    <p>When I create map object using ArcGISDynamicMapServiceLayer then things work fine but since I need lot of graphics and want to handle user interactions on map so I want to feature layer to my map but when I add feature layer the browser hangs.</p> <p>Please let me know what could be the issue how can I avoid feature layer from hanging from my machine. Can I add onclick mouse over functionality for ArcGISDynamicMapServiceLayer Below is the code </p> <pre><code>map = new esri.Map("map"); var layer = new esri.layers.ArcGISDynamicMapServiceLayer("http://10.32.9.106:6080/arcgis/rest/services/Administrative_Maps/World_Countries_v1/MapServer"); map.addLayer(layer); var url = "http://10.32.9.106:6080/arcgis/rest/services/Administrative_Maps/World_Countries_v1/MapServer/0"; var info_content = "&lt;table&gt;&lt;tr&gt;&lt;td&gt;&lt;b&gt;COUNTRY :&lt;/b&gt;&lt;/td&gt;&lt;td style='text-align:right'&gt;${COUNTRY}&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;"; var infoTemplate1 = new esri.InfoTemplate("${COUNTRY}", info_content); var fl = new esri.layers.FeatureLayer(url, { id: "world-regions", infoTemplate: infoTemplate1 }); map.addLayer(fl); </code></pre> <p>MY HTML CODE Is below</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt; &lt;meta http-equiv="X-UA-Compatible" content="IE=7, IE=9, IE=10"&gt; &lt;meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"&gt; &lt;title&gt;Feature Layer Only Map&lt;/title&gt; &lt;link rel="stylesheet" href="http://js.arcgis.com/3.6/js/esri/css/esri.css"&gt; &lt;style&gt; html, body, #map { height: 100%; width: 100%; margin: 0; padding: 0; } &lt;/style&gt; &lt;script src="http://js.arcgis.com/3.6/"&gt;&lt;/script&gt; &lt;script&gt; dojo.require("esri.map"); dojo.require("esri.layers.FeatureLayer"); dojo.require("esri.tasks.QueryTask"); var map; function init(){ try{ map = new esri.Map("map"); var layer = new esri.layers.ArcGISDynamicMapServiceLayer("http://10.32.9.106:6080/arcgis/rest/services/Administrative_Maps/World_Countries_v1/MapServer"); map.addLayer(layer); var url = "http://10.32.9.106:6080/arcgis/rest/services/Administrative_Maps/World_Countries_v1/MapServer/0"; var info_content = "&lt;table&gt;&lt;tr&gt;&lt;td&gt;&lt;b&gt;COUNTRY :&lt;/b&gt;&lt;/td&gt;&lt;td style='text-align:right'&gt;${COUNTRY}&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;"; var infoTemplate1 = new esri.InfoTemplate("${COUNTRY}", info_content); var fl = new esri.layers.FeatureLayer(url, { id: "world-regions", mode: esri.layers.FeatureLayer.MODE_ONDEMAND, autoGeneralize :true, allowGeometryUpdates:false, infoTemplate: infoTemplate1, outFields: ["COUNTRY"] }); dojo.connect(fl, "onLoad", function(){ console.log(" adding feature layer"); fl.setAutoGeneralize(true) map.addLayer(fl); console.log("allowGeometryUpdates "+fl.allowGeometryUpdates); console.log("editable "+fl.isEditable()); console.log("autoGeneralize"+fl.autoGeneralize); console.log("geometryType"+fl.geometryType); console.log("graphics"+fl.graphics); console.log("defaultVisibility "+fl.hasAttachments); }); var queryTask = new esri.tasks.QueryTask(url); //build query filter var query = new esri.tasks.Query(); query.returnGeometry = true; query.where = "COUNTRY='India'"; infoTemplate = new esri.InfoTemplate("Alert", "Alert for Re-insurance"); dojo.connect(queryTask, "onComplete", function(featureSet) { alert('calling queryTask'+featureSet); //map.graphics.clear(); try{ /*var sfs = new SimpleFillSymbol(SimpleFillSymbol.STYLE_FORWARD_DIAGONAL, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.5])); alert('somethign');*/ var symbol0 = new esri.symbol.SimpleFillSymbol().setColor(new dojo.Color([255, 0, 0, 0.9])); //QueryTask returns a featureSet.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
