Assume you are using AMD style. Make sure to include "esri/graphicsUtils" to the dependency list, and take graphicsUtils as the alias. var resultExtent = graphicsUtils.graphicsExtent(results.features); map.setExtent(resultExtent); ... View more

Change: for (var i = 0, il = results.features.length; i < il; i++) {                 var graphic = results.features;                 graphic.setSymbol(symbol);                 map.graphics.add(graphic);                 map.centerAndZoom(results.features.geometry, 0.1);                                 alert(results.features.length); //this returns 1 } To: var graphic; for (var i = 0, il = results.features.length; i < il; i++) {       graphic = results.features;       graphic.setSymbol(symbol);       map.graphics.add(graphic); } map.setExtent(esri.graphicsExtent(results.features)); ...

Hi Hank, Can you get the results back from the query? The reason why I am asking is that you set query.geometry = evt.mapPolygon; which I believe should be query.geometry = evt.mapPoint; In addition, I don't know why you construct the infoTemplate that way. The first parameter to new InfoTemplate should be for the title, like new InfoTemplate(title,content). The first parameter set in your code seems to be the content you like to display in the popup. Am I right? ... View more

The feature limit does not apply to featureLayer.queryIds. Here is the description of the method on ESRI API description. Query for ObjectIds. There is no limit on the number of ObjectIds that are returned from the server. But I believe the feature limit does apply to setDefinitionExpression. ... View more

Actually, all these values are considered falsy in javascript: null, undefined, false, "", 0. So instead of using if statement to evaluate for each case, just use the value itself should suffice to evaluate it's true value or falsy value. We do need to consider the case where " " is true, but "" is falsy. So using dojo.trim would be needed in some cases. Here is a blog to explain that. ... View more

maxRecordCount is a read-only property which is carried over from the map service. The only way you can increase the limit is to change maxRecordCount of a map service using ArcGIS Server Manager or ArcCatalog. Once set and published, maxRecordCount cannot be changed. In addition, maxRecordCount can only be set at the map service level, not the feature layer level. I've had a hard time to find it out. To ESRI development team: it's truely beneficial to be able to change maxRecordCount at both map service and feature layer level via JSAPI. One scenario we have experienced is that our app has to support both IE8 and other modern browsers. Since IE8 is much slower in Javascript execution, we have the need to limit maxRecordCount to 500 for IE8 users, and keep 1000 or even 2000 for other users. ... View more

If the feature layer, pointdata, is created correctly, the below code sample should meet your need. pointdata.on("click", function(evt) {     var hashId = evt.graphic.attributes["hash_id"]; }); In addition, based on the ESRI API description, the structure of the feature collection should be { layerDefinition: {           geometryType": "esriGeometryPoint",           objectIdField": "ObjectID",           drawingInfo": {           },           "fields": [{             "name": "ObjectID",             "alias": "ObjectID",             "type": "esriFieldTypeOID"           }, ...]    },    featureSet: {      features: [],      geometryType: "esriGeometryPoint"    } }; Here is a sample of creating a feature layer from a feature collection. ...

The issue is because the map is in navigation mode by default, so when you press down the mouse key, the map responds with PAN operation. What you can do is to disable the map navigation when the user long presses the feature of a feature layer, and enable it once you finish handling the event. In addition, I would define the onMouseDown event handler against the feature layer instead of the map. Here is the code sample assuming the featureLayer created somewhere else.     var timer, isPan = this.map.isPan;     on(this.featureLayer, "mouse-down", lang.hitch(this, function(e) {         timer = setTimeout(lang.hitch(this, function() {             isPan && this.map.disablePan();             this.selectFeatures(e.screenPoint).then(lang.hitch(this.editor, this.editor.moveFeature));         }), 5*1000);     }));     on(this.featureLayer, "mouse-up", function(e) {         clearTimeout(timer);         isPan && this.map.enablePan();     }); ...
