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 button on the page   I have tried to programmatically add a JavaScript method that contains a window close   command to the OnClientClick event to close the page but it does not work   The button is also a asp AsyncPostBoskTrigger for an AJAX Update Panel   The application uses  NET Framework 3 5

For anyone wondering why they cannot get the provided answers to work it's because the page must have been opened by javascript in order to be closed by javascript.

Since most people finding this asp question are likely using an asp:hyperlink or an asp redirect of some sort to navigate to the page that needs to be closed. These methods of redirection don't use javascript and therefore will not close by javascript.

I found a simple solution for my application and that's eliminating the NavigateUrl and using the asp:Hyperlink.Attributes to add an onclick to the hyperlink which uses java script to open the window that needs to be closed by javascript.

aspHyperlink.NavigateUrl = "https://www.google.com";

The above NavigateUrl is removed and instead we attach our click event.

aspHyperlink.Attributes.Add("onclick", "javascript:openInNewTab('https://www.google.com');");

And in the code behind of the page containing our aspHyperlink we have the javascript for opening the url provided by Rinto

function openInNewTab(url) {
         var win = window.open(url, '_blank');
         win.focus();
     }

Now all pages opened with openInNewTab can be closed with the provided answers.

window.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
