SharePoint: Get All Possible Values of Choice Column Dynamically

Scenario:

We need to populate an asp DropDownList control with all possible values of a choice column created in a specific SharePoint list.

Resolution:

SPList spList = spWeb.Lists[“ListName”];

SPField spField = spList.Fields[“ColumnName”];

XmlDocument xmlDoc = new XmlDocument();

xmlDoc.LoadXml(spField.SchemaXml);

XmlNodeList nodeList = xmlDoc.SelectNodes(“/Field/CHOICES/CHOICE”);

foreach (XmlNode node in nodeList)

{

    ddl.Items.Add(node.InnerText);

}
