Thanks for taking a look at it, unfortunately I still get the same error. Could the issue also be in- var ResultEnv = query.geometry.getExtent().expand(10.0); ?? Yes, you need to change make similiar changes on you showResults function. ... View more

Thanks again for the reply! I am trying to set-up a situation where if the user of the map manually selects overlapping features using the Identify task, both results will display in seperate datagrids at the bottom of the screen. I have it working if only one layer is selected, results are displayed in the datagrid. I also have it working where if two layers are selected, they highlight as such on the map. I am just stuck on how to show the results of the selection in 2 datagrids at the bottom of the page. I am also open to having a propmt that allows the user to chose which results to show after selecting both layers. I hope that makes sense. The part that seems to be broken is where I try and get results for both layers using the && operator. The alert does not even display in the section of code.Below is the relevant code. I really appreciate any advice you have!! Sorry to be such a newbie.:confused: //SELECT STUFF   dojo.connect(map, 'onLoad', function(theMap) {            navToolbar.deactivate();            identifyTask = new esri.tasks.IdentifyTask("http://slcarcgisdev1/SLCOGIS/rest/services/public/Surveyor/MapServer");                       identifyParams = new esri.tasks.IdentifyParameters();            identifyParams.tolerance = 3;            identifyParams.returnGeometry = true;            identifyParams.layerIds = [0,2];            identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL;            identifyParams.width  = map.width;            identifyParams.height = map.height;                         //initialize the toolbar           toolBar = new esri.toolbars.Draw(map);           dojo.connect(toolBar, "onDrawEnd",onDrawEnd);                    navToolbar.deactivate();           //resize the map when the browser resizes           dojo.connect(dijit.byId('map'), 'resize', map,map.resize);                             });                                      function onDrawEnd(extent){           navToolbar.deactivate();           executeIdentifyTask(extent);       }                  function executeIdentifyTask(geom) {         //clear the graphics layer         map.graphics.clear();       var polygonSymbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DOT, new dojo.Color([151, 249,0,.80]), 3), new dojo.Color([151, 249, 0, 0.45]));         var markerSymbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_CIRCLE, 20, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([0, 0, 0]), 1), new dojo.Color([25,50,225,0.3]));                 identifyParams.geometry = geom;         identifyParams.mapExtent = map.extent;         identifyTask.execute(identifyParams,function(response){             var controlItems = [];             var surveyItems = [];                                 dojo.forEach(response,function(result){                var feature = result.feature;                 //add selected feature to graphics layer                 feature.setSymbol(polygonSymbol);                 feature.setSymbol(markerSymbol);                 map.graphics.add(feature);                              if (result.layerName === 'surveys' && result.layerName === 'Control Points'){              alert(result.layerName);             showSurveysNameGrid();             surveyItems.push(feature.attributes);                        showPointNameGrid();            controlItems.push(feature.attributes);                                                             var surveysStore = new dojo.data.ItemFileReadStore({data:{identifier:'DOCUMENT',items:surveyItems}});             var grid = dijit.byId('grid5');            grid.setStore(surveysStore);                                   var controlStore = new dojo.data.ItemFileReadStore({data:{identifier:'POINT_NAME',items:controlItems}});             var grid = dijit.byId('grid4');            grid.setStore(controlStore);                                          }else if(result.layerName === 'Control Points'){                    alert(result.layerName);                  showPointNameGrid();                                   controlItems.push(feature.attributes);                      searchType = "selControl";                                        //update the data grid                      var controlStore = new dojo.data.ItemFileReadStore({data:{identifier:'POINT_NAME',items:controlItems}});            var grid = dijit.byId('grid4');            grid.setStore(controlStore);                                                   }else if(result.layerName === 'surveys'){                                     alert(result.layerName);                                   showSurveysNameGrid();                  surveyItems.push(feature.attributes);                     searchType="selSurveys2";                                     var surveysStore = new dojo.data.ItemFileReadStore({data:{identifier:'DOCUMENT_N',items:surveyItems}});             var grid = dijit.byId('grid5');            grid.setStore(surveysStore);                                }                                                    });                                                               });       } You might want to change you logic flow in your function.

Thanks so much for the answer!:) That is what I was trying to accomplish with the code I originally posted.

