Closing a popup dialog after running server side code

Problem: A base page allows a user to perform additional logic such as inserting a a new row into a list via the Dialog Framework.  The new row is a custom page that is shown thru the Dialog framework.  The custom page contains a web part that allows the user to fill in a form, perform custom logic and insert the record.  You now need the dialog page/popup to close automatically after the server side code is run.  The problem is you need to run the server side code before closing the window.

Initial Hypothesis:  I have been using jQuery with a hidden server control to set a value on the server side after my custom server side actions.  Then after the page reloads due to the postback, on the jQuery $document ready I check if the hidden value has been set and if it has I use the dialog framework to close the page.  A fair amount of work and round trips to solve my problem.

I saw a post on the msdn forums which is much simpler & better solution.  I implemented this and it is much easier and better than my hidden variable approach.

Resolution:
Place the code snippet in the server side code i.e. in the button click after you have performed your server side logic.
