create a custom delete button as per your advice and see whether that one works and finally, a big thank you for the custom code as well. Regards Ganesh ... View more

Ganesh, you're right. I misunderstood your requirements. When you said that you want to use any kind of feature, I've thought about using the polygon centroids (in case of polygons) and the line middle points. If you need the closest vertices, this solution won't work. I don't know the how the arctoolbox tool that you talk works, so I think that I can't help here. HI GIS folks, Can you anyone give me a clue on this or point me the right sample application to work on. Regards Ganesh ... View more

Hi Kevin, Attached is an example on how to do this.  The application searches for a park by it's name.  What I did was added the below code to a new JavaScript file called 'find.js': require([   "esri/map",   "esri/tasks/QueryTask",   "esri/tasks/query",   "esri/geometry/Extent",   "esri/SpatialReference",   "esri/InfoTemplate",     "esri/graphic",   "esri/symbols/SimpleFillSymbol",   "esri/symbols/SimpleLineSymbol",     "dojo/parser",   "dojo/dom",   "dojo/on",    "dojo/ready"],     function(     Map, QueryTask, Query, Extent, SpatialReference, InfoTemplate,     Graphic, SimpleFillSymbol, SimpleLineSymbol,     parser, dom, on, ready   ){     ready(function() {         var button = dojo.byId("typeButton")       on(button, "click", findPark)       function findPark(){           map.graphics.clear();           var queryTask = new QueryTask("http://services.arcgis.com/Fz6BBJUji5ArUSDM/arcgis/rest/services/Parks/FeatureServer/0");               var query = new Query();                     query.returnGeometry = true;           query.outFields = ["*"];            query.outSpatialReference = {"wkid":102100};           query.where = "NAME = '" + dojo.byId("txtBox").value + "'";              queryTask.execute(query);           queryTask.on("complete", selectResults)       }             function selectResults(graphics){                   var parkName = graphics.featureSet.features[0].attributes["NAME"];                         var park = new Graphic(graphics.featureSet.features[0].geometry);                   var infoTemplate = new InfoTemplate("PARK:", parkName);                      park.setInfoTemplate(infoTemplate);                                            map.graphics.add(park);         var extent = new Extent(map.graphics.graphics[0].geometry._extent.xmin, map.graphics.graphics[0].geometry._extent.ymin, map.graphics.graphics[0].geometry._extent.xmax, map.graphics.graphics[0].geometry._extent.ymax, new SpatialReference({ wkid:102100 }));                         map.setExtent(extent, true);                 featureArray = [];         featureArray.push(park);                        var templatePt = park.geometry.getCentroid();         map.infoWindow.setFeatures(featureArray);         map.infoWindow.show(templatePt);                         }       })   }); Next, I updated the index.html to call the new javascript file: <script type="text/javascript" src="javascript/find.js"> And to create the text box and button: <div id="webmap-toolbar-left">                 <input type="text" id="txtBox">                 <input type="button" id="typeButton" value="Find Park"> </div> You can search for park, i.e. 'Fairmount Park', and the app will select, zoom to the park, and display a pop-up. Hi jskinner Really nice functionality. Thank you for this. Actually, I need some help from you. Basically I am trying to find nearest features from an input location. The near feature location would be point, line and polygon and I need to query 5 nearest features and if the nearest feature is a line or polygon then it should find the nearest vertices from the line or polygon rather than using the centroid to calculate their distance. Can you point me to the sample code please.  Regards Ganesh ... View more