Hi all, I found an app here : http://help.arcgis.com/en/webapi/javascript/arcgis/demos/find/find_map_datagrid.html How do you make the datagrid on this app editable ? Any sample on editing datagrid ? I need guidance Thanks First of all, change the data store from ItemFileReadStore to ItemFileWriteStore. Also make the field (or cell) editable - editable ="true". If you want the data changed in Database, you also need to make the layer as a featurelayer to allow data editing such that you could use applyEdits... ... View more

I'm trying to use the code sample here to use URL parameters to select one or more POINT features and zoom the map to those features. I have configured it using one of my polygon features and it works but I'm trying to use it for a point feature. When I try passing this URL parameter the symbol appears around the point but the map does not zoom in or display the points information. Also I get this error- TypeError: query.geometry is null Does anyone know what I need to add to my code to allow this to work properly? I've tried a few different ways but not having much luck. From the error message, I think the problem lies in the queryExtent in your executeQueryTask(evt) function. Try this to see if it works: function executeQueryTask(evt) {     query.where = "";     var centerPoint = evt.mapPoint;     var mapWidth = theMap.extent.getWidth();     var pixelWidth = mapWidth/theMap.width;     //Calculate a 10 pixel envelope width (5 pixel tolerance on each side)      var tolerance = 5 * pixelWidth;         var queryExtent = new esri.geometry.Extent(centerPoint.x -tolerance, centerPoint.y -tolerance, centerPoint.x +tolerance, centerPoint.y +tolerance, theMap.spatialReference);      query.geometry = queryExtent;     queryTask.execute(query, showResults); } ...

I've fiddled around with dojo's content panes and I'm pretty sure that need to be defined a region where they are supposed to be located (top, left, center, right & bottom). BTW, can a width be inherited from a parent style that easily with just style="width: inherit;"? Since your two map panels are all within another div. I would try this: div.mappingTab #mapM { position:absolute; width:100%; height:99%; padding:0; } div. analysisTab #mapA { position:absolute; width: 800px; height: 300px; right:10px; top:10px; box-shadow:1px 1px 10px black; } ...

Hi all, I have a Javascript web map in which the user manually selects layers by dragging a box, using the Identify Task. I have it working where if features from one layer are selected, the results are displayed in a datagrid. The problem I am having is if two layers overlap and the user selects them both, I can't figure out how to display results for both. I have tried multiple things and am yet to come up with a solution. I am open to either having both datagrids displayed at the bottom, or giving the user a choice through a pop-up window of which grid results to show. The last chunk of the else/if statement where I try to put both the layers together does not seem to be working....any ideas????

Thanks Angela.  I can definitely accomplish this, however I don't know how I can ensure that I am measuring straight line distance from end point to end point (Shortest route?) as opposed to distance along the polyline.

I've seen some hiccups with the overwriteOutput command after scripts have been executed and then it's added.  Try deleting the table, restarting Pythonwin/IDLE, and then re-execute the script. env.overwriteOutput =true  has no impact on arcpy.FeatureClassToFeatureClass_conversion.  Either use arcpy.CopyFeatures_management, or delete feature class prior to arcpy.FeatureClassToFeatureClass_conversion. Something like this: outFC =outLocation +os.sep + outFeatureClass  #need import os. (or use out FC =outLocation +"\\"+ outFeatureClass) if arcpy.Exists(outFC)==True:           arcpy.Delete_management(outFC) ... View more

I have quite a few scheduled tasks which start a batch file and then start a python script from there. You may have a quirk that the python script encounters which causes it to bail immediately. Sometimes what helps is to add a line (in the batch file itself) that will write the processing output to a text file. Something like... PythonScript.py >  C:\Log\LogFile.txt 2>&1 I also have the Python script itself write out a log file in case there are any errors I can't see in the command line log file. Something like ... import arcpy, os outtable = open(r"C:\Log\PythonLog.txt", "w") ... ((((variables here)))) try: ((((indented code here))))     outtable.write("Some sort of text string here to let you it worked") except arcpy.ExecuteError:     outtable.write(arcpy.GetMessages()) outtable.close() If the Python script succeeds you'll get that 'success text.' If not it may give you an idea on what the error is. Depending on if and when an error occurs makes the difference on which file you will find it in. Hope this helps! Did you specify the path of python.exe in your batch file? ... View more

Thanks Heming. I think conceptual your idea of projecting the AOI is the way to go. However, I don't know how to go about that from a technical standpoint. It would be easy if my AOI was an already established layer. In this case it is an interactive graphic that only exists once the user draws it. I don't know how to project those as I'm new to developing ArcGIS Server apps. I am including the code for the esri sample I modified to use our data and the online basemap. Note that the MapServer referenced in the code is now in my state plane SR, but that should be irrelevant. I can always re-create it to the SR I need to make the app function with the basemap (wkid:102100 I believe is also wkid: 4326).
