How to set a result of a query in a dgrid's memory store in a module

PriyaRam — Sat, 16 Jan 2016 00:57:45 GMT

I have a AMD module, which has a public function, to load a feature layer and when the results return I need to populate a grid. I'm having trouble with scope accessing the grid craeted in a private method. I 'm trying to use this.set and watch on the object change , but calling "this.set" gives me a Type error. Please advise, I'm new to dojo framework.

//Constructor function

constructor: function (options, srcRefNode) {

// results holder

this.set("results", []);

// watch updates of public properties and update the widget accordingly

this.watch("results", this._updateMemoryStore);

// Update geocoder nodes

_updateMemoryStore: function () {

var items = this.get("results");

//idProperty must be set manually if value is something other than 'id'

var memStore = new Memory({

data: items,

idProperty: "ObjectID"

});

console.log(memStore);

onLoadBndry: function() {

...

queryTask.disableClientCaching = true;

queryTask.useAMF = false;

queryTask.showBusyCursor = true;

queryTask.execute(query,this._showResults);

_showResults:function(featureSet) {

console.log("_showResults");

var items = array.map(featureSet.features, function(feature) {

return feature.attributes;

});

this.set("results", items); \\TypeError: this.set is not a function

Hi Priya,

You need to use dojo's lang.hitch on _showResults function call to set the execution scope.

include "dojo/_base/lang" AND

onLoadBndry: function() {

...

queryTask.disableClientCaching = true;

queryTask.useAMF = false;

queryTask.showBusyCursor = true;

queryTask.execute(query, lang.hitch(this, this._showResults));

You might have to do this for call to _updateMemoryStore as well

this.watch("results", lang.hitch(this, this._updateMemoryStore));
