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:

<html><head>
 <title></title>
 <script language="javascript" type="text/javascript">
     var redirectTimerId = 0;
     function closeWindow()
     {
         window.opener = top;
         redirectTimerId = window.setTimeout('redirect()', 2000);
         window.close(); 
     }

     function stopRedirect()
     {
         window.clearTimeout(redirectTimerId);
     }

     function redirect()
     {
         window.location = 'default.aspx';
     }
 </script>
 </head>
 <body onload="closeWindow()" onunload="stopRedirect()" style="">
     <center><h1>Please Wait...</h1></center>
 </body></html>

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

 protected void btnOK_Click(object sender, EventArgs e)
        {

          // Your code goes here.
          if(isSuccess)
          {
                  string  close =    @"<script type='text/javascript'>
                                window.returnValue = true;
                                window.close();
                                </script>";
            base.Response.Write(close);
            }

        }

A postback is the process of re-loading a page, so if you want the page to close after the postback then you need to set your window.close() javascript to run with the browser's onload event during that postback, normally done using the ClientScript.RegisterStartupScript() function.

But are you sure this is what you want to do? Closing pages tends to piss off users.

UPDATE: I have taken all of your input and came up with the following solution:

In code behind:

protected void Page_Load(object sender, EventArgs e)    
{
    Page.ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
}

In aspx page:

function CloseWindow() {
    window.close();
}

For closing a asp.net windows application,
- Just drag a button into the design page
- Then write the below given code inside its click event
```
       "   this.close();  "
```
ie:
```
 private void button2_Click(object sender, EventArgs e)  
 {
        this.Close();
 }
```

You can close a window by simply pasting the window closing code in the button's OnClientClick event in the markup
