Codegen not working

My header is as follows:

<xs:schema id="dsClientT"
targetNamespace="http://www.tempuri.org/dsClientT.xsd"
xmlns:codegen="urn:schemas-microsoft-com:xml-msprop"

xmlns:mstns="http://www.tempuri.org/dsClientT.xsd"
xmlns="http://www.tempuri.org/dsClientT.xsd"

xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"

attributeFormDefault="qualified" elementFormDefault="qualified">



My element line is:



<xs:element name="WorkCDN" codegen:nullValue="0" type="xs:boolean" />



However, when I call Addnew() if I have databinding on checkbox it still
doesn't work, it seems the datarow that is returned is still returning
dbnull and and not flase for this boolean variable.

Any inputs ?
