Hi, whats the best practise for implementing a confirmation page in .Net?

I've used response.redirect("Thankyou.aspx") a lot in the past I've also used something like this for hiding form controls and outputting a message:

outResult.Attributes.Remove("style") outResult.Attributes.Add("style", "display:block;") outEntry.Attributes.Remove("style") outEntry.Attributes.Add("style", "display:none;")

For the above you have to consider post backs that may occur if the user click refresh though.

Does anybody have a better option? thanks!
