DataGrid with zoom button...button doesn't show and won't zoom

MichelleRogers1

I am new at working with ArcGIS API for JavaScript and have come across the following problem:

I am working with the sample DataGrid with zoom button to get my data to zoom to a specific point, but not only is the data not zooming, the button isn't even showing inside the grid. Instead it is showing the OBJECTID. Any suggestions on how to fix this?

Here is part of the JavaScript code I am working with:

policeUnits2 = new esri.layers.FeatureLayer
("http://GIS10204:6080/arcgis/rest/services/GeoEvent/gx440P/MapServer/0",{
mode:esri.layers.FeatureLayer.MODE_SELECTION,
outFields:["VehicleId", "Velocity", "OBJECTID"]
});

//define a selection symbol
var highlightSymbol = new esri.symbol.SimpleFillSymbol().setColor( new dojo.Color([50,205,50,.25]));
policeUnits2.setSelectionSymbol(highlightSymbol);

dojo.connect(policeUnits2,'onLoad',function(layer){
var query = new esri.tasks.Query();
query.where = "1=1";
layer.queryFeatures(query,function(featureSet){
var items = dojo.map(featureSet.features,function(feature){
   return feature.attributes;
});
var data = {
   identifier:"OBJECTID",
   items:items};
store = new dojo.data.ItemFileReadStore({data:data});
grid.setStore(store);
grid.setSortIndex(1,"true"); //sort on VehicleId
});
});
map.addLayer([policeUnits2]);

//modify the grid so only the VehicleId field is sortable
grid.canSort = function(col){ if(Math.abs(col) == 2) { return true; } else { return false; } };

function makeZoomButton(id){
var zBtn = "<div data-dojo-type='dijit/form/Button'><img src='images/zoom.png'";
zBtn = zBtn + " width='18' height='18'";
zBtn = zBtn + " onClick=\"zoomRow('"+id+"')\"></div>";
return zBtn;
}
function zoomRow(id){
policeUnits2.clearSelection();
var query = new esri.tasks.Query();
query.objectIds = [id];
policeUnits2.selectFeatures(query,esri.layers.FeatureLayer.SELECTION_NEW,function(features){
//zoom to the selected feature
var unitExtent = features[0].geometry.getExtent().expand(1.0);
map.setExtent(unitExtent);
});
}

This is the html code:
<body class="claro">
<div data-dojo-type="dijit/layout/BorderContainer" style="width: 100%; height: 100%">
<div data-dojo-type="dijit/layout/ContentPane" id="header" data-dojo-props="region:'top'">City of Naples Police AVL
   <div id="locateContainer">
    <label>Address: </label>
    <input id='addressInput'></input>
   </div>
</div>
<div id="mapDiv" data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region:'center'">
   <div id="BasemapToggle" ></div>
   <div id="HomeButton"></div>
</div>
<div data-dojo-type="dijit/layout/ContentPane" id="leftPane" data-dojo-props="region:'leading'">
   <table data-dojo-type="dojox/grid/DataGrid" jsid="grid" id="grid" selectionMode="none">
    <thead>
     <tr>
      <th field="OBJECTID" formatter="makeZoomButton" width="25px">
      <img alt="+" src="images/zoom.png"/>
      </th>
      <th field="VehicleId" width="100px">Vehicle Id</th>
     </tr>
    </thead>
   </table>
</div>
        </div>
</body>

Here is a picture of what my viewer looks like

Hi Michelle,

I'm not sure why the zoom.png is not showing in your datagrid, but I think I know why it is not zooming to your data. Since you are using point data, you will need to define an extent. Point data will only have an X & Y coordinate value. Here is function you can add to do this:

function pointToExtent(map, pointX, pointY, tolerance){
    var xmin = pointX - tolerance;
    var ymin = pointY - tolerance;
    var xmax = pointX + tolerance;
    var ymax = pointY + tolerance;
    
    return new esri.geometry.Extent(xmin, ymin, xmax, ymax, map.spatialReference)
}

You can then update the zoomRow function to use this:

function zoomRow(id){
    policeUnits2.clearSelection();
    var query = new esri.tasks.Query();
    query.objectIds = [id];
    policeUnits2.selectFeatures(query,esri.layers.FeatureLayer.SELECTION_NEW,function(features){
      extent = pointToExtent(map, features[0].geometry.x, features[0].geometry.y, 6)
      map.setExtent(extent);
    });
}

Also, I believe you will need to update the higlightSymbol since you are using point data. Try using the SimpleMarkSymbol. Ex:

var highlightSymbol = new esri.symbol.SimpleMarkerSymbol({
      "color": [255,255,255,64],
      "size": 12,
      "angle": -30,
      "xoffset": 0,
      "yoffset": 0,
      "type": "esriSMS",
      "style": "esriSMSCircle",
      "outline": {
        "color": [0,0,0,255],
        "width": 1,
        "type": "esriSLS",
        "style": "esriSLSSolid"
      }
    });
policeUnits2.setSelectionSymbol(highlightSymbol);

I added the code that you suggested, but it still doesn't work. I am going to copy and paste the entire code here, so you can see if there is a conflict with something else that I am doing.

