I have an offline Gdb that I use and I have noticed that random segments of my roadcenterlines will not display when I pan to them. However, when I pinch the device screen, those segments appear, but I pan away and come back and they are invisible again. I also noticed that labels for roads, again random, do not display. Nothing I do makes this change. My Spatial Reference is matching with the MapView and my FeatureLayer. I have attached an image, if you can see it, where there is a broken segment on the road running NW from the intersection. Once again, if I pinch the screen it will appear. If I pan away and back to it, it disappears. ... View more

I am attempting to execute a simple query of a rest service containing a point feature class. When I build out the query I am receiving no errors. When I run the application in a browser I receive error 400: invalid or missing parameters.

I have writers block on this one - so deep I cannot even provide any code to start with. I have a feature class that contains fields for: UNITS:  Emmergency Service Vehicles YEAR:    Year of a call the unit went on (4 years are covered) In this feature class there are multiple calls for each unit during each of the years. I have been asked to create a map which a user can select a unit, or multiple units, with a checkbox, and then in a different layer list select the year they wish to view, or multiple years. Example: I have UNIT A, UNIT B and UNIT C turned on (checked) in one list, I then turn on (check) 2010 and 2011 in another list and points populate the map that those units went on during those years. I have the feeling this might be a basic solution, but I cannot find an example. I am still a novice at Silverlight so this is not coming easy. Any recommendations would be extremely appreciated.

Hey All I have looked through quite a few of the posts on this process. I am using the find a feature on a map sample, modified slightly. When I click on a row in the datagrid I need the previous point, or polyline to go away. Right now I have a secondary symbol set up to show the selected street in black, when I click on the next street I need that previous selection to disappear. In the datagrid under the STREET tab, if there is a streetname with no address to its left - then that is an actual polyline from a street centerlines feature class. Click on one of those and you will see the zoom and the symbol change for the selected road. // JavaScript Document// JavaScript Document dojo.require("dojox.grid.DataGrid"); dojo.require("dojo.data.ItemFileReadStore"); dojo.require("esri.map"); dojo.require("esri.tasks.find"); dojo.require("dijit.layout.AccordionContainer"); dojo.require("dijit.layout.BorderContainer"); dojo.require("dijit.layout.ContentPane"); dojo.require("dijit.form.Button");       var findTask, findParams;       var map, center, zoom;       var grid, store; function init() {   dojo.connect(grid, "onRowClick", onRowClickHandler);         center = [-77.985, 39.450];         zoom = 11;         map = new esri.Map("map", {           basemap: "hybrid",           center: center,           zoom: zoom,      minZoom: 11,      maxZoom: 19,      logo: false,      sliderStyle: 'small'         });         //Create Find Task using the URL of the map service to search         findTask = new esri.tasks.FindTask("http://maps.berkeleywv.org/arcgis/rest/services/research_911/Operational/MapServer/");         dojo.connect(map, "onLoad", function() {           //Create the find parameters           findParams = new esri.tasks.FindParameters();           findParams.returnGeometry = true;           findParams.layerIds = [0,1,9];           findParams.searchFields = ["FULLADDR","FULLNAME","INTERSECTION"];           findParams.outSpatialReference = map.spatialReference;           console.log("find sr: ", findParams.outSpatialReference);         });       }       function doFind() {         //Set the search text to the value in the box         findParams.searchText = dojo.byId("ownerName").value;         findTask.execute(findParams,showResults);       }       function showResults(results) {         //This function works with an array of FindResult that the task returns         map.graphics.clear();         var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([98,194,204]), 2), new dojo.Color([98,194,204,0.5]));     var markerSymbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 10, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 0, 0]), 1), new dojo.Color([255, 119, 25, 9]));     var intersectionmarkerSymbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_DIAMOND, 10, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 255, 255]), 2), new dojo.Color([0, 0, 0, 8]));         //create array of attributes         var items = dojo.map(results,function(result){           var graphic = result.feature;           //graphic.setSymbol(symbol);      switch (graphic.geometry.type) {       case "polygon":       graphic.setSymbol(symbol);       break;       case "point":                   graphic.setSymbol(markerSymbol);                   break;                 case "polyline":                   graphic.setSymbol(lineSymbol);                  break;       case "multipoint":       graphic.setSymbol(intersectionmarkerSymbol);       break;      }           map.graphics.add(graphic);           return result.feature.attributes;         });                 //Create data object to be used in store         var data = {           identifier: "OBJECTID",  //This field needs to have unique values           label: "OBJECTID", //Name field for display.

