Close web form from code-behindHi all:
I have a button on a web form that calls a method in the code-behind file, OnClick="cmdButton_Click" and I am wondering if it is possible to close the web form from the code-behind? Or would I have to use client-side script to call the code-behind method, and then close the form from the client? Can anyone make a suggestion and/or point me at an info source? Thanks all! John.

You can, of course, use code-behind to generate client-side JavaScript which will be streamed to the client along with the rest of the HTML stream. However, unless you need to perform server-side processing, there is no need to use a server-side method for this e.g. <asp:Button ID="cmdClose" runat="server" OnClientClick="window.close();" Text="Close" /> However, this will (almost) always pop up the "Something is trying to close this window" confirmation message. It used to be possible to prevent this in earlier versions of IE (and some other browsers), but this has thankfully now been fixed in most later versions... Hi mark:
Thank you for your reply. Yes I do need to perform server-side processing, so am I out of luck to close the form? John.

An even better option is outputting client script, but I felt I was more likely to have to test the code if I did that. The end result is you are injecting javaScript to close the page. -- Show quoteHide quoteGregory A.

Note to self: type="text/javascript" is probably better here. I generally do not have to type these things out any more due to Intellisense. Damn you Intellisense. -- Show quoteHide quoteGregory A.
