show domain in dgrid/OnDemandGrid

AuraRamos_Lora1 — Wed, 15 Jul 2015 17:04:30 GMT

Could you help me, please to show domain in dgrid, this is functionally in infowindow but in grid puts the code, not the description.of domain.

var outFieldsProy = ["PROYECTO", "NOMBRE", "ESC250", "AERONAVE"]

var gridProy = new (declare([Grid, Selection,ColumnHider, ColumnReorder, ColumnResizer]))({

bufferRows : Infinity,

columns : {

PROYECTO : "Proyecto",

NOMBRE : "Nombre",

ESC250 : "Escala 250",

AERONAVE : "Aeronave"

}

}, "divGrid");

function populateGrid(results) {
// var gridData;

            dataQuakes = arrayUtils.map(results.features, function (feature) {
                return {
                    "PROYECTO": feature.attributes[outFieldsProy[0]],
                    "NOMBRE": feature.attributes[outFieldsProy[1]],
                    "ESC250": feature.attributes[outFieldsProy[2]],
                    "AERONAVE": feature.attributes[outFieldsProy[3]]

};

});

var memStore = new Memory({

data: dataQuakes

});

gridProy.set("store", memStore)

}

Thanks

you should find something here QueryTask and coded domain values

Thank you thejus kambi

This function _getCodedValue: function (layer, fieldName, fieldValue, typeID) must be before this?:

function populateGrid(results) {
            // var gridData;
            dataQuakes = arrayUtils.map(results.features, function (feature) {
                return {
                    "PROYECTO": feature.attributes[outFieldsProy[0]],
                    "NOMBRE": feature.attributes[outFieldsProy[1]],
                    "ESC250": feature.attributes[outFieldsProy[2]],
                    "AERONAVE": feature.attributes[outFieldsProy[3]]
                    };
            });

and other question, ¿which is typeID?

Regards

Ignore that as you might not have it. It is to be use when you have a subtypes in FeatureLayer.

You can use the fields property of the query result. Select the field which has domain.

var field = results.fields["< field name >"]

var codedValueDomain = field.domain;

and use this domain and get the code value, while looping through the features and prepare the data for grid.

I´m sorry, but I have other question.

My query result is a featureset. how can I convert this to fields type?

//Inicializa el query
            var queryProy = new Query();
            queryProy.geometry = geometryInput;
            //Wire the layer's selection complete event
            operationsPolygonLayer.on("selection-complete", populateGrid);
            // Transforma la selección
            operationsPolygonLayer.selectFeatures(queryProy, FeatureLayer.SELECTION_NEW);

because

var field = results.fields["AERONAVE"];

is undefined

Thanks again
Regards

I thought you are using QueryTask to get the results. Now I see you are using featureLayer. The FeatureLayer has fields property use that instead.

I am having a hard time getting coded domains to show up.

What part of the code did you put this into:

 var field = feature.fields["<Priority>"]
var codedValueDomain = field.domain;

I am using this template

Hello Rickey,

You need to do if before you set the data to dgrid. like below

statesLayer.on("load", function(evt) {
          var query = new Query();
          query.where = "1=1";
          evt.layer.queryFeatures(query, function(featureSet) {
            var items = array.map(featureSet.features, function(feature) {
                   var attributes = lang.clone(feature.attributes);
                   var fields = statesLayer.fields;
                   //Replace the attributes values for domain values here.
                   return attributes;
            });

            //idProperty must be set manually if value is something other than 'id'
            var memStore = new Memory({
              data: items,
              idProperty: "ObjectID"
            });
            window.grid.set("store", memStore);
            window.grid.set("sort", "STATE_NAME");

            grid.on(".field-ObjectID:click", function(e) {
              //retrieve the ObjectId when someone clicks on the magnifying glass
              if (e.target.alt) {
                zoomRow(e.target.alt);
              }
            });
          });
        });

I get an error of:

Cannot read property '<Priority>' of undefined

where priority is my field name

Re: show domain in dgrid/OnDemandGrid

thejuskambi — Fri, 04 Dec 2015 16:30:56 GMT

you should try without the "<" ">" signs. also feature does not contain the fields property. if you see my code, I am getting the fields from the stateLayer and not feature.

Thejus,

Do I add a formatter to the field in the columns section?

 var columns = [{
        label: "", //wasn't able to inject an HTML <div> with image here
        field: "OBJECTID",
        formatter: makeZoomButton
      }, {
        label: "Location",
        field: "Location"
      }, {
        label: "Priority",
        field: "Priority"
  ,formatter:codedValueDomain
      },{

Hello Rickey,

The above solution show the way to replace the codedDomain values before the dgrid store has been set. but, if you want to change the value using the formatter, then it is also possible. But, you need to make sure that the function passed to the formatter has access to the FeatureLayer and information regarding the field name. you need to get the field from the featurelayer for the fieldname. Then you can use the method provided in the other thread (QueryTask and coded domain values) to return the value instead of the code.

Hope this was helpful.

Thejus
