Perhaps there is code here that can help. I know I have code that takes the options and stores it in the database as comma sperated values and then reads from the database to display the results.

here is a piece:

                       Case "System.Web.UI.WebControls.CheckBoxList"
                        tempCheckBoxList = CType(Item, CheckBoxList)
                        objItemType.ItemTypeName = "CheckBoxList"
                        objItemType.ItemName = tempCheckBoxList.ID

                        Dim strSelectedItem As String = ""
                        Dim objListItemCollection As ListItemCollection = tempCheckBoxList.Items
                        Dim objListItem As ListItem
                        For Each objListItem In objListItemCollection
                            If objListItem.Selected Then
                                strSelectedItem += objListItem.Value.Replace(",", "") & ","
                            End If
                        Next

                        If strSelectedItem <> "" Then
                            strSelectedItem = strSelectedItem.Substring(0, (strSelectedItem.Length - 1))
                        End If

                        objItemType.ItemValue = strSelectedItem
