static void CreateSqlParameterSourceVersion()
{
    SqlParameter parameter = new SqlParameter("Description", SqlDbType.VarChar, 88);
    parameter.SourceColumn = "Description";
    parameter.SourceVersion = DataRowVersion.Current;

Remarks

This property is used by the SqlDataAdapter.UpdateCommand during an update to determine whether the original or current value is used for a parameter value. This lets primary keys be updated. This property is set to the version of the DataRow used by the DataRow.Item property, or one of the DataRow.GetChildRows methods of the DataRow object.
