Navigate back in visual webgui

I'm a newbie of ASP.NET world. I'm developing an app with asp.net and insiede of an aspx page i'm using a window form developed with visual webgui.

I've this problem: inside my form, i have a button wich has to rise an event equals to the page back button of the browser.

I tried to search informations about this, but i can't find anything unfortunately.

I think that i've to do something with the HttpContext. I tried with the Redirect function but my "previous page" is open always in a new browser window.

Can someone tell me a way on how to do this thing开发者_C百科 please?

Thank's Marco

EDIT SOLVED

button.RegisterClientAction("history.go( -1 )", "");

Cant you do this:

Response.Redirect(Request.UrlReferrer.ToString());
