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
