ADO.NET :: Listbox VB Insert To Sql Data Base?

Im working with the following example and it works fine; i was wondering how to add / save data to another field at the same time:

I would like to add data to ImageID and PageID when the button is clicked... I can't seem to get the selectedvalue of the PageID from the dropdownlist..

Private Function GetConnectionString() As String
System.Configuration.ConfigurationManager.ConnectionStrings("ConnectionString2").ConnectionString

End Function

Private Sub InsertRecords(sc As StringCollection)
Dim conn As New SqlConnection(GetConnectionString())
Dim sb As New StringBuilder(String.Empty)
For Each item As String In sc

Const sqlStatement As String = "INSERT INTO Display_Logo (ImageID) VALUES"
sb.AppendFormat("{0}('{1}'); ", sqlStatement, item)
Next
Try
conn.Open()
Dim cmd As New SqlCommand(sb.ToString(), conn)
cmd.CommandType = CommandType.Text
cmd.ExecuteNonQuery()
Page.ClientScript.RegisterClientScriptBlock(GetType(Page), "Script", "alert('Records Successfuly Saved!');", True)
Catch ex As System.Data.SqlClient.SqlException
Dim msg As String = "Insert Error:"
msg += ex.Message
Throw New Exception(msg)
Finally
conn.Close()
End Try

End Sub

Protected Sub Button1_Click(sender As Object, e As EventArgs)

Dim sc As New StringCollection()

For Each item As ListItem In ListBox1.Items

If item.Selected Then
sc.Add(item.Text)
End If
Next
InsertRecords(sc)
End Sub