I have looked through numerous postos on this, but I cannot seem to solve my problem. The attributes are not populating my datagrid. If I use BJECTID or my GlobalID for the features the datagrid populates with that information, but no other attributes. The ZOOM to feature even works. Any assistance would br greatly appreciated Thank you. <!DOCTYPE html> <html>   <head>     <meta http-equiv="Content-Type" content="text/html; charset=utf-8">     <meta http-equiv="X-UA-Compatible" content="IE=7, IE=9">     <!--The viewport meta tag is used to improve the presentation and behavior of the samples       on iOS devices-->     <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">     <title>911 Research</title>     <link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.3/js/dojo/dijit/themes/claro/claro.css">     <link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.3/js/dojo/dojox/grid/resources/Grid.css">     <link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.3/js/dojo/dojox/grid/resources/claroGrid.css">     <link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.3/js/esri/css/esri.css">     <script type="text/javascript">   dojoConfig = {     parseOnLoad: true   }; </script> <script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=3.2"></script> <script type="text/javascript" language="Javascript">   dojo.require("dojox.grid.DataGrid");   dojo.require("dojo.data.ItemFileReadStore");   dojo.require("esri.map");   dojo.require("esri.tasks.find");   dojo.require("dijit.layout.BorderContainer");   dojo.require("dijit.layout.ContentPane");   var findTask, findParams;       var map, startExtent;       var grid, store;   function init() {    dojo.connect(grid, "onRowClick", onRowClickHandler);     var startExtent = new esri.geometry.Extent({"xmin":2328173.3028935865,             "ymin":282104.61435875297,             "xmax":2441858.2039148845,             "ymax":411949.6673321724,             "spatialReference":{"wkid":102750}});     map = new esri.Map("map",{extent:startExtent, maxZoom: 1, minZoom: 7, sliderStyle: "large"});     var countyLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://maps.berkeleywv.org/arcgis/rest/services/Berkeley_Boundary/MapServer", {     });     map.addLayer(countyLayer); var roadsLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://maps.berkeleywv.org/arcgis/rest/services/Roads/MapServer"); map.addLayer(roadsLayer); var structuresLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://maps.berkeleywv.org/arcgis/rest/services/berkeley_structures/MapServer"); map.addLayer(structuresLayer);     //create find task with url to map service     findTask = new esri.tasks.FindTask("http://maps.berkeleywv.org/arcgis/rest/services/Berkeley_Addresses/MapServer");     //Create the find parameters         findParams = new esri.tasks.FindParameters();         findParams.returnGeometry = true;         findParams.layerIds = [0];         findParams.searchFields = ["FULLADDR"];       }       function doFind() {         //Set the search text to the value in the box         findParams.searchText = dojo.byId("searchText").value;         findTask.execute(findParams,showResults);       }       function showResults(results) {         //This function works with an array of FindResult that the task returns         map.graphics.clear();         var symbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_DIAMOND, 10,           new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID,             new dojo.Color([0, 0, 0]), 1),             new dojo.Color([255, 255, 0, 1]));         //Create items array to be added to store's data         var items = []; //all items to be stored in data store         for (var i = 0, il = results.length; i < il; i++) {             items.push(results.feature.attributes);  //append each attribute list as item in store             var graphic = results.feature;             //variable for the point extent             var pt = graphic.geometry;             graphic.setSymbol(symbol);             map.graphics.add(graphic);         }         //Create data object to be used in store         var data = {           identifier: "GlobalID",  //This field needs to have unique values           label: "GlobalID", //Name field for display.

I am trying to create a SEARCH where the user types in a road name, and the display box shows all addresses that fall under that road name. The user can then select the address they want and the map will auot zoom to that point. I have seen some posts close to this, but not quite what I need. Can anyone get me started in the right direction? Thank You ... View more
