Stumbles and Travels

This is a quick post on how to add another value to a Multi-choice field using the object model.  The code is below and assumes that you already have a reference to your SPWeb object stored in ‘myWeb’.

SPFieldMultiChoice myField = (SPFieldMultiChoice)myWeb.Fields["Field Name"];
myField.Choices.Add(“Value to add”);
myField.PushChangesToLists = true; //Set to false if you don’t want Lists/Content types to update automatically
myField.Upate();
