Can't get the coded values of domain through a feature layer.

Hi,

I created a feature layer and associated it with a featureDataGrid for attributes edit. One field (field type is text) in this feature layer has domain setting with several coded values. But I can't get the domain values show in the field of this featureDataGrid. And I debug and find that the number of the coded values in this domain setting of the feature layer's field is 0 while debugging. It seems that the domain info is not passed corrected through feature layer.

BTW, by setting up the domain, I can see this domain setting in ArcMap while started editing.

Thanks for your input in advance,

Wei

I am not sure if you are talking about setting up your service with coded value domain attribute correctly. If so, this might help: http://help.arcgis.com/en/arcgisserver/10.0/help/arcgis_server_dotnet_help/index.html#//0093000000r0000000.htm

To know if you have set this up correctly, you can wire up to the FeatureLayer's Initialized event and check for the FeatureLayer's LayerInfo.Fields property. Each field will have these values: http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Field_properties.html

FeatureLayer l = sender as FeatureLayer;
foreach (var f in l.LayerInfo.Fields)
{
 if (f.Domain is CodedValueDomain)
 {
  CodedValueDomain cvd = f.Domain as CodedValueDomain;
  foreach (var item in cvd.CodedValues)
  {
   //TODO: check for item.Key and item.Value
  }
 }
}

Thanks, Jennifer. However, in debug mode by your code method, I can see that domain is assigned to the right field, but there is no codedvalue in this domain.

BTW, do I must create a subtype and then assign this domain to the field? Currently, I don't use subtype for my SDE feature class.

Thanks again,

Wei

When you visit the FeatureLayer URL from your web browser, do you see coded values similar to this? http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/2

If it is empty there too, then maybe the issue is with your service. I think these are the steps you do for creating a coded value domain: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Creating_a_new_coded_value_domain/001s00000004000000/

Thanks, Jennifer. I resolved this issue. It's really good to know that I can monitor the domain coded values in the REST service URL. I just forgot to restart the service after I changed the domain setting.

Have a great afternoon.
