Going back to calling page

[BillGatesFan]

Let's say I'm in a.aspx and I do a response.redirect to b.aspx. Then I
show and hide a couple of panels in b.aspx and now I want to click a
button to take me back to a.aspx. how do I do that without doing
response.redirect?

What's wrong with Response.Redirect?

You can use the meta tags or javascript to move the page client side, or
server.transfer server side...I would redirect to the referrer.

The problem with it was I needed to go back to the correct page. My
example was kind of wrong. I'm on c.aspx, a.aspx and b.aspx could get to
c.aspx. How do I get back to the correct one that got me to c.aspx? If I
knew which one, then I could use response.redirect.

One method is to add the referer to Viewstate the first time the page
is loaded (Postback == false). This example uses a button, but once you
have the referer you can do whatever you want with it.

private void Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
{
BackPath = Request.UrlReferrer.ToString();
ViewState.Add("BackPath", BackPath);
}
else
{
BackPath = ViewState["BackPath"].ToString();
}
}

private void btnBack_Click(object sender, System.EventArgs e)
{
Response.Redirect(BackPath, false);
}

There are some other, more sophisticated approaches. Juval Lowy has
written a server control that handles this functionality:
