Programmatically close aspx page from code behind

Question

What is the best way to close an ASPX page from the code-behind?

I have a button event handler that I want to close the page after the user has clicked an ASP.NET

You would typically do something like:

protected void btnClose_Click(object sender, EventArgs e)
{
    ClientScript.RegisterStartupScript(typeof(Page), "closePage", "window.close();", true);
}

However, keep in mind that different things will happen in different scenerios. Firefox won't let you close a window that wasn't opened by you (opened with window.open()).

IE7 will prompt the user with a "This page is trying to close (Yes | No)" dialog.

In any case, you should be prepared to deal with the window not always closing!

One fix for the 2 above issues is to use:

protected void btnClose_Click(object sender, EventArgs e) {
    ClientScript.RegisterStartupScript(typeof(Page), "closePage", "window.open('close.html', '_self', null);", true);
}

And create a close.html:

 
 
 
 
     
Please Wait...
 

Note that close.html will redirect to default.aspx if the window does not close after 2 sec for some reason.
