Hello,
We use Tornado.dll Ver 4.6.11.10
Tornado gives an error when the checkbox is checked.

Error:
Edit SQL = UPDATE Products SET Productname='Alice Mutton',discontinued=on WHERE (Productname='Alice Mutton')
--------------------------------
System.Data.OleDb.OleDbException: Incorrect syntax near the keyword 'on'.

Sample code:
<%@ Page Language="vb" Debug="true" %>

<script language="vb" runat="server">
Sub Page_Load(Source as Object, E as EventArgs)

Dim GD As New Tornado.Getdata()
Dim NWTest As New Tornado.Z()
With NWTest
.dbUnit = "627"
.dbSkin = "12"
.dbPageSize = "10"
.dbDBType="SQL"
.dbMode = "type=Grid|sysindex=true|classic=true"
.dbDSN="localhost;Northwind;xxx;xxx"
.dbSQL="Select Productname, discontinued from Products order by Productname"
.dbBoolText="DropTrue=1|DropFalse=0"
.dbSortFlds = "Productname"
.dbNavigationItem = "gridupdate,cancel,prev,next"
.dbGridDisplayFlds = "Productname,discontinued"
.dbEditUpdateFlds = "fi=Productname|tag=size=40|ty=text,fi=discontinue d|ty=checkbox"
.dbBookMark = "Products;0"
.ASPdbNET()
End With
End Sub
</script>

Thank you
Thomas
