here is a simple example to try show what i am trying to do.
I think i have the wrong imbed point.
I have a netwebform which inputs for example an amount and percentage and saves it to a table.
when the amount or percent is changed on the form i recalc a computed field and display that on the form , it is not saved in the database .
for inserts and / or updates when i alter the field on the form the recalc is done on send newvalue to server and the correct field is refreshed.
The problem comes in when i go back to the browse , select another record and open the from.
old values of the calc field from the previous form are displayed.
I need to recalc these fields and save there session values before the user sees the screen.
I have put code in the preupdate procedure but it doesnt seem to work.
any help would be appreciated.
