When I create a new FeatureLayer, I need to know when it has loaded the features into the layer. Using the onLoad event doesn't get it because that only tells me when "layer properties for the layer are successfully populated."
Watching the console. I can see that all of my JavaScript code immediately after creating the featureLayer is executed before the response from the map service comes back. Therefore, if I use the featureLayer.on("load", function(){}) event, and tell it to count the number of features, it returns zero. If I execute the same count a few seconds later, it returns the expected number of features.
Example:
MyFeatureLayer = new esri.layers.FeatureLayer(mapServiceURL, {
mode: esri.layers.FeatureLayer.MODE_SNAPSHOT,
id: "MyFeatureLayer",
outFields: ["*"]
});
MyFeatureLayer.on("load", function(){
console.log("MyFeatureLayer loaded with: " + MyFeatureLayer.graphics.length + " features");
})
console: MyFeatureLayer loaded with 0 features
