>My SP has FatherID and MotherID as update parameters, not Father or Mother. I already tested this SP in SSMS, it works fine.
>
>In my ASPX I don't have Father or Mother as UpdateParameters either (only FatherID and MotherID). However, I get Father & Mother (as first name + last name) as part of the select and bind a textbox text to it.

>Do you know what the problem here is?

>Of course, I can add these two extra parameters to my SP to prevent this error, but why does it try to send them as Update Parameters?
