formview

问题 I'm using a FormView with an ObjectDataSource and binding using <%# Bind("WhateverProp") %> - and all of my nullable columns are coming back with default values of the type in them. It appears that the FormView object doesn't have a ConvertEmtpyStringToNull property like the other binding containers do. I've found articles suggesting that this was a bug in VS 2005 / .Net 2.0 - but don't see any saying what the resolution was. Does anyone have any suggestions as to how I can work around this
