Obtaining Results from a IdentifyResult

jonataspovoas

Hi,
I'm developing an application, and in it i get information to populate a DataGrid from an Identify Function.

My problem is that the information needs to be in a very specific order, and i'm having trouble to obtain it.

I started studying the IDictionary and found, hoping to find out my salvation, but here's what i got so far:

public class DataItem
{
 public string Title { get; set; }
 public IDictionary<string, object> Data { get; set; }
}

//This is called after the results are found!
public void getIdentifyResults(List<IdentifyResult> results)
{
 _dataItems = new List<DataItem>();
 linhaDeObservações = new List<string>();
 if (results != null && results.Count > 0) 
 {
  IdentifyComboBox.Items.Clear();
  foreach (IdentifyResult result in results)
  {
   /* there can be more than oe result, each with several 
    * lines, which i must select a few.
    */
   Graphic LineCatcher = new Graphic();
   /* The following line should get lines by it's key (like "number", for example)
    * and will be repeated several times.
    */
   LineCatcher.Attributes.Add(result.Feature.Attributes.Where(/*Don't know what to put here*/);
   
   string title = result.Value.ToString() + " (" + result.LayerName + ")";
   _dataItems.Add(new DataItem() 
   {
    Title = title,
    Data = LineCatcher.Attributes
   });
   IdentifyComboBox.Items.Add(title);
  }
  IdentifyComboBox.SelectedIndex = 0;
 }
}

Anyone can help me?

Ahh, you mean you want the results displayed in certain order according to their field names (not their values), where if results came back with Cell > Name > Number, you want to change the order to Number > Name > Cell.

In this sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Identify, you need to modify ShowFeatures() where Data can no longer be set directly to feature.Attributes.

Without any change to this sample, click on Denver. For simplicity let's look at only 3 fields. Notice the order of these 3 fields: ObjectID > NAME > STATE_NAME. If you want to change the order in which they appear, you will need something like this to force them to be in a certain order.

private IDictionary<string, object> OrderedAttributes(IDictionary<string, object> source)
{
 IDictionary<string, object> result = new Dictionary<string, object>();
 List<string> orderedFields = new List<string>() { "STATE_NAME", "NAME", "ObjectID" };
 foreach (var f in orderedFields)
 {
  if (source.ContainsKey(f))
  {
   var item = source;
   result.Add(f, item);
  }    
 }
 return result;
}
