How to get the option set from a field in an entity in CRM 2011 using crm sdk and C#

Question

How to get the option set from a field in an entity in CRM 2011 using crm sdk and C#? I just want to share with you guys a direct approach on getting the option set of a field in an entity.

Answer 1

The proper way to retrieve metadata information in Dynamics CRM is to retrieve only the information required. We should only retrieve the option set values based on the original question. Retrieving all the metadata for an entity when all the requirement specifies is the values for an Option Set is unnecessary and will create unnecessary overhead.

Here is the correct way to get the list of options for an Option Set.

    public static void GetOptionSet(string entityName, string fieldName, IOrganizationService service)
    {

        var attReq = new RetrieveAttributeRequest();
        attReq.EntityLogicalName = entityName;
        attReq.LogicalName = fieldName;
        attReq.RetrieveAsIfPublished = true;

        var attResponse = (RetrieveAttributeResponse)service.Execute(attReq);
        var attMetadata = (EnumAttributeMetadata)attResponse.AttributeMetadata;

        var optionList = (from o in attMetadata.OptionSet.Options
            select new {Value = o.Value, Text = o.Label.UserLocalizedLabel.Label}).ToList();


    }

Answer 2

This method needs the entity name, name of the field which contain the option set and the instantiated IOrganizationService.

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Messages;
using Microsoft.Xrm.Sdk.Metadata;

    public void GetOptionSet(string entityName, string fieldName, IOrganizationService service)
            {
                RetrieveEntityRequest retrieveDetails = new RetrieveEntityRequest();
                retrieveDetails.EntityFilters = EntityFilters.All;
                retrieveDetails.LogicalName = entityName;

                RetrieveEntityResponse retrieveEntityResponseObj = (RetrieveEntityResponse)service.Execute(retrieveDetails);
                EntityMetadata metadata = retrieveEntityResponseObj.EntityMetadata;
                PicklistAttributeMetadata picklistMetadata = metadata.Attributes.FirstOrDefault(attribute => String.Equals(attribute.LogicalName, fieldName, StringComparison.OrdinalIgnoreCase)) as PicklistAttributeMetadata;
                OptionSetMetadata options = picklistMetadata.OptionSet;
                var optionlist = (from o in options.Options
                                   select new { Value = o.Value, Text = o.Label.UserLocalizedLabel.Label }).ToList();

                //from here you can do anything you want now with the optionlist

            }

I hope this will help some of you guys with your project.

Answer 3

Hey why not use this ??

OptionSetValue CountryOptionSet = Contact.Attributes.Contains("gr_address2_country") ? Contact["gr_address2_country"] as OptionSetValue : null;
 if (CountryOptionSet != null)
                     string Country = CountryOptionSet.Value.ToString();

Answer 4

depends if it's local or global. If it is local then:

string optionsetText = entity.FormattedValues["new_optionset"];

if its global then you need a lot more code:

        public static string GetoptionsetText(string entityName, string attributeName, int optionSetValue, IOrganizationService service)
    {
        string AttributeName = attributeName;
        string EntityLogicalName = entityName;
        RetrieveEntityRequest retrieveDetails = new RetrieveEntityRequest
        {
            EntityFilters = EntityFilters.All,
            LogicalName = EntityLogicalName
        };
        RetrieveEntityResponse retrieveEntityResponseObj = (RetrieveEntityResponse)service.Execute(retrieveDetails);
        Microsoft.Xrm.Sdk.Metadata.EntityMetadata metadata = retrieveEntityResponseObj.EntityMetadata;
        Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata picklistMetadata = metadata.Attributes.FirstOrDefault(attribute => String.Equals(attribute.LogicalName, attributeName, StringComparison.OrdinalIgnoreCase)) as Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata;
        Microsoft.Xrm.Sdk.Metadata.OptionSetMetadata options = picklistMetadata.OptionSet;
        IList<OptionMetadata> OptionsList = (from o in options.Options
                                             where o.Value.Value == optionSetValue
                                             select o).ToList();
        string optionsetLabel = (OptionsList.First()).Label.UserLocalizedLabel.Label;
        return optionsetLabel;

I got that from Guido on another similar question but rcados is missing the 3rd parameter. To get the text you just set

var foo = GetoptionsetText("lead", "picklist", 1234 , service)

assuming you have already declared IorganizationService

Answer 5

There are two way to get text of OptionSet:

First:

OptionSetValue opProductType = new OptionSetValue();
opProductType = (OptionSetValue)item.Attributes[attributeName];
var optionValue = opProductType.Value;

Second:

var StatusString = TermAndCon.FormattedValues[attributeName].ToString();

(Set) Post OptionSet Value :

newSalesOrder[attributeName] = new OptionSetValue(Convert.ToInt32(optionValue));
