Timed redirect without javascript? 1

[jacktripper]

I've done a lot of simple pages which redirect after X number of seconds using a javascript function called from the body onload parameter. But, I'm confused on how I can do this with an ASP.NET web form.

So far, I've been able to call some simple javascript functions based on a button event in the code-behind. But how can I run a javascript function from within a VB function?

Here is what I'm trying to do: I've got a web form with validation. It passes data to a web service, and gets results from the service. Based on those results, I want to have display a message on the same page (not a popup or a new page) that says "Thanks. You will be redirected to your previous location in 5 seconds." Then it auto-redirects like the javascript:history.go(-2) function.

Is this doable with javascript in ASP.NET? If I have to use javascript, how can I call a timed redirect function based on the results from a web service?

Many thanks.

Threading.Thread.Sleep(5000)

So all I do is add that line and then put a Response.Redirect after it?

 

[jbenson001]

Yes.. that should do it

Sorry, you also need this imports:
Imports System.Threading

Thanks!

no problem

Oh, whoops. But how can I reference the javascript function then? I see how this pauses the scripting for 5 seconds, but I still need the redirect to reference the client-side script for javascript:history.go(-2)

I guess you will have to add the timer in javascipt too then:

There's no difference between the simple page and the ASP.NET page really as ASP.NET simply omits HTML.

So, one method would be to simply use Page.RegisterStartUpScript (it's in the ClientScript class not Page if you are using version 2.0 of the framework) and pass in your JavaScript.

Another method would be to use the Attributes.Add of the body tag to add the onload event.
