response.redirect (this page?)...short and sweet way to do this?

[darrel]

I have a 'cancel' button that should reload the current page. Ie, reset the
page back to it's initial state.

Is the best way to do this to simply have the event handler for that button
redirect the page to itself?

If so, is there a short-and-sweet way to write that out? Or do I need to
first grab the URL and parse it?

I don't want to hardcore the url as this might be used in different
locations.

You should be able to use Response.Redirect(".") or
Response.Redirect(Request.URL)

Response.Redirect(Request.URL)

Oh. Duh. Missed the obvious on that one! ;o)

Thanks!

Why not just use an HTML Cancel button and save the round trip?

That might not work correctly: if postbacks have happened
(server side validators, autopostback, ...) then the values
of that latest postback will be restored, not the real initial values!
