Where in the page lifecycle does validation occur? -- asp.net building controls

Thanks Teemu,

If I don't want to use button events (to avoid the need for javascript)
where's the best place to check if the posted data is valid and do
database updates, redirects etc.?

Thanks,

Paul

Hi,

it happens just before postback events are raised (after Page_Load). In
practise, if you have a Button on Page which triggers validation, it happens
just before Button's Click event is raised. In the Button's Click event, you
could then just check Page.IsValid.

Just before you need the data. generally you'd want to use events as they
help in keeping the page code structure clean. Otherwise you have code
centralized in one place trying to deal all cases.

Note that Js validation isnt that bad, you have server-side validation
backing it up in any case.
