Invalid cast from 'Int32' to 'DateTime'

[Guest]

Dears,

I'm trying to update a record in database with fields such as:

ID int32, title string, body string, datePublished datetime, <nullable>
dateEdited datetime

which are sent to object data and then sent to store procedure, when I try
to run the page and update the record it gives me this error, I feel the
DateEdited is the source of this, but couldn't find a clue.

Can you help please?

Thank you.
