Response.Redirect() in iFrame, redirect parent window

Question

I know this isn't possible, but what is the best alternative for wanting to do Response.Redirect from an iFrame, to redirect the parent page?

Answer 1

You can not do this using ASP.NET. ASP.NET on server side can redirect incoming request and can't know about a parent frame.

But if you want to redirect parent frame on some server side condition you can call JavaScript from server like this:

protected void Page_Load(object sender, EventArgs e) {
   ClientScriptManager.RegisterClientScriptBlock(this.GetType(), 
       "RedirectScript", "window.parent.location = 'http://yoursite.com'", true);
}

And of course you can use simple JavaScript window.parent.location = 'http://yoursite.com' on client side.
