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.

Response. Write("<script>window. close();</script>");
Right-click the . aspx page, and then click View Code. The code-behind file opens in the editor.
You can use Response. Close(). This will stop execution of next statements.
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); } } If you love us?
