升级到PageAdmin V2.1 20090410 ，一定要在 20090318版本的基础上升级吗？
我从去年的版本上升级的，升级完成之后浏览出现Server Error in '/' Application错误
内容如下:
{
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'lanmu3id'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'lanmu3id'.
}
刚开始以为是数据库的问题，更换为access也同样存在该问题，现在想是不是升级的时候一定要从前一个版本升呢？
