Improved Navigation Techniques

[Mike555]

In my application I have a built-in "Back" button at the top of every webform, and I have instructed users to use this "Back" button instead of the IE Back button for obvious reasons.

My back button uses a Response.Redirect call to take the user back to the previous page

My problem is... Since none of my webforms have 1 single entry point, In order to determine where the user came from, I need to pass in an extra variable ("BackTo") into each webform. This extra variable contains the name of the previous webform where the user arrived from. The Back button then sends the user back to that page.

Response.Redirect(Request.QueryString("BackTo"))

Is there an easier way to do this? I have that unsightly feeling that tells me this should be much easier than I'm making it. Thanks.

Regards,
Mike

Hi,

Not necessarily an easier way, but one where the URL is not exposed in the querystring, in case this is an issue.

In the page load event,

If ( !IsPostBack ) {
ViewState["UrlReferrer"] = Request.UrlReferrer.ToString();
}

in the appropriate event, redirect to the value contained in the viewstate variable.

akohli,

I see that this method works when a page is opened via a URL but does not work when, for example, a page is opened via a Request.Redirect("pagename"). Is it possible to capture the previous page when Request.Redirect is used? Thanks.
