How to search just 1 graphic element in a FeatureSet on widget

EvelynHernandez · ‎07-30-2014

Hello.

Im doing a widget that has a grid with the result of a query that i did previously.

My question is. When i click on the grid i can get one of the attributes in the grid with the "event.currentTarget.selectedItem.ATTRIBUTETOCHOOSE"

and then i do another query asking the geometry of that attribute to make a zoom in the map when its selected.

The thing is, i dont wanna make another query to get the featureSet of that attribute, because in the previous query i have them all. So how i can search just for the "selected" attribute in the previous featureSet that i used already?

Thanks.

My code is this one, and it works but i want to change it for not to do the second query.

This is the code for the query to ask some routes on the arcgis srv and put the data in a grid:

public function searchRoute():void

{

var queryTaskRuta:QueryTask = new QueryTask();

queryTaskRuta.showBusyCursor = true;

queryTaskRuta.url = "XXXXXXXXXXX";

queryTaskRuta.useAMF = false;

var queryRutaSelected:Query = new Query();

queryRutaSelected.returnGeometry = true;

queryRutaSelected.outFields = ["*"];

//queryRutaSelected.where = "ARCGIS.dbo.CLIENTES_DATA_DATOS_006.nis IN (118936, 118934)";

queryRutaSelected.where = "ARCGIS.dbo.CLIENTES_DATA_DATOS_006.cd_sector =" + CboSector.selectedIndex + " and ARCGIS.dbo.CLIENTES_DATA_DATOS_006.cd_area= " + TxtArea.text

queryTaskRuta.execute(queryRutaSelected, new AsyncResponder(onResult, onFault));

function onResult(featureSet:FeatureSet, token:Object = null):void

{

if (featureSet.features.length == 0){

Alert.show("Ruta no encontrada","Busqueda de Rutas");

}

else{

try{

setBusyCursor();

for (var x:Number=0; x < featureSet.features.length; x++)

{

//agregar a variables y luego al objeto que se muestra en la tabla...

var nis:Number = featureSet.features.attributes["ARCGIS.dbo.CLIENTES_DATA_DATOS_006.nis"];

featureSet.features.attributes["categoria"] = categoria;

featureSet.features.attributes["estado_final"] = estado_final;

coleccion.addItem(featureSet.features.attributes);

fset=featureSet;

var mp:MapPoint=featureSet.features.geometry as MapPoint;

var myGraphic:Graphic = new Graphic(new MapPoint(mp.x,mp.y, new SpatialReference (102100)));

myGraphic.symbol=new SimpleMarkerSymbol("circle",8,0xFF3300)

graphicsLayer.add(myGraphic);

map.zoomTo(featureSet.features.geometry);

map.level = 15;

map.addLayer(graphicsLayer);

}

}catch(err:Error){

Alert.show("Error al graficar","Route Search");

}

myViewStack.selectedIndex = 1;

removeBusyCursor();

}

}

function onFault(info:Object, token:Object = null):void

{

Alert.show("Ruta No existe","Route Search");

removeBusyCursor();

}

}

This is the code when the user click on the grid and extracts the "nis" attribute to search again in another query to get the geometry to zoom it on the map, also put the InfoWindow with some of the data of the clicked field on the grid. (i want to change this for using the featureSet that i have in the other query and search the clicked from there)

protected function gridTest_clickHandler(event:MouseEvent):void

{

var seleccionado:String = new String(event.currentTarget.selectedItem.nis);

//Configuración ventana infoWindow datos

var popUpInfo:PopUpInfo = new PopUpInfo;

popUpInfo.title = seleccionado;

popUpInfo.description = String(event.currentTarget.selectedItem.zona) + "<br>" + String(event.currentTarget.selectedItem.direccion_resu);

var q:QueryTask = new QueryTask();

q.showBusyCursor = true;

q.url = "xxxxxxxxxxxxx";

q.useAMF = false;

var r:Query = new Query();

r.returnGeometry = true;

r.where = "ARCGIS.dbo.CLIENTES_DATA_DATOS_006.nis =" + seleccionado;

q.execute(r, new AsyncResponder(onResult, onFault));

function onResult(featureSet:FeatureSet, token:Object = null):void

{

try{

for each (var myGraphic:Graphic in featureSet.features)

{

myGraphic.symbol=new SimpleMarkerSymbol("diamond",10,0x00FF00)

var mp:MapPoint=featureSet.features[0].geometry as MapPoint;

graphicsLayer.add(myGraphic);

map.zoomTo(featureSet.features[0].geometry);

map.level = 16;

//Configuración ventana infoWindow con graphic

popUpRenderer.popUpInfo = popUpInfo;

popUpRenderer.graphic = myGraphic;

map.infoWindow.content = popUpRenderer;

map.infoWindow.contentOwner = popUpRenderer.graphic;

map.infoWindow.show(mp);

}

}catch(err:Error){

Alert.show("no se pudo hacer zoom al equipo seleccionado");

}

}

function onFault(info:Object, token:Object = null):void

{

Alert.show("nis no encontrado");

}

}

Here is a sample that works with joined data.

The labelFunction getLabel allow you to just add your data that is nested to the datagrid without all your steps of simplifying the field name.

Ok, i will try this and i will tell u how is going later.

Thanks for ur patience Robert, i appreciate it too much.

Regards

EvelynHernandez · ‎07-31-2014

Robert,

Thank you so much for your help. I resolve the problem with the joins and now the widget works perfectly.

I have another question about widgets and the map, but i will post it in another place.

I give the answered question already.

Regards.

Evelyn,

Glad I could help. I will look for your new question.
