FormView Update fails with InvalidCastException

[Guest]

Hi,

I have a FormView control on a page which is bound to a SQLDataSource table.
Everything works fine except for the "Update". I get an
InvalidCastException. The problem only seems to surface when I have a
'datetime' column in the table. I tested this with a very simple sample
table. As long as there is no datetime column either in the table or on the
form, all are peachy. Here is the code, in case somebody can figure it out.
I would really appreciate a post if you know a solution.
