Select Map Feature from Grid

jaykapalczynski — Fri, 10 Dec 2021 21:51:23 GMT

I have a query Task that is running and creating a NEW graphics layer and displaying that in the map along with all the records from the query being displayed in a grid.

I now want to select the Feature in the map based on an ID select in the table. My example is a bit different than the ESRI example in that I don't have a Feature Layer Defined. I am querying the data and creating a Graphics Layer. I am trying the below and cant seem to get it working...

Thoughts?

queryTask.on("complete", function(event) {
   var highlightSymbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,
   new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,
   new Color([255, 0, 0]), 3), new Color([125, 125, 125, 0.35]));

   var symbol = new SimpleMarkerSymbol({
      // SNIP  Remove code for this example
   });
   var features = event.featureSet.features;
   var countiesGraphicsLayer = new GraphicsLayer();
   var featureCount = features.length;
   map.graphics.clear();
   for (var i = 0; i < featureCount; i++) {
      var graphic = features[i]; //Feature is a graphic
      graphic.setSymbol(symbol);
      graphic.setInfoTemplate(infoTemplate);
      map.graphics.add(graphic);
   }
 });


// fires when a row in the dgrid is clicked
   function selectState(e) {
     var fl = map.getLayer("countiesGraphicsLayer");
        fl.setSelectionSymbol(new SimpleFillSymbol().setOutline(null).setColor("#AEC7E3"));
        var query = new Query();
        query.objectIds = [parseInt(e.target.innerHTML, 10)];
            fl.selectFeatures(query, FeatureLayer.SELECTION_NEW, function(result) {
              if ( result.length ) {
                // re-center the map to the selected feature
                window.map.centerAt(result[0].geometry.getExtent().getCenter());
              } else {
                console.log("Feature Layer query returned no features... ", result);
              }
            });
    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You may be able to use a feature layer for this and overwrite the renderer on the feature layer so that it returns whatever symbol you want.

If there is some other reason you need to use a graphics layer then you may have to search through the list of graphics added to the map manually based on some unique key rather than using queryFeatures. I'm not sure how to programmatically select something in 3.XX so I can't comment on that.

I think map.graphics will have a list of graphics added to the base graphics layer and you should be able to search that list based on the unique key that you used in your table.

The query task example shows graphics layer being created...not sure how to create a feature layer and do as you stated.

Could you link to the sample please?

This is a follow-up for this thread: https://community.esri.com/thread/192648-return-results-options

Jay,

Here is how you would do it for your sample code (I have comments in the code):
