Jim,   If possible, please check the values in this field at the REST service endpoint to verify that the field values are returned by the service as an integer value that represents the number of milliseconds since midnight Jan 1, 1970 in UTC.  Looking at the json response of the query is what I would suggest.   So, if you can create a valid Date instance from the string returned by the HTML5 widget (that truly represents the date and time you want to query with) then I would suggest you use the ".valueOf()" method on the Date instance to get the value in UTC milliseconds and use it in your query.  For example: query.push( "time > " + (new Date(startDate)).valueOf() ); More info on Date objects: JavaScript Date Object If this does not work, then it would help if we had a public map service endpoint that your query is trying to access so we can figure out how to properly do this date query. ...

Editing a specific geodatabase version is supported in the JS API.  For example, you can use the FeatureLayer.setGDBVersion(...) to target a specific geodatabase version. ... View more

Here's another attempt at a jsfiddle that should work: http://jsfiddle.net/99vD9/5/ var elevationServiceUrl = "http://sampleserver4.arcgisonline.com/ArcGIS/rest/services/Elevation/ESRI_Elevation_World/MapServer/exts/ElevationsSOE/ElevationLayers/1/GetElevationAtLonLat"     dojo.connect(map, 'onClick', function (evt) {         esri.request({             url: elevationServiceUrl,             content: {                 lon: evt.mapPoint.getLongitude(),                 lat: evt.mapPoint.getLatitude(),                 f: "json"             },             callbackParamName: "callback",         }).then(function (response, io) {             alert("Elevation = " + response.elevation.toFixed(1) + " meters");         }, function (error, io) {             console.error("Unable to get elevation", error);             alert("Unable to get elevation...");         });     }); ...

What I've done in the past is to assign a value of 200px to the min-height and min-width properties to the map div via css.  I believe this ensured that the map div sizes are not set to zero by external widgets when they are hidden. ... View more

Jon is correct, you need to wait until after the map has finished moving to the new location before you can use .getDojoShape().moveToFront().   Here's a modified version of the jsfiddle with the updated code: http://jsfiddle.net/23tDs/ ... View more

It's been a while since I tried this, but if you have a Graphic that uses a TextSymbol: 1) call map.toScreen() to get x,y screen coordinates of graphic; you might have to make adjustments based on the symbol.xoffset and symbol.yoffset. 2) call graphic.getDojoShape().getTextWidth() for the width, and graphic.symbol.font.size for the height (you might have to make additional adjustments if size is not pixel based).  Then add the desired padding.  Finally you might have to make additional offset adjustments if any of the coordinates are outside of the map extent. 3) create screen extent based on x, y, width, height, then call map.toMap() to get back real-world coordinates of bounding box. I believe there were a few other minor tweaks that were specific to what I was doing in the app, but this is the overall concept. ... View more

Careful, the previous solution assumes the geometry is a single-part polyline, which seems to be ok for this use case, but might not work in all situations, like when the geometry is retrieved from an external source like a Map or Feature Service. var lastPartIdx =  polyline.paths.length-1; var lastPntIdx = polyline.paths[lastPartIdx].length - 1; var lastPnt = polyline.getPoint(lastPartIdx , lastPntIdx); ...

Ken,  Try sending 'newExtent' to the console; it's probably incorrect.  Seems like the loop to find the selected well should come before you create the extent.  Here's another possible approach:     function zoomRow(id){         var grid = dijit.byId('grid');         var clickedWell = grid.getItem(id);                var selectedWell = null;        dojo.forEach(map.graphics.graphics,function(graphic){                     if((graphic.attributes) && graphic.attributes.FID === clickedWell.FID){             selectedWell = graphic.geometry;             return;           }         });        if(selectedWell != null){          var distance = 1000;           var newExtent = new esri.geometry.Extent({             "xmin": selectedWell.x - distance,             "ymin": selectedWell.y - distance,             "xmax": selectedWell.x + distance,             "ymax": selectedWell.y + distance,             "spatialReference":{"wkid":4326}           });           map.setExtent(newExtent);        }           } ...

