Button in ASP, called in C# file via Javascript

Question

I have a asp.net page where it has the following properties

<asp:Button ID="btnBack" runat="server" CssClass="Button" Text="< Back to Home" /></td>

And in the C# code file I am doing something like this

btnBack.Attributes.Add("onclick", "javascript:history.go(-1);return false");

The problem is it is not always returning me to the Home page but some other page..

Is there anyway I can add in this function the page where I want to navigate for instance (and I know its wrong but please see what i want to achieve)

    btnBack.Attributes.Add("onclick", "~/Home.aspx");

Something like that

I would appreciate your help

The reason you aren't always getting the behavior of moving back to the home page is because history.go(-1) just tells the browser to navigate back to the previous page that was loaded. It may not always be the home page.

A simple solution from javascript is to change the location property which will trigger the broswer to load the URL supplied

btnBack.OnClientClick = "window.location='http://www.google.com'";

The OnClientClick will attach the javascript string to the onclick event in html markup for you. This is easier and cleaner IMO than something like btnBack.Attributes.Add("onclick", "window.location=~/Home.aspx"

btnBack.Attributes.Add("onclick", "location='http://google.com'");

location is an object; you are looking for location.href, which is a string.