With the AMD model, it's not as easy to call a function from HTML. It's recommended to call the dom/dijit, and then execute the event. In the code you provided, you are calling the 'makeZoomButton' from the DataGrid. I couldn't figure out how to execute this function by calling the DataGrid dijit, however, I have a workaround that you can use. Add the following to your code:

var grid1 = dijit.byId("grid");
on(grid1,"rowClick", onRowClickHandler)
                              
function onRowClickHandler(evt){
             policeUnits2.clearSelection();
                    
             var id= grid1.getItem(evt.rowIndex).OBJECTID;                    
             var query = new esri.tasks.Query();
             query.objectIds = [id];
             policeUnits2.selectFeatures(query,esri.layers.FeatureLayer.SELECTION_NEW,function(features){
             extent = pointToExtent(map, features[0].geometry.x, features[0].geometry.y)
             map.setExtent(extent);                      
             });
}

Jake,

Would I just add this code under the code that I already have for function zoomRow, or do I need to replace code that is there already?

Thanks!

You can delete the 'zoomRow' function and add this code.

MichelleRogers1

Jake,

I just tried it, and it's still not zooming. Would I change the code in makeZoomButton below, that shows the zoomRow, since it is no longer there, and what would I replace it with?

Sorry, I am new to this kind of coding, and I have just been taking code snippets out of ESRI samples and putting them together, so any help is appreciated.

zBtn = zBtn + " onClick=\"zoomRow('"+id+"')\"></div>";

MichelleRogers1

Also, when I use the Debugger tools in Internet Explorer, it is telling me that 'on' is undefined in

on(grid1, "rowClick", onRowClickHandler)

That was my mistake. I forgot to mention that you will need to import the dojo/dom and dojo/on modules. Try the attached.

index.txt.zip

MichelleRogers1

I tried literally copying and pasting your exact code that you gave me, still no luck with the zoom function. Now it is giving me the error:

dojo.io.script error Error: Failed to execute query.

This is when I click on the OBJECTID. The map is not showing once I click either. This is the screenshot:

[ATTACH=CONFIG]31024[/ATTACH]

We have another ESRI person on it from talking on the phone with him yesterday, so I think we have something that has stumped two of you.:)

Take a look at the jsfiddle here. The only thing I changed was the map extent, and the service to the Vehicle layer.

MichelleRogers1

This data is coming in from the GeoEvent Processor. Could this have an effect on the zoom to? Do we need to contact someone with GeoEvent Processor experience?

I was able to get the issue narrowed down to an issue with the Home Button, Basemap Toggle, and InfoTemplate interferring with the DataGrid. I started out with the DataGrid with zoom button sample code and started entering items until it no longer worked to get to this point. Is there anything that can be done to get those three functions into code with the DataGrid? When I go to insert those three functions, the entire screen except the header is completely blank. I am also trying to get the DataGrid to do an automatic refresh as well, so any help you can give me with that would be appreciated as well.

Here is the code I am working with now.

Hi Michelle
I have some time to take a look at your code.

In the future, you should use http://jsfiddle.net to generate a working, live sample.
It makes debugging much easier.

Jonathan,
I figured out my issue with the Basemap Toggle, Home Button, and Info Template. I was trying to pass them through another function within the init function, which you do not need to do. I just had to add the dojo.require statements for the three and then when I said new, instead of just:

var home = new HomeButton

use:

var home = new esri.dijit.HomeButton

I am still looking at how I can do an automatic refresh on the DataGrid itself, so any help there would be appreciated.

Hi Michelle.

I spent some time on this yesterday but did not realize your application was written in the old style so I put it aside.
Jake's code is in the newer style (AMD) and on the right track but I personally would use a dgrid instead of DataGrid.

As for the issue, yep that's exactly it!
When coding in the legacy style, you will need to require each module individually and invoke using the same path pattern.

New Style (AMD):

require([        
  "esri/map",
  "esri/dijit/HomeButton"
], function (Map, HomeButton) {
  var home = new HomeButton();
});

Old Style (Legacy):

dojo.requrie("esri.Map");
dojo.requrie("esri.dijit.HomeButton");
var home = new esri.dijit.HomeButton();

Is there any reason you are writing your application in the legacy style?
It will be deprecated sooner than later and I only bring it up so you aren't forced to rewrite the entire application somtime in the next year.

Jonathan,

We tried using AMD from the samples for Home Button, Basemap Toggle, and Info Template, but when combined with the DataGrid, the DataGrid was not functioning anymore. We were told to use DataGrid for the functionality that we wanted by an ESRI Technical Support person (Noah). So, we decided to work in the reverse order, and the original code for DataGrid with zoom button in the ESRI Samples was written in Legacy. So, I went in and added those functions in the Legacy code to get the entire application to work together. If there is a way I can get everything to work in AMD, I am open to suggestions. Like I had said at the beginning of the thread, I am new to coding with ESRI, and fairly new to coding in general, so any help you can give me is very much appreciated.

Michelle