Stephen,   also, you don't need to use esri.request, just listen for the layer 'onLoad' event and then the initialExtent is a property of the layer.  Using a geometry service to project the extent is the way to go. <!DOCTYPE html> <html>   <head>     <meta http-equiv="Content-Type" content="text/html; charset=utf-8">     <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">     <title>Zoom to non-WM dynamic layer</title>     <link rel="stylesheet" href="http://js.arcgis.com/3.6/js/esri/css/esri.css"/>     <style>       html, body, #mapDiv {         padding: 0;         margin: 0;         height: 100%;       }     </style>     <script src="http://js.arcgis.com/3.6/"></script>     <script>       dojo.require("esri.map");       dojo.require("esri.tasks.geometry");       var map;       var url = "http://loczy.mfgi.hu/ArcGIS/rest/services/TJAM/surf_ujfalu_t/MapServer/"       var gsUrl = "http://server.domain.com/arcgis/rest/services/Geometry/GeometryServer"; // url to your geometry service       function init(){         map = new esri.Map("mapDiv",{basemap: "gray"});         var dynamicMapServiceLayer = new esri.layers.ArcGISDynamicMapServiceLayer(url);         dynamicMapServiceLayer.on('load',function(){           var projectParams = new esri.tasks.ProjectParameters();           projectParams.geometries = [dynamicMapServiceLayer.initialExtent];           projectParams.outSR  = map.spatialReference;           var gs = new esri.tasks.GeometryService(gsUrl);           gs.project(projectParams).then(function(projectedGeometries){             var initialExtentWM = projectedGeometries[0];             map.setExtent(initialExtentWM);           });         });         map.addLayer(dynamicMapServiceLayer);       }       dojo.ready(init);     </script>   </head>   <body>     <div id="mapDiv"></div>   </body> </html> ...

If you want to modify the text displayed in the dialog, look at 'esri.bundle.identity.info' string.  Event though the '${server}' and '${resource}' template parts must be present, but you can hide them via css.  Also, the dialog and buttons are available to manipulate only after the dialog is created. esri.bundle.identity.info = "Please sign in to MYSITE.<span class='dijitOffScreen'>${server}${resource}</span>"; dojo.connect(esri.id,'onDialogCreate',function(){   esri.hide(esri.id.dialog.closeButtonNode);   esri.hide(esri.id.dialog.btnCancel_.domNode); }); ...

Thank you everybody for the continued support; we're getting close to releasing the Elevations SOE for 10.1.  We've had to make some breaking changes to accommodate requested use cases and it still needs some more testing.  Also, we're currently trying to add support for elevation datasets that have NoData values, something we have not done in the past.  We do not have a release date at this time, but I'll try to have it ready by the Dev Summit. Please do not use this sample code in production environments or in mission critical situations; it's just a sample. ... View more

You probably don't need 'dojo.connect(featureLayerEdit, "onEditsComplete", addResultsComplete);', instead just use the inline callback function in the applyEdits call.  Also, you're connecting this event many times, once for each map click; not sure if that is making a difference.  I would also hitch the inline calls to make sure you have the proper context.  Also, you need to get the updated feature from the feature layer again as the one currently in memory might not have the correct ObjectID that was assigned on the server.  This last step might not be necessary depending on what you need to do; in your case the ObjectID is provided by the FeatureEditResult object. featureLayerEdit.applyEdits([graphic], null, null, dojo.hitch(this, function(addResults){   if(addResult.success){     var query = new esri.tasks.Query();     query.objectIds = [addResult.objectId];     query.outFields = ["*"];           featureLayerEdit.queryFeatures(query, dojo.hitch(this, function(featureSet){       if(featureSet.features.length > 0){            var newFeature = featureSet.features[0];         newFeature.attributes["6"] = addResult.objectId + "_SOMEOTHERVAL";         featureLayerEdit.applyEdits(null, [newFeature], null);       }     }));    } }); I have not tested this, but it should be close to what you need. ...
