Filling a dgrid with the results of an IdentifyTask

Question

I'm building a data viewer application where a user can click on the map and see the attributes of all the features for the visible layers. This is a project I had originally built in Flex that I'm moving over to JavaScript. I would to put a dgrid into an InfoWindow that shows the results of an IdentifyTask for the visible layers in a map service. This would be similar to this sample, but using dgrids instead of tables.

I'm getting close, using this example from Derek Swingley, but I'm hitting a brick wall when it comes to creating the data store for the dgrid. While the dgrid sample shows how to do this using hardcoded field names, I have to do this dynamically. My application will be a template for several different projects, each with their own map service. Additionally, the map services may change over time, with new layers added or different fields being made visible.

Here's a snippet showing how to do this with a query task. The approach would be similar with an identify except you might have to generate the columns using the layer's field property.         var layer = results.layers[0].layer;         var q = new Query();         q.where = "1=1";         q.returnGeometry = false;          q.outFields = ["FID", "STATE_NAME","Number_Ent"]          layer.queryFeatures(q,function(queryResults){          //get the field info to build columns          var columns = dojo.map(queryResults.fields, function(field){           return {             field: field.name,             label: field.alias           }          });           //get all the attribute info          var data = array.map(queryResults.features, function(feature){             return  lang.clone(feature.attributes);           });             //create the grid           var grid = new Grid({            columns: columns          },"grid");           grid.renderArray(data);          });
