Hello,I'm trying to use the results' attributes from an identifytask to populate a dynamic datagrid. I found an ESRI example that uses the findtask to do this, but I'm having issues with the identifyTask. The grid structure is created, but there is a problem with the itemfilereadstore. Does anybody have any examples? Or does anybody know what I'm doing wrong? My code is below:
identifyParams = new esri.tasks.IdentifyParameters();
identifyParams.tolerance = 3;
identifyParams.returnGeometry = true;
identifyParams.layerIds = [1];
identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_VISIBLE;
identifyParams.geometry = geometry;
identifyParams.mapExtent = map.extent;
identifyParams.width = map.width;
identifyParams.height = map.height;
identifyTask.execute(identifyParams, function(identifyResults){
if(identifyResults.length>0){
var items = dojo.map(identifyResults, function(result){
var graphic = result.feature;
switch(result.geometryType){
case "esriGeometryPoint":
symbol = new esri.symbol.SimpleMarkerSymbol();
break;
case "esriGeometryPolygon":
symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([98, 194, 204]), 2), new dojo.Color([98, 194, 204, 0.5]));
break;
}
graphic.setSymbol(symbol);
map.graphics.add(graphic);
return result.feature.attributes;
});
var fieldName;
var fieldNameArr = [];
var selectedLayer;
clearSelectResults();
for (fieldName in items[0]) {
if (items[0].hasOwnProperty(fieldName)) {
fieldNameArr.push({
field: fieldName,
name: tableNames(fieldName),
editable: false
});
}
}
var data = {
identifier: "OBJECTID", //This field needs to have unique values
items: items
};
var store2 = new dojo.data.ItemFileReadStore({ data:data });
var children = dojo.byId("wellsTab");
while(children.firstChild){
children.removeChild(children.firstChild);
}
wellsGrid = new dojox.grid.EnhancedGrid({
query: {
OBJECTID: '*'
},
clientSort:true,
autowidth:true,
structure:fieldNameArr,
rowsPerPage: 250,
plugins: {
indirectSelection:{
name:"Select",
field:"Select",
width: "70px",
styles: "text-align: center;"
}
}
});
dojo.byId("wellsTab").appendChild(wellsGrid.domNode);
wellsGrid.setStore(store2);
dijit.byId("bottomTabs").selectChild(dijit.byId("wellsTab"));
wellsGrid.startup();
wellsGrid.update();
wellsGrid.rowSelectCell.toggleAllSelection(true);
wellsGrid.resize();
dojo.connect(wellsGrid, 'onDeselected', function(rowId){
map.graphics.remove(results.features[rowId]);
});
dojo.connect(wellsGrid, 'onSelected', function(rowId){
map.graphics.add(results.features[rowId]);
});
}
});
