Postback using javascript

Question

How to cause a postback using javascript in ASP.NET.

Answer 1

<script language='Javascript'>
__doPostBack('__Page', 'MyCustomArgument');
</script>

or if you just strictly want a postback you can send a null argument

<script language='Javascript'>
__doPostBack('__Page', '');
</script>

Answer 2

Jacobnlsn is correct. However, if you want to do custom handling of the postback on the page as well, take a look at the IPostbackEventHandler interface.
