passing the current URL

[mattbold]

hello

I've just been pondering this and wondered if any of you could aid me

I'm adding a simple dynamic online help bit to my site, it is one page (help.aspx) and shows help text appropriate to the page that linked to it. This works fine, but now i'd like to add a link that goes back to the previous page, and i'm pondering how to achieve this. i could pass the URL of the page to the help page in the querystring and use that in making the link, but that seems a little silly... i'm sure there's a much better way, can anyone help?

cheers ,
matt

Or if you want to do this in the code look at using
Request.URLRefferer

hello,

Yes i would prefer to do it in the code, i've been trying all sorts of options on the request.URLReferrer, but i keep getting &quot;Object reference not set to an instance of an object.&quot; i've tried things like:

hyperlink1.NavigateUrl = Request.UrlReferrer.LocalPath
and
hyperlink1.NavigateUrl = Request.UrlReferrer.AbsolutePath

i've also tried setting the text of a label using request.urlreferrer but i still get the same error..

any chance of a few more pointers?
