Hi,

I am looking at making images/links visible and invisible when a user is redirected from a page but do not know really where to start on this one.

I have been looking round and found

if page.previouspage ! = (page.aspx) then
result here
end if

but this doesnt work...

Any suggestions?

Thanks

There are several ways to go about doing this.  Probably the easiest way would be to use query string parameters.

Code for page doing the redirect:
Response.Redirect("NewPage.aspx?showImage1=true&showImage2=false")

Code for page selectively displaying images/links:
protected void Page_Load(object sender, EventArgs e) {
  image1.Visible = bool.Parse(Request.QueryString["showImage1"]);
  image2.Visible = bool.Parse(Request.QueryString["showImage2"]);
}

Thank you for your response, I see that you have provided a solution in c#, and apologise for not saying earlier, but I am writing in VB.NET.

I have tried the request.querystring as you suggest, however this is coming up with a value of type system.collections.specialised.namevaluecollection cannot be converted to string.

Any suggestions?

It has been quite some time since I have written VB.NET code, if I remember correctly, it would look something like this::
Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)
  image1.Visible = Boolean.Parse(Request.QueryString("showImage1"))
  image2.Visible = Boolean.Parse(Request.QueryString("showImage2"))
End Sub
