How to set Option set value in CRM 2011?

Question

I have an Option set in CRM 2011. It has four options:

1. Public
2. Private
3. Subsidiary
4. Other

Through plugin I want to set the value of this option set. Can anyone provide me the statement to set the value of this option set?

Answer 1

How to set optionsetvalue in plugins

In plugins you can write yourEntity.yourAttribute = new OptionSetValue(INDEX); The INDEX is an int you can look up in your optionset editor (default values are several digit long).

OR

You set the optionset like yourEntity.Attributes.Add(“yourAttribute”, new OptionSetValue(INDEX));

Answer 2

You can set an option set value using the following:-

OptionSetValue myOptionSet = new OptionSetValue();
myOptionSet.Value = xxxx  
myEntity.Attributes["optionSetAttributeName"] = myOptionSet;

// Where xxxx represents the value desired and can be checked on the attribute metadata page within the entity customisations

Whether 'myEntity' is actually preImage/postImage or just a dynamically created entity in the plug-in will determine whether you need to actually call the update method, but essentially this is the way you set the option set value and update the attribute.
