I have a datetime field with not-null=false.But while entering data if i don't enter a datetime value for that field it gives SQL datetime exception 'Datetime field must be between 1/1/1900...'

Also when I delete a record it is not able to update by cascade those tables which have null values in datetime fields.

Can anyone tell me why this happens and how I cansolve this problem?


Thanks.....

In order to handle this you have to use the Nullables library, please read the documentation on how to use this.
