Hi all, I am using JQuery drag function to allow users to drag their panels around. It works great but I am experiencing some issues when dragged out of the document to the right. It seems like  it is causing a white margin to appear to the right of the window. Any idea? jsbin. ​ ... View more

Hi all, I am trying to get coordinates from a point drawn on a map. Just like this sample​, I want users to have the choice of markers by letting them choose their markers using a drop down. The problem is that I can get the coordinates just fine when draw a point (by default) but when I switch marker I cant get the coordinates. Any idea why? 1) Get the coordinates for point drawn:   var geometry = evt.geometry;                     var symbol = dom.byId("symbol").value;                     if (symbol) {                         symbol = eval(symbol);                     } else {                         switch (geometry.type) {                             case 'point':                                 symbol = tb.markerSymbol;                                 var mp = webMercatorUtils.webMercatorToGeographic(geometry);                                 dom.byId("coordinates").innerHTML = mp.x.toFixed(3) + ", " + mp.y.toFixed(3);                                 break; 2) UI drop down choice: <div class="form-group">                     <select class="form-control" id="symbol">                         <option value="">--- Symbol Options ---</option>                         <option value="">--- Point ---</option>                         <option value="new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_SQUARE, 7, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new color([255,0,0]), 1), new color([255,0,0,1]))">Default</option>                         <option value="new SimpleMarkerSymbol().setColor(new color([0, 0, 255]))">Circle</option>                         <option value="new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_DIAMOND, 20, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new color([0,0,0]), 1), new color([255,255,0,0.5]))">Diamond</option>                         <option value="">--- Simple Line ---</option>                         <option value="new SimpleLineSymbol()">Default</option>                         <option value="new SimpleLineSymbol(SimpleLineSymbol.STYLE_DASH, new color([255,0,0]), 3)">Dash</option>                         <option value="new SimpleLineSymbol(SimpleLineSymbol.STYLE_DOT, new color([255,0,0]), 5)">Dot</option>                         <option value="">--- Cartographic Line Symbols ---</option>                         <option value="new CartographicLineSymbol()">Default</option>                         <option value="new CartographicLineSymbol(CartographicLineSymbol.STYLE_SOLID, new color([255,0,0]), 10, CartographicLineSymbol.CAP_ROUND, CartographicLineSymbol.JOIN_ROUND)">Solid, round cap, round join</option>                         <option value="new CartographicLineSymbol(CartographicLineSymbol.STYLE_SOLID, new color([255,0,0]), 10, CartographicLineSymbol.CAP_SQUARE, CartographicLineSymbol.JOIN_BEVEL)">Solid, square cap, bevel join</option>                     </select>                 </div> ...

Hi all, I am trying to create a drop down menu which would allow users to select the unit of their choice when measuring polygons and poly lines. Drop down is here: <select id="dropdown" class="selectpicker">                     <option value="UNIT_SQUARE_MILES">Acres</option>                     <option value="UNIT_ARES">Ares</option>                     <option value="UNIT_HECTARES">hectares</option>                     <option value="UNIT_SQUARE_FEET">Square Feet</option>                     <option value="UNIT_SQUARE_KILOMETERS">Square Kilometers</option>                     <option value="UNIT_SQUARE_METERS">Square Meters</option>                     <option value="UNIT_SQUARE_MILES">Square Miles</option>                 </select> Selected value: var areasUnits = $('option:selected', $('#dropdown')).val();                     var geometry = evt.geometry;                     var symbol = dom.byId("symbol").value;                     if (symbol) {                         symbol = eval(symbol);                     } else {                         switch (geometry.type) {                             case 'point':                                 symbol = tb.markerSymbol;                                 break;                             case 'polyline':                                 symbol = tb.lineSymbol;                                 var lengthParams = new LengthsParameters();                                 lengthParams.polylines = [geometry];                                 lengthParams.lengthUnit = GeometryService.UNIT_FOOT;                                 lengthParams.geodesic = true;                                 geometryServiceLength.lengths(lengthParams);                                 break;                             case 'polygon':                                 symbol = tb.fillSymbol;                                                                 var areasAndLengthParams = new AreasAndLengthsParameters();                                 areasAndLengthParams.areaUnit = GeometryService.areasUnits;                                 areasAndLengthParams.calculationType = "geodesic";                                 geometryService.simplify([geometry], function (simplifiedGeometries) {                                     areasAndLengthParams.polygons = simplifiedGeometries;                                     geometryService.areasAndLengths(areasAndLengthParams);                                 });                                 break;                             case 'freehandpolygon':                                 symbol = tb.fillSymbol;                                 var areasAndLengthParams = new AreasAndLengthsParameters();                                 areasAndLengthParams.areaUnit = GeometryService.UNIT_ACRES;                                 areasAndLengthParams.calculationType = "geodesic";                                 geometryService.simplify([geometry], function (simplifiedGeometries) {                                     areasAndLengthParams.polygons = simplifiedGeometries;                                     geometryService.areasAndLengths(areasAndLengthParams);                                 });                                 break;                             default:                         }                     } Any ideas ...

Hi all, I am using this sample​ to get the measurements for my draw toolbar. It works great. However, I would like, in addition to this to measure polylines as AreaandLength only take polygons as input. To achieve this I am using esri/tasks/LengthsParameters. The combination of the two work but I keep getting this error: "Error: Unable to complete operation.(…)" altough it returns the right number. Any idea? Thanks, Alex var geometryService = new GeometryService("http://webgisdevint1/arcgis/rest/services/Utilities/Geometry/GeometryServer");                 geometryService.on("areas-and-lengths-complete", outputAreaAndLength);                 var geometryServiceLength = new GeometryService("http://webgisdevint1/arcgis/rest/services/Utilities/Geometry/GeometryServer");                 geometryServiceLength.on("lengths-complete", outputLength);                 //Get graphics to Graphic Layer dedicated for draw                 function addGraphic(evt) {                                         map.graphics.clear();                     var geometry = evt.geometry;                     var symbol = dom.byId("symbol").value;                     if (symbol) {                         symbol = eval(symbol);                     } else {                         switch (geometry.type) {                             case 'point':                                 symbol = tb.markerSymbol;                                 break;                             case 'polyline':                                 symbol = tb.lineSymbol;                                 break;                             case 'polygon':                                 symbol = tb.fillSymbol;                                 break;                             case 'freehandpolygon':                                 symbol = tb.fillSymbol;                                 break;                             default:                         }                     }                     var areasAndLengthParams = new AreasAndLengthsParameters();                     areasAndLengthParams.areaUnit = GeometryService.UNIT_ACRES;                     areasAndLengthParams.calculationType = "geodesic";                     geometryService.simplify([geometry], function (simplifiedGeometries) {                         areasAndLengthParams.polygons = simplifiedGeometries;                         geometryService.areasAndLengths(areasAndLengthParams);                     });                     var lengthParams = new LengthsParameters();                     lengthParams.polylines = [geometry];                     lengthParams.lengthUnit = GeometryService.UNIT_METER;                     lengthParams.geodesic = true;                     geometryServiceLength.lengths(lengthParams);                                       map.getLayer("drawGL").add(new Graphic(geometry, symbol));                 } function outputAreaAndLength(evtObj) {                     var result = evtObj.result;                     console.log(json.stringify(result));                     dom.byId("area").innerHTML = result.areas[0].toFixed(3) + " acres";                 }                 function outputLength(evtObj) {                     var result = evtObj.result;                     console.log(json.stringify(result));                     dom.byId("length").innerHTML = result.lengths[0].toFixed(3) + " feet";                 } ...
