I have several datetime columns like this

<ig:BoundDataField DataFieldName="DateCreated" Key="DateCreated" DataType="System.DateTime" 

DataFormatString="{0:g}">

  <Header Text="Date Created" />
</ig:BoundDataField>

All works well until I try to filter on that date.  When the user types into
the filter rows edit box and hits enter.  A javascript error happens in


function Date$_expandFormat

Your switch statement doesn't appear to handle the "g" format case.  I need
to show shortdate + shorttime or "12/12/2011 12:15 PM"

Is there anything I can do to allow filtering in this scenario?  Is there anyway
to prevent the user from typing in the filter row?  Thus only allowing them to
select one of the predetermined filter row values?
